Protect Yourself From Government Cellphone Surveillance [Android]


cell phone surveillanceLet’s face it, these days the likelihood that you are being monitored by someone is rising all the time. I’m not saying that everyone, everywhere faces the threat of cellphone surveillance, but there are plenty of situations where you could be at risk without realizing it.



How To Protect Yourself From Government Cellphone Surveillance [Android]


Maybe you’re an activist on the streets of New York City, with the police and FBI parked outside of your apartment building. Maybe you’re a freedom fighter in the Middle East, trying to get the news out about conditions in your country. Or maybe you’re a journalist working somewhere in the world where there’s government corruption and you’re trying to expose it.
It doesn’t take much to become targeted by both amateurs and professionals alike, for eavesdropping and surveillance.  A New York Times article from March revealed that police agencies in the U.S. are increasingly using cellphones to perform surveillance on suspected individuals. This isn’t to say they are only using the technique on confirmed criminals – all you have to be is “suspect” to face the threat of “big brother” analyzing your every move.
Even in the face of overwhelming surveillance and even professional attempts to gather information about you through your phone, there are a few steps that you can take to protect your personal information. At the very least, the tools and tips that I’m going to introduce you to in this article will make it significantly more difficult for anyone to find out what you’re doing with your phone.

Protecting Your Cellphone From Surveillance Attempts

Tracking someone with a cellphone is a popular request – jilted former boyfriends or girlfriends want to know how to track someone, suspicious wives or husbands are always asking how to do it, and the list goes on. One of my most popular articles that I’ve ever written just happens to be about how to trace a cellphone with Google Latitude. To this day, I still get requests from people asking me to help them track someone’s cellphone.
Steve also covered the topic, explaining how to find your friends via GPS. The danger of being tracked is so real that Christian felt compelled to write an article helping people turn off “localization” on their phones. But is turning off those services enough to protect yourself?

Encrypting Your Notes

The truth is that turning off those apps and services that track your location is only the first step. I highly suggest you take Christians advice and do that as a first step. It’s all too easy to track someone that has turned on their GPS and enabled some app that reports out to Latitude, Facebook or Twitter.
However, the next step is making sure that the undercover guys sitting in the van out in the street can’t intercept your email, your text messages, and your phone calls. You also need to protect the data that you store on your phone. In this article, I’m going to help you encrypt and protect all of that information.
If you need to keep track of private information, like passwords or account numbers, on your mobile phone, install Safe Notes. Safe notes will store those critical notes behind a PIN number of your choosing.

cell phone surveillance

Of course, just having a PIN number to access stored notes will not protect the data from someone that can gain access to your data directory on your phone, and attempts to extract the text from your note through some back-door technique. For that contingency, Safe Notes stores all of your entered notes on your phone using 128-bit encryption.

government surveillance

That means that any information you store within Safe Notes will truly be protected from prying eyes. Only the most sophisticated, tech-savvy hacker would even stand a chance of cracking that, and such a hacker is not going to be on the payroll of the police department. You might have to worry if the FBI is involved – but even then, you’d have to be worth the effort for the Feds to try to break the 128-bit encryption.

Encrypting Text and Email

Another big concern isn’t just the information you have stored on your smartphone, but the information you have streaming in and out of it in the form of text messages and email. One simple app that can help you protect those transmissions is Encrypted Messages by Hacker Daily.

government surveillance

This app lets you create a text message that you want to transmit, give it a password, and then receive the message in encrypted form in the message box at the bottom of the app. The only way anyone will be able to decipher that strange mix of text and characters is if they have the Encrypted Messages app, and if they know the correct password.

government surveillance

If you click on the “Mail” button, the app will actually compose the email for you using your default email app, and it’ll paste your encrypted message into the body. All you have to do is hit Send.

cellphone surveillance

The person receiving the encrypted message can simply paste the message into the app, type the correct shared password, and read the decrypted text in the bottom window.

cellphone surveillance
I
t really doesn’t get much simpler than that.  The good thing about this kind of setup is that if the password ever gets compromised, you can both simply agree on a new password and start sending encrypted messages safely again.

Encrypting Voice

Encrypting text is all well and good, but what about all of the phone calls that you make? What is stopping someone from intercepting those transmissions in mid-air and listening in on your conversation? Realistically, not a whole lot.
As the world becomes more and more mobile, people become more and more susceptible to conversations getting intercepted. You may not think voice conversations hold a lot of private information, but think about everyone you talk with on your phone – your doctor, your lawyer, or your business associates.
Voice is trickier to encrypt, but not many people realize that the HeyTell VoIP app actually encrypts all data and audio in transit.

cellphone surveillance

Just set your privacy high so that only you can decide who you communicate with, and then start using the app. It’s a very cool app that can replace phone calls to any friends or associates that are also running the application on their smartphone.


It basically turns your phone into a press-to-talk capable phone – converting your cellphone into a digital walkie-talkie with encrypted transmissions!
So, you’ve got your notes, your text messages, your emails, and your voice transmissions all encrypted and protected from government surveillance, so is there anything left?

Lock Up Passwords and Accounts

I know I mentioned that SafeNotes could be used to encrypt text like passwords, but if you really want double-security for your critical, private information, then you’ll want to install MindWallet.
MindWallet is a popular data-protection app that stores your account and password information behind military-grade encryption – a 128 bit AES algorithm.



Your Master Password doesn’t get stored anywhere in plain text, not even on your phone, so it’s a password that you don’t want to forget. It is your key to everything. Once you log in with that Master Password, you can store everything – bank account details, critical websites, your email account details, credit card accounts, and any other username/passwords you need to remember.



The cool thing is that you aren’t limited to the templates that come with MindWallet. If there’s information that’s very specific that you want to lock away, just create your own database entry fields and add them to your own custom “item” that you want to store inside your secure “wallet”.

cell phone surveillance

When it comes to surveillance, the main reason police and even journalists have been able to hack so easily into the personal details of cellphone users is because no one bothers to protect themselves. Voice and data gets transmitted without even a bit of security in most cases. By adding the sort of high-level encryption found in the apps above, you will make yourself a much smaller target that is nearly impenetrable to most surveillance attempts.
Encryption is the key. Give the apps above a try and let us know how well they worked out for you. Were they convenient enough, or did they hamper your use of communication apps? Share your thoughts and insights in the comments section below.

How To Make Free VoIP Calls from Google Voice

From LIfeHacker.com

Google Voice is great, but it isn't an entirely free voice-over-internet service if you have to pay a phone bill to use it. With a few tweaks, though, you can make completely free internet phone calls with Google Voice. Here's how.


Note: Gizmo5's desktop software once offered great free VoIP calling through Google Voice. So great, in fact, that Google bought the maker, closed sign-ups, and now sits on it. Here's the new, up-to-date, and completely free way to make free internet calls with Google Voice.
When you've got Sipgate set up as one of your Google Voice numbers, you can, basically make and receive calls from your computer as if it were just a large and awkwardly designed cellphone. You can still pick up calls to your main number on your cellphone or other lines, or just pick it up on your laptop or desktop, with a good headset or just your built-in mic and speakers. You'll save yourself cellular minutes, possibly experience better call quality, and record calls with ease.


Not quite sure what Google Voice does, or why you'd want it? We've been there ourselves. Skim through our takes on whether you'd actually need Google Voice, how to ease your transition to Google Voice, or simply skim through Google's comprehensive video guide, the introduction to which is below:
When you're done setting up a free VoIP service through Google Voice, you'll be able to pull off the same kind of free calling from your desktop as you could once do with Gizmo5—but with Gizmo5 closed to sign-ups at the moment, and no word from Google on future digital calling, this is the cheap and easy way to go, for the time being.

What You'll Need

  • Google Voice account: Google Voice is a free service that, as of June 22nd (today if you're reading this when it published), is available for everyone in the U.S. and Canada. All you need to use it is your Google account, so head to the Google Voice homepage and sign on in to get started (if you haven't already).
  • Sipgate account & phone number: Both are free—even the real phone number that folks can call you on all they want. Sipgate has many neat services to recommend it beyond its free Sipgate One service-with some cheap hardware, you could set up what amounts to a very cheap digital phone network, in your house or with a small telecommuting team. For now, though, we're just going to hook up a Sipgate One phone account and number up to Google Voice.
  • Audio tools for computer calls: You can make and take phone calls using your laptop's microphone and speakers, but if you're going to be talking regularly, you'll probably want to upgrade to a decent USB headset with microphone.
  • Cellphone with text messaging: Just for a verification code that Sipgate sends. You won't need the cellphone to actually use your free VoIP setup.

Step 1: Set Up Sipgate

Setting up a Sipgate account is a pretty familiar process, and less intensive then, say, Google Voice. Here's the abbreviated walkthrough:


Make Free VoIP Calls from Google Voice

Head to the Sipgate One site and click the "Sign up now" button. You'll be asked to provide your cellphone number and carrier, then get a text message with a short verification code.


Make Free VoIP Calls from Google Voice

After filling it in, you'll be asked to provide some information: name, address, email, and a password. The email must be real and used, because you'll use it to verify your account further. The address, if you don't love the idea of giving it away, can be relative—it's used primarily to pin down your location and figure out which area codes you'd want.

About those area codes—Sipgate doesn't offer all of them. In fact, in upstate New York, Sipgate only offered 518 and 845, and after selecting 518, it turns out Sipgate plum ran out. I had to pretend like I lived in San Diego (good people live there!) to pin down a number, but since this is a software phone and I'm connecting through my proper Google Voice number, it didn't really matter to me. Your mileage may vary, but your friends and contacts are only calling your Google Voice number, which then rings you on your computer, so the actual number doesn't matter all that much.


Make Free VoIP Calls from Google Voice

Once you've picked out and confirmed your number, you'll be asked to download and install the software. I'd recommend just downloading, but not yet installing and launching the Sipgate desktop software. Respond to your email activation message, and keep moving through the setup process.
You'll eventually arrive at a screen where you'll have to pin down an exact address, for what I've reasoned is the inclusion of E-911 data with the phone number Sipgate is issuing you. Depending on the area you're trying to obtain a phone number in, you may end up with a failure message indicating that there are no numbers available for the address and area code you picked out. This is how I ended up virtually moving to San Diego. Be sure to pick out the options indicated for a free, single number, so that your sign-up form looks akin to this:


Make Free VoIP Calls from Google Voice


Head into your Sipgate settings by signing in (upper right corner) at Sipgate.com, then clicking "Settings" in the upper-right corner. In the default "Phone" section, you'll likely see the cellphone you provided as linked to your account. Mouse over that cellphone, and select either "Delete device" (which most of us can safely do), or "Deactivate" (if you think you might pull off some fancy VoIP-to-cell tricks in the future). Either way, you want "Phone of (Your Name)" to be the primary call taker, since that's your Sipgate number. If Sipgate bugs you to set up routing to your phone, go ahead and click the link to do so. Your Sipgate routing setup should, in the end, be very simple—one phone number rings one (virtual) phone.


Make Free VoIP Calls from Google Voice


There's one last area to address inside Sipgate, because the service tends to capture its incoming calls with its own voicemail system, rather than letting Google Voice pick up the unanswered call. Head into Sipgate's voicemail, call forwarding and hunting rules.


Make Free VoIP Calls from Google Voice

To put it simply, you're going to clear out everything—any forwarding rules, the basic voicemail condition, all of it. When you're done, this settings area should look like the example at left, with Sipgate indicating "You have not set up voicemail or call forwarding" for either your number or your account.
Once that's done, you could log into your Sipgate software and test it out by calling your new number from a cellphone or landline, but you don't need to—we're going to have Google Voice call you anyways, to connect your number.

Step 2: Connecting to Google Voice

Make Free VoIP Calls from Google Voice


Head to your Google Voice "Phones" settings and click the "Add another phone" link at the bottom of your list. Enter a name (maybe "Sipgate") and the phone number Sipgate assigned you, with area code, along with picking a phone type ("Home" or "Work" should play) and un-checking the "Receive text messages" option, then hit "Save." Google Voice will now ask to call that number and have you punch in a two-digit code to verify it's yours.
Make sure your Sipgate software is running, and that you're signed in, and then go ahead and authorize Google Voice to call. When the call comes through, switch over to the "Dialpad" tab on your Sipgate window, type in the code provided at the Google Voice site, and you'll hear Voice congratulate you on hooking the two together. You can now head back to your Phones settings at Google Voice, choose Advanced Settings, and detail exactly when your Sipgate number should ring.

Step 3: Using Sipgate from Your Computer

Make Free VoIP Calls from Google Voice

On both Windows and Mac, Sipgate's software is fairly minimalist—if you're used to Skype's mannerisms, it'll seem nearly invisible. It's a rectangular box with just four tabs, and its main purpose is to sit there and wait for you to dial a number or receive a call. That's fine for accepting calls—when you want to make a call, you're going to use Google Voice tools.


Make Free VoIP Calls from Google Voice


Sipgate gives you 60 free outbound call minutes with your phone number, but you don't really need to use them. Google Voice is a pretty ubiquitous service, at least where internet service is available. From a laptop or desktop, you can use a few tools to place an outgoing call—which will technically call you on your Sipgate number, then connect the call when you pick up.
  • Browser extensions: Google has an official Chrome extension that's pretty nifty, and Chad Smith regularly patches up an unofficial, experimental Firefox add-on that offers similar capabilities: click-to-call, call logs, SMS, and the like.
  • Google Voice web site: Keep it open in a tab, or maybe as a stand-alone browser app, and learn the basic shortcuts—specifically, "c" to make a call. There are, of course, many others to master.
  • Desktop tools: In addition to the single-site browser tools we've detailed that would work great with Google Voice, a few tools have been put together to tuck Google Voice calling onto your taskbar or system tray: Google Voice for Adobe AIR (all platforms), and Voice Mac (Mac only).
Make Free VoIP Calls from Google Voice


One final note on a little side-benefit of Sipgate—the software can natively record calls. Google Voice can record calls, too—but only on an incoming call, and you have to pull up the dialpad and press "4." Sipgate's desktop software simply records your call and offers it up as an MP3 when you're done. Like Google Voice, Sipgate will make a very obvious announcement that it's recording the call, to comply with the many different call-recording laws, but it's a pretty nice feature on the whole.

Big thanks go to reader Justin, who originally came across the Sipgate/Voice combo and blogged about it, along with tipping us. Got your Google Voice/Sipgate setup running and digging it so far? Having a problem, missing a feature from Gizmo5, or have another tip for a better free phone life? Tell us your take in the comments.

How to Make Free Phone Calls from iPhone - 3 Articles




No one likes using up their cell phone minutes, and that is where VoIP services come in handy. VoIP offers up an inexpensive alternative to traditional phone calls, making VoIP for the iPhone a great deal.
While the iPhone has not officially supported VoIP service, Apple isn’t saying it’s not allowed either. With all of that in mind, there are two camps of VoIP services popping up for the popular Apple device: official applications and Web based solutions.  Each style has their pros and cons, but there is sure to be something in these eleven options to help you meet your needs.
Which service is your favorite?

Applications

Fring – Fring gives you the ability to instant message your contacts on AIM, Google Talk, ICQ, MSN Messenger, Skype, Twitter and Yahoo via EDGE, GSM, 3G and Wi-Fi on both the iPhone and iPod Touch.  If you are on an iPhone, you can also use it to connect with Skype, Skype Out and other SIP services.  You can read more about it in our review of Fring.
iCall – This app will allow you to switch an already in progress call over to Wi-Fi, or you can answer the call initially in that manner if you are near a connection.  iCall has not been officially released yet as an iPhone application, but it certainly looks promising.
Papaya – Papaya is a little bit of everything rolled into one handy application.  It’s part social network with chat rooms and games, an instant messenger, backs up your contacts and can act as a VoIP system.
PennyTel – PennyTel allows you to call other users of the service over Wi-Fi for free, or you can add credits to your account and you can call any number you want.
Truphone – Voted the best VoIP application by The Times, the New York Times, and Stuff magazine, Truphone is a free application that gives you £1 or $1 credit to get started with.  Works via Wi-Fi wherever you happen to be and supports calls to numerous countries.
WalkieTalkie VoIP – WalkieTalkie VoIP allows people to talk between PCs, Macs and iPhones without using a centralized server.  The reviews for this one range from “Great!” to “Horrific!”, so proceed with caution when spending your $1.99.

Web Based

Jajah – Log into Jajah, dial the person you are calling, and the phone number of a phone you can use, and Jajah will connect both those phones via VoIP.
PhoneGnome – PhoneGnome will allow you to call any of your contacts who also use their service, people using messengers like GTalk and MSN, or other SIP-based services.
Raketu – Raketu allows you to instant message, text and make low cost VoIP calls all from their Web interface.
RingFree – RingFree can work anywhere you get a cell signal and will allow you to make VoIP calls with all of your contacts from Skype, GTalk, Yahoo, AIM, MSN and also integrate with your company’s PBX phone system.
Talkety – Another Web app service that will allow you to enter the number you are calling, the one you can be reached at, and it will connect the two numbers together.

Combine Google Voice and Skype

Skype is a very affordable way to make long distance phone calls, but there is one problem with it: unless you set up a call display number you appear as “unknown caller” on the phone of the person you’re trying to reach. Many people will, assuming you’re a scam artist, and refuse to pick up.
You can buy a phone number from Skype to avoid this. Or, if you don’t want to spend money on a subscription, you can set up your Skype account to display your Google Voice number for call display. That way people you call will see a real phone number.
google voice app
You might consider doing this even if you’ve paid Skype for an incoming number: people will call you back at your Google Voice number instead of your Skype number, meaning you’ll get the call on all of your phones instead of just Skype.






Make Free Phone Calls Over Wi-Fi/Data Using Talkatone [Android & iOS]



In the future, your phone will only need a data connection. Paying for voice minutes and text messages will be an outdated concept and you’ll be able to communicate entirely over Wi-Fi. Google already offers free calls from your web browser, but they don’t offer this feature on smartphones to avoid upsetting the carriers. Talkatone does what Google won’t and offers free calls and texts over Wi-Fi.










Talkatone piggybacks off Google’s infrastructure, so it only offers free calls to the US and Canada. If you’re a Google Voice user, you can also receive phone calls and use text messages. Talkatone can even turn that iPod Touch, iPad, or Android tablet into a phone.

 Making Free Mobile Calls


Talkatone is available from Google Play and the Apple App Store. The screenshots here are from the Android app, but the app for iPhone, iPad and iPod touch is more mature and should work similarly. The free version is ad-supported. There’s also a premium version that removes the ads and offers improved call quality, among other features – but the free version works just fine.
Launch Talkatone and you’ll be prompted to add a Google or Facebook account. You’ll have to provide a Google account to take advantage of the free calls.
make free mobile calls

Outgoing Calls

You’ll see a dialpad after Talkatone connects. You can also use the icons at the top of the screen to select a number from your contacts, recently called list, or favorites.
free mobile calls
Placing a call is as easy as dialing the number. No further configuration needed!
free mobile calls
If you have never placed a phone call from Gmail’s web interface before, you may need to open Gmail in your web browser and place a single outgoing call before Talkatone will work properly with your Google account.
free mobile calls
You can also participate in VoIP calls over Google Talk or Facebook. Use the Contacts pane to start calls with your Google Talk or Facebook contacts.

SMS Messages & Incoming Calls

If you’re in the USA, read on – you can use Talkatone with your Google Voice account to send text messages and receive incoming phone calls. Talkatone has the features that should be built into the official Google Voice app, allowing you to use your Google Voice account entirely over a Wi-Fi or data connection. The How To screen under the Help menu will guide you through the setup process, if you need the help.
To receive incoming calls, log into your Google Voice account and enable the “Forward to Google Chat” option. You must also be signed out of the chat feature in Gmail.
free mobile calling
Talkatone runs in the background once you sign in with it, so you’ll get a notification when you receive a call. Place a call to yourself to verify everything is working properly.
free mobile calling
To get SMS support working, enable the “Text Forwarding” feature in Google Voice to forward text messages to your email. Once it’s enabled, you can send and receive SMS messages from Talkatone.

Status Message

By default, Talkatone advertises itself by adding itself to your Google Talk status message when you’re using it. You can change this – open the Settings screen, tap Accounts and tap the name of your Google account to customize your status.

Adjusting Call Quality

The Call Quality settings screen offers a variety of options to control call quality, with separate settings for Wi-Fi and cellular data connections. You can optimize Talkatone for high-quality calls over Wi-Fi and low-bandwidth calls over the cellular network.

Make Free Calls from iPhone With The Official Google Voice App


If you’re a long-time Gmail user, you no doubt know about and/or use Google Voice — a free web-based platform that provides users with an online phone number for making calls online via an Android, BlackBerry, and now the iPhone. If you don’t have a Google Voice number set up, you’re missing out on a very useful contact tool. Check out Ryan Dube’s 5 Cool Things You Can Do With Google Voice for more details.
I’ve been using my Google Voice (GV) number primarily as a second contact number for which family and friends can reach me when I’m a way from my phone and working on my computer. I also post the number on trusted website forums and registrations.

For a few months in 2009, a third-party Google Voice app was available for the iPhone, but Apple decided to remove it along with the official Google Voice app that was released a few months later. But now, the official app is back and available for free in the App Store.
google voice app

How It Works

In order to use GV on your iPhone, you need of course to have a Google Voice account. Once you’re set up, you will be able to use your provided number to make online phone calls, receive online voicemail, and make free calls and text messages to the U.S. and Canada, as well as make low-rate calls everywhere else.
After your account is set up, you can download the free app for your iPhone [iTunes Store link].
The app interface works similarly to the web platform. When you make a phone call using Google Voice, it first rings back the designated number of your iPhone and then it makes a call to the contact you’re trying to reach. You’re not charged by your carrier””in this case, AT&T.
Similarly, when someone wants to contact you using your Google Voice number, your regular iPhone number is called by Google, which in turn reconnects you to the caller if you accept the call. Your GV number is displayed as the caller ID when making calls, so the contact never sees or knows your regular iPhone number.
You can make phone calls from contacts in your iPhone address book or simply enter numbers on the dial pad.
google voice app

Forwarding Calls

I mostly don’t answer my Google Voice calls immediately. Instead, I have numbers forwarded to me via email. These emails will include not only the voice message, but also a written transcription of the message. The transcriptions are not always accurate, but they’re great for seeing phone numbers spoken in the message.
There are other call forwarding features you can do with Google Voice, but unfortunately you can’t do them on the mobile platform. See Mike Fagan’s article on how to set up call forwarding with Google Voice.

Notifications

If you want to be instantly notified when voicemail messages arrive in your Google Voice inbox, you will want to allow the app to send you push notifications, which means the app doesn’t have to be opened in order for you to receive notifications.
google voice app
Otherwise, you will have to open the app to find out what new messages were received.

Other Features

While the Google Voice app doesn’t provide you the ability to set your custom voice answer message or filter phone incoming numbers; it does allow you to star important messages, set up quick dialing for specified contacts, and view the history of your phone calls and messages — both received and initiated by you.
Google Voice is pretty easy to use and as long as the service is free, there’s little reason not to set up an account and use it. Hopefully, in future updates, Google Voice will be available for use on the iPod touch and iPad, just as Skype is. It shouldn’t be too difficult to set up the app as a VoIP/SIP dialer.
Also, note, there is a third-party app called GV Mobile+ [App Store link] that sells for $2.99. I have not used that app, nor do the features seem that different.
Let us know how Google Voice works for you, both on the web and via your iPhone or other mobile device.

Google Nexus 7 Tablet Review from PCWorld


Google Nexus 7 Tablet Review: Solid, but Not Revolutionary

The Google Nexus 7 tablet resets expectations of what an inexpensive tablet can and should be. Starting at $199, the Nexus 7 clearly guns for Amazon's same-priced but lesser quality Kindle Fire, which runs Amazon's limited flavor of Android. Make no mistake: Of today's 7-inch Android tablets, the Nexus 7 is the one to beat, and it is handily one of the best-executed Android tablets of any size you can buy. In some ways, that's not saying much; for as much as it does well—it has a tremendous 10-plus hour battery life, and it produces reasonably clear text and accurate colors—the Nexus 7 stumbles by leaving out an expansion slot. You need to step up to the 16GB $249 version for the Nexus 7 to make a sensible purchase, and even then you'll be settling short of the ideal tablet you really want.
The lack of a memory card slot hobbles Google's shiny new tablet before you can even get moved in and set up. Android has always held a big advantage over Apple's iOS in its ability to expand on-board storage via a memory card; in fact, this is something that every tablet competitor to the Nexus 7 but the Amazon Kindle Fire (and Apple's iPad, natch) has. The Kindle Fire has taken lots of flack for providing a baseline model with only 8GB of storage and no room to grow.

It's not clear why Google opted to leave out the card slot. Cutting it may be as much about Google's live-in-the-cloud philosophy and services as it is Google and Nexus 7 manufacturer Asus trying to meet an aggressive price. If it is indeed Google's emphasis on cloud services that's behind this choice—and likely that's the case, given that Google bills the Nexus 7 as being "Made for Google Play,"— that frankly makes Google's despotism no better than Apple's decision to keep users in its walled garden or Amazon's decision to force us to use its cloud services with Kindle Fire.
Amazon, too, tried to spin its minimal on-board storage by saying you could store media in, and stream content from, its cloud services. That approach is not rooted in consumers' real-world usage patterns, and it doesn't account for the vagaries of Wi-Fi availability and bandwidth. Consumers crave off-line storage; we're still away from a wireless connection often enough that local storage matters. No one wants to have to keep managing their content on and off the tablet just to work around a space limitation.
Given that we're seven months on from when Amazon's first-generation Kindle Fire was introduced, I'm surprised and disappointed that Google didn't push the default memory on Nexus 7 to 16GB in the $199 model. Now that would have gotten our collective attention, and rightly so. With Nexus 7 you're going to be downloading movies and television shows in high-definition, plus using apps optimized for high-definition displays and loading up your high-resolution images for use in the gallery, so 8GB just won't go very far. That amount of storage, with just 5.62GB of user accessible space when you first start the tablet--is just too parsimonious to make the Nexus 7 a truly solid recommendation. That's unfortunate, because the Nexus 7 actually gets a lot right—far more than most of its Android competition.

Nexus—Light and Comfy

When you pick up the Nexus 7, it's immediately apparent that it is not like other inexpensive tablets. Its construction has a high-quality look and feel; it doesn't have that inexpensive vibe you get from handling other "value" tablets in the market. The side bezel is plastic, with a textured, rubberized finish on the back that feels comfortable in-hand, and yet won't attract dust or particles as some rubberized backs we've seen (though it does seem to scratch fairly easily).
Another thing you'll notice right away: this tablet is light enough that you can hold it in one hand for extended periods. At 0.75 pounds, the tablet is still about 0.2 pounds too heavy for no-thought-required one-handed operation, as you find with the dedicated E Ink-based e-readers that now weigh under half a pound. Still, the Nexus 7 is among the lightest tablets we've seen, and more notably, it's 18 percent lighter than Amazon's 0.91-pound Kindle Fire. The Samsung Galaxy Tab 2 weighs about the same, at 0.76 pounds, and the Toshiba Excite 7.7 weighs 0.77 pound (with its 0.7-inch larger display).
The Nexus 7's footprint is about average. It's slightly thinner than the Kindle Fire (0.41 inch to 0.45 inch), and it's the same thickness as the Excite 7.7. The Nexus 7 is slightly longer than some of its competitors, too: it stands 7.8 inches tall, to Kindle Fire's 7.5 inches and the Samsung Galaxy Tab's 7.6 inches; the Excite is taller, though, at 8.1 inches. The Nexus 7 is also a smidge narrower than others, besting the Fire by 0.1-inch.
I find the dimensions of the Nexus 7 convenient and pleasing; at 7-inches, this tablet was unobtrusive to use in cafes or on public transit, and its dimensions made it easy to thumb-type on the on-screen keyboard in portrait orientation. Still, in spite of what the numbers say, I prefer how the Excite 7.7's feels in my hands; it seems more balanced, thinner, and lighter than the Nexus 7, in spite of the specs saying otherwise.
Other aspects of the physical design are noteworthy, too. The power/sleep and volume buttons along the curved right-hand bezel are sturdy and easy to press. Along the bottom bezel sits the headphone jack and a MicroUSB port, for charging the tablet as well as transferring data from your PC.
Above the ports is an approximately two-inch wide stereo speakers port (both speakers outlet from the same single port, as on the Asus Transformer Infinity TF700). The speaker location along the bottom doesn't seem to adversely impact audio playback; it could get covered by your hands if you hold the tablet two-handed in horizontal mode, but not if if you hold it along the bottom edge, as opposed to the center.
At the bottom left is a four-pin connector that Google says could be used for a dock, though no accessories appear to be available for the Nexus 7 at the time of this writing. Other hardware features include a 1.2-megapixel front-facing camera, and an NFC chip, which comes in handy for use with Android Beam if you happen to have another NFC-enabled Android device available.
The front face is smooth scratch-resistant Corning glass (but not Corning's Gorilla Glass). The glass is optically bonded to the 7-inch, 1280 by 800 pixel display, and this makes a tremendous difference in the image quality. With no air gap in play, text looks crisper, contrast is better, and glare is mitigated (although not eliminated). At 216 pixels per inch, the Nexus 7 is clearly way ahead of other 7-inch tablets' pixel density of 170 ppi, and the difference is palpable.
This is the third 7-inch tablet with a 1280 by 800 display. Oddly, Google appears to have tweaked the fonts in Android 4.1 and text rendering in the Chrome browser is very different than in the original Android Honeycomb (3.0) and Ice Cream Sandwich (4.0) browsers. The Nexus's tweaks lead to text that is visibly far superior to what we see on say, Galaxy Tab 2 or Amazon Kindle Fire, but is still sadly very jaggy and lacks the smoothness of "Retina" displays as on Apple's iPhone and iPad (which has 264 ppi), or even the smoother text rendering seen on Android 3.2 and Android 4.0 tablets. I'd have to say that Nexus 7's display bests that of Toshiba's Thrive 7 and T-Mobile's Springboard; both shipped last year with the same resolution display, but each had a noticeable air gap and produced poorer colors.
I am impressed with how Nexus 7 handled the test images in our image quality tests. Color reproduction is pleasing and fairly accurate, although Android appears to still struggle with accurately reproducing skin tones.

High Performance: Inside the Nexus 7

The Nexus 7 is the first tablet to use Nvidia's Kai reference platform. Kai was designed specifically to reduce the cost of producing a tablet without sacrificing performance. It would appear that the Nexus 7 achieves this goal, based on its performance on our tablet benchmarks.
Inside, the Nexus 7 carries a 1.2GHz quad-core Nvidia Tegra 3 T30L processor; it runs at 1.3GHz in single-core operation. Those are the same frequencies as found on the new Acer Iconia Tab A700, but Nvidia can't comment on whether everything about the Tegra 3 inside the Nexus 7 is the same as on the A700. The tablet also has 1GB of DDR3 memory.
The Nexus 7 lasted an astounding 10 hours, 10 minutes in our video playback test, with brightness set to 200 cd/m2 (candelas per square meter). That's just 36 minutes shy of the Apple iPad, and it tops all competing 7-inch tablets by a mile. Amazon's Kindle Fire lasted 6 hours, 54 minutes; Samsung's Galaxy Tab 2 7.0 lasted 6 hours, 20 minutes; the Toshiba Excite 7.7 lasted 7 hours, 32 minutes; and the Sprint ZTE Optik lasted 5 hours, 51 minutes. That figure is also competitive with 10.1-inch Android tablets; Acer's Iconia Tab A700 lasted 8 hours, 11 minutes; Toshiba's Excite 10 lasted 7 hours, 5 minutes; the Samsung Galaxy Tab 2 10.1 lasted 11 hours, 41 minutes; and the Asus Transformer Pad Infinity lasted 7 hours, 58 minutes.
Unfortunately, the Nexus 7 also took the longest of any 7-inch class tablets to recharge, requiring 3 hours, 49 minutes to fully juice up, compared with the Galaxy Tab 2's 3 hours, 32 minutes and the Toshiba Excite 7.7's 3 hours, 21 minutes. This result might reflect the fact that the Nexus 7 charges via its MicroUSB port.
The Nexus 7 excelled on our benchmarks. It was the best performer of any of our 7-inch class tablets; and was competitive on some tests with the top 10.1-inch Android tablets. Its performance on Geekbench, for example, was nearly four times better than that of the Galaxy Tab 2 7.0; and it bested Toshiba's Excite 7.7, too. Interestingly, though it was close to the Acer Iconia Tab A700 on this test, it outperformed the Acer on some of our metrics and fared worse on others. Both tablets run an Nvidia Tegra 3 at the same clock speed, so these variances could be due to tweaks in the Tegra 3 chip or other unknown variables.
On our two GLBenchmark 2.1.4 tests, the Nexus 7 was an average performer. It logged the sixth-highest score we've seen on Egypt Offscreen, at 63 frames per second; by comparison, Asus Transformer Pad Infinity logged 74 fps, and iPad logged 139 fps. On the Pro Offscreen test, the Nexus 7 was fifth highest, at 82 fps, as compared with 96 fps for the Infinity and 139 fps for the iPad. For perspective, the Kindle Fire lagged far behind, scoring just 23 fps and 31 fps, respectively, on Egypt Offscreen and Pro Offscreen.
The Nexus 7's performance on our Web browser-based tests was mixed. It was the fastest performer of our field on Sunspider, requiring just 1.71 seconds to complete that benchmark; but it was among the slower performers on a custom, media-heavy Web page load test.
In use, I found the Nexus 7 fast and responsive. I especially liked the dramatically improved keyboard, which seemed better able to keep up with my flying fingers.

Software: Jelly Bean Tweaks Android Again

The Nexus 7 is the first tablet with Android 4.1 Jelly Bean, and the differences between Ice Cream Sandwich and Jelly Bean on tablets are a lot greater than Google first let on. For my comparisons with ICS tablets below, I used Samsung's Galaxy Tab 2 (which also has a custom overlay), Asus's Transformer Pad Infinity TF700, Acer's Iconia Tab A700, and Toshiba's Excite tablets (7.7, 10, and 13).
The changes are evident as soon as you start up the tablet and see the Welcome screen. The new Android 4.1 Welcome screen and its ensuing setup walkthrough and first-time-use pop-up explanations are incredibly friendly for newcomers, with big, bold lettering and a clean design. That clean design continues with the Android 4.1 home screen, which reflects numerous changes to the Android experience on a 7-inch tablet.
For one thing, Google has refreshed the home screen with changes both minor and dramatic. A nifty Google launcher runs along the bottom, with five basic Google app icons--for Play Books, Play Magazines, Play Movies & TV, Play Music, and the Play Store--and a folder packed with 11 other native Google apps, including the Chrome Web browser which now replaces the previous "Browser" app. At the center of this launcher bar is the new menu icon, which is the only one of the seven icons that's fixed; you can swap out the others for other apps of your choice, or for folders of apps you choose.
Google has shaken up the design of its core navigation and status buttons, in order to reorient everything around the portrait position. Google expects 7-inch tablets to be used more in portrait mode than anything else. This explains the move of the three nav buttons (back, home, and recent apps) from their former location flush left to their new locale, spread out along the bottom center of the display. The clock and notifications, meanwhile, move from the lower right of the display to the top of the screen. To gain access to the notifications or settings, you must slide down the "shader" from the top of the display. After the clean simplicity of the notifications pop-up on the lower right of the screen, this new design is hard to get used to. Pulling down the shader reveals a larger clock, a rotation lock soft-touch button, and a settings shortcut. Though cleaner than the pull-down Google provided on the early Froyo-based Galaxy Tab, the effect is the same: It makes the Nexus 7 feel more like a phone than a tablet.
Other interface tweaks contribute to making the Nexus 7 feel more like a giant phone than a tablet. The home and menu screens are fixed in portrait orientation, which can be jarring if you're moving from watching a video to doing something else on the tablet. And in the settings menu, you no longer have panes in portrait mode; this change makes it faster to navigate among settings options. Also gone is the battery life percentage; you get just an icon now.
Many of these tweaks annoyed me greatly, since I was accustomed to the features offered on Android 3.x/Android 4.0 tablets; they made it more difficult to reach some features, and I prefer the simplicity of a tap versus a pull-down shader for accessing more menu options. Google says that the former layout should be what we see on future 10.1-inch Android 4.1 tablets, but I missed that design on the 7-inch size. I did like the new set of Play widgets for surfacing content from My Library, My Books, My Magazines, My Movies, and My Music, but I was less satisfied with the recommendations widgets. The beauty of Android is that you have the choice to customize the home screen, and you get customization in spades. Widgets are more resizable now; and in addition to the Google Play widgets, you get a handy new widget for quick access to wireless, rotation, and brightness controls--plus another one for using Android 4.1's new music identifier. The music ID worked successfully with most of the music I threw at it, struggling only with beat-heavy areas of dance tracks and some obscure world music choices from Croatia, Japan, and Poland.
At the top of the home screen sits the Google Now bar, with a handy introduction to the Google Now search services, and a microphone icon for initiating voice searches.
One more change for the better: The Google Nexus 7's native image gallery has improved image rendering as compared with Android 4.0 and 3.2. I noticed that images regained full sharpness more quickly than before, a critical feature when you actively use the gallery to show off your pictures.
Unfortunately, Nexus 7 also shows one of Android uglier sides--the pain of OS and device fragmentation. I encountered some tablet apps that wouldn't work on the Nexus, raising the old issues involving Android's app availability and compatibility. Android 4.1 goes a long way toward improving Android's usability--in spite of the aforementioned portrait mode and nav button mess--but it doesn't solve some of the underlying problems, either.

Bottom Line

Google succeeds at shooting Amazon's Kindle Fire out of the sky; the company has delivered a superior piece of hardware at the same starting price. The Nexus 7 also beats out the same-priced Samsung Galaxy Tab 2 (an Android 4.0 tablet with lesser performance and half the storage, but with a MicroSD card slot), and it beats out Barnes & Noble's limited Nook Tablet (which adds a MicroSD slot, but is restricted by B&N's custom Android version and the apps approved for it). I like the feel and design of the Toshiba Excite 7.7 better, but that model costs twice as much as the 16GB Nexus 7. Google hasn't positioned the Nexus as an iPad killer, but it's worth noting that the Nexus's price is a 38 percent savings over the cost of getting a larger-screen, same-size iPad 2, and a 50 percent savings over a third-generation iPad.
The Google Nexus 7 tablet is simply the best 7-inch tablet you can buy today. It performs well, but its mixed display performance and lack of a MicroSD card slot prevent it from eliciting unequivocal enthusiasm. Ultimately, the 8GB Nexus 7 is the best tablet you shouldn't buy today; although, that said, its relatively low price will soften the blow when you outgrow the Nexus 7's limitations and want to step up to another model in six months' time. At 16GB, the Nexus 7 becomes an affordably priced starter tablet that provides terrific battery life, solid performance, and the latest full-court version of Android. But beware of the storage limitations; they might be a deal breaker for anyone with a large media collection or a desire to download movies and TV shows from Google Play.
