Sony Xperia U ST25A-WY Unlocked Phone with Android 2.3 OS and 3.5-Inch Touchscreen--U.S. Warranty (White/Yellow)

I got this phone for $160 from Amazon lightning deal and I am very happy with this purchase.Pros,Size: phone is small so it is very convenient to carry aroundScreen: screen is visible outside under sunlight. Touchscreen is very responsive.System upgradable: overall it is a good experience. It took me about 20 mins to upgrade. Although I did notice some 1-2secs lags after upgrading, that is totally acceptable for me.Battery life: for moderate-heavy use (call, text, web browsing and app downloading), my phone lasts me a day and a half, which is great. Note you can also buy a replace battery from eBay for around 10 dollars.Cons,The bottom LED light: it's a battery drainer although I like the idea. I have no idea how to turn it completely off.Storage: only 4GB available.Camera: speed is way too slow! It took like 3sec to turn on camera and 5sec to take a picture. I will never take pictures using this phone. Also I have no idea how the dedicated camera bottom worksOverall this is a great basic smartphone

I bought this phone unsure if it would work for me because everyone on here complains that it does not work with at&t. But as i mentioned before it is working with tigo in PARAGUAY (850/1900). For the price it is a pretty good phone, how ever it does have some lagging, especially after theupdate to ics. If you have money to spear i would recommend xperia p or s.

This is my first smartphone, bought to use with straight talk. Did not plan to do a lot of browsing. This fit my budget for a 2012-release phone and the Xperia phones have good customer satisfaction. It came down to the U or the P, which is a fair amount pricier but the same phone (processor) with more memory and an SD slot plus a slightly larger screen. ignored friend's advice that I get the pricier phone for the additional memory (he's a gamer), and so far I don't regret it. Lots of memory left ovcr for the several apps I have installed, and no need for an external SD card if you aren't into video or music. Even then, there's the Cloud if you have wi-fi. Reception is good and calls are clear. typing is definitely a little cramped on the 3.5" screen, but it has an auto landscape mode that makes it acceptable. If you are a texter or use a huge number of apps, the P might make sense. I'm good with thisUpsides: great price for the CPU and graphics. great look and feel. comes with a sony screen protector but no case, which is needed as it is a delicate little thing. would be a great phone for someone with delicate fingers, I get by. says you can upgrade to ICS but I have enough trouble figuring out 2.3 so until it is clear the upgrade is needed I'll stick with itDownside: battery life is limited. My old flip phone used to hold a charge for most of a week, and this one needs daily feeding, more if you leave the wifi on. I am sure the color stripe (which has no perceivable useful function and cannot be turned off) has some role in this, but a 1200 mA-hr cell doesn't go far . Wonder if it will accept larger cells.An excellent phone, would buy again. Comes with a 12 month Sony warranty in original box and shrink wrap. Nicer than the Motorola Atrix I demoed, despite having a slightly narrower screenAddendum: have seen other reviewers comment on damage to the phone. This is a fairly delicate plastic-body and screen phone. One would be foolish not to clad it in a case + screen protector. The Ecell case (available on Amazon for about $5) is really nice as a minimalist case, and will protect as well as make it less likely to drop the phone. There are also some beefier cases out there.Addendum #2" I wear Carharrt pants with side-leg cell phone pockets and even with the case, this phone fits in there like a glove. Try that Samsung S II

I bought this phone just a few days back. I like the look and design of the phone at this price point.However I got an error message "Emergency calls only" on the phone even when the network tower symbol is available on the screen.When i tried place a call it simply got disconnected without any response. I was able to make calls only after rebooting. I have noticed this issue a couple of times. The battery back-up is not good on this phone. I have made a few changes to overcome these deficiencies and continue to test this for couple of weeks because everything else is quite impressive about this set considering the specs and price.

Alright - the phone's specifications are good for a med-priced smartphone, the camera is powerful and unlike some other manufacturers, the phone is plug n'play, making file transfers quick and easy. Screen resolution is sweet.And that was my whole 1 hour experience with the phone.You see, after an hour, the phone gave me an alert that the battery had to charge. I put it to charge. After 4 hours the phone did not charge. It was dead. Went on Sony's website and tried to see if anyone else had similar problems (apparently I was not alone). The phonerefused to charge and refused to switch on. Sad really but I think Sony made a dud here. (I've had nine phones and ALL have been Sony's - they usually take ALOT of pounding and torture before failing).BTW - sent it back to Amazon and got a refund, no questions asked. Really, really good customer service, especially considering I returned the phone not from the States but from the Caribbean. On Amazon's part - really impressive (hence a star).I'll try another Sony phone though, the brand has been good in the past to me and one bad egg isn't enough to make me write them off completly. Another bad phone well....
