    Vital Statistics

    The Xperia U weighs 3.88 ounces and measures 4.41 x 2.13 x 0.47 inches.

    Android Gingerbread Operating System

    Android Gingerbread

    The Xperia U runs the Android 2.3 operating system (dubbed Gingerbread). It features a cleaner, more refined interface with new icons, improved top notification bar, and more intuitive navigation.

    Multitasking in Gingerbread allows you the ability to run more than one app at a time. If you're playing a game, you can easily switch to an incoming e-mail and then switch back to the game without losing your place. And like the previous version of Android ("Froyo"), Gingerbread provides support for Adobe Flash Player 10.1 for access to the full Web.

    A new onscreen keyboard makes it easier to type thanks to additional spacing between the keys and larger font sizes. And the more you use the keyboard, the easier typing will be as the enhanced suggest feature records previous input history to make better suggestions.

    The Xperia U also brings one-touch access to the popular Google mobile services you use every day. It also provides easy access to both personal and corporate e-mail, calendars, and contacts supported by Exchange Server and Gmail. And through the Google Play store, you'll get access to thousands of useful applications, widgets, and fun games to download and install on your phone, with many more apps being added every day.

    Google Integration
    • Google Play store for browsing and downloading thousands of free and paid apps

    • Google Maps Navigation with spoken turn-by-turn directions showing real-time traffic and 360° views of the destination

    Unlocked Phone

    This unlocked cell phone can be used with a GSM network service provider. It does not come with a SIM card, and it requires that you provide a SIM card for usage with your selected service provider.

Sony Xperia U


The Sony Xperia U is an entry level Android device at a very reasonable price point of $219 (Although I find the price constantly fluctuating on Amazon). Keep in mind, if it's not already clear to you now, that this is a very small/thin phone. Using the iPhone as a reference, the Xperia U 3.5 in display is NOT like the iPhone's 3.5 in. Xperia U's display is taller but thinner (considerably so, which you'll notice when the keyboard comes up and how tiny certain icons such as battery, service bar, and general font), which still satisfies the 3.5 in, but keep that in mind when purchasing (I personally like small phones, not into the whole mini-tv in my pocket kinda thing). The phones I've owned in the past couple years are the Droid Pro Plus, Mytouch 4g, Blackberry Curve, Mytouch 3g slide, and the original iPhone. This is to help give the reader a sense of where I'm coming from and what I'm comparing to. I really enjoyed the Droid Pro Plus, which was my last phone before this phone, but I sustained a little bit of water damage on a hiking trip so I figured I'd try something new. I'm pretty picky, so the things that bother me might not bother you, but here goes:


1. Fast
a. The phone is very responsive with the Dual-core 1 GHz processor
b. Very little lag overall. Using Angry Birds as the reference, cuz everyone's played Angry Birds, there's slight choppiness with the background enabled in the game but it's perfectly smooth with it disengaged. It's never really stalled even with background enabled, only the FPS has dipped a bit and it's a bit noticeable, but other than that no issues.
c. Browsing with the phone is also a nice experience (in regards to speed).

What a great phone, I was looking for something new, modern, fun, elegant, and sophistic.
This is the phone, its actually and medium end device by the new generation of Sony smartphones, but this is one is what great for anyone looking for something catchy, durable and well made. Sony created a phone no so expensive like the others brothers from same family, this one has what you need on any smartphone, It will keep updated and you will be able to do all you need on today world.

1- Is fast and works smooth on any application
2- Ready to be updated to new android is fantastic, no bugs no problems at all.
3- Has an interesting durable, fancy and resistant material on case, looks good, feels good.
4- The screen has everything you need, bright, deep contrast, great sutured colors, HD. Not really great for finger prints marks but is very resistant for scratch... If you buy some screen protector you dont have to worry for dust or finger prints.
5- Yeap I know just 8 gb internal memory, but thats enough for apps music, HD Photos and more, not a bad thing.
6- The camera works great and does the job not really fancy but what you need for you phone at any good moment.
7- Very sensitive at touch works fast.
8- Very personalized, the light on the bottom and the changeable cap is very cool.

UPDATE ( August 22, 20 days of use)

The phone is amazing, after all this time, I have no complains about it. No bugs, No problems.
I want to add something about the battery, this phone has a battery Standard battery, Li-Ion of 1320 mAh (not a big issue), don't know why they didn't put something better, but is ok, if you install some apps like: Defender Juice and specially Easy Battery Saver, any android phone will last longer, like twice the time.

Awesome phone, great speakers and it has the Xperia Sola quick text typing (just move the finger through the words and the phone deciphers what word you want to spell) is a real attention grabber. Although you have to charge the phone every night because the battery runs off quickly.

I'm a tech geek and have used many mobiles over the years. I've used Palm, Blackberry, WinMobile, Webos, Ios, Meego, WP7 and Android. So I know the differences. Having used many of them, I have made Android my primary phone. The reasons for me are simple - I like to be in charge of my device. Customization is a choice, it is not mandatory. Many iphone owners will say oh you have to tweak your Android phone to make it useful. Nothing can be further from truth. It is entirely up to the user. There are many cool things you can do with Android that you never can on any iphone.

- A proper file manager/USB storage: what is it and why it matters? If you used any USB flash drive, you know how it works. You just plug it in and it shows up as a drive and you can drag and drop ANY file in it. Android works the same way. There is no special itunes/zune-like software you need to manage your phone. It's sad that Apple charges so much for higher capacity iphones yet the storage can not be managed in any way YOU please. It's strictly designed to be a consume devices - music and video.

- "AirDroid" - simple and free app for Android that allows you to do nearly everything from a browser interface without even touching your phone. this includes file transfer, app management, send/receive txts and much more. this is very convenient because you can have your phone in your pocket.

- "mysms" or "mighty text" - these are also handy as they allow you to send/receive sms without even touching your phone as long as your phone has working signal. pretty awesome in office environment.

Mind you, 90% of Android customization can be done by anyone irrespective of tech knowledge. There is no rooting(aka jailbreaking in Ios world) needed.
