amir_sp, 31 Dec 2013downgrade to it's original firmware and it will be ok. Is it possible to downgrade ?
The only problem in Xperia u is the external memory otherwise it is the best phone for low range androids phone
I dont understand the complaints about battery, my Xperia U has the best battery of all smartphones i had, it can last 3 to 4 days on normal usage, and easily lasts a day of somewhat heavy usage.
The problem is wifi, it drains enormous amounts of battery juice if wifi is kept on during standby and will just barely last the day, so i recommend to turn on Extended Standby Mode, or use the quicktoggle widget to turn off wifi manually for even more battery saving. If you are a 3G mobile internet user then Xperia U is an extremely good phone since the wifi drain issue will not bother you anyway plus HSDPA is usually faster than wifi, a win-win situation for this phone.
My U is stable and reliable, no crash, and no hang except when using Chrome browser - i have to use the default Android browser to get smooth browsing.
Very satisfied Xperia U user here, i came from a high end quadcore 1080p phone and was planning to get a new high end phone again soon but im so satisfied with the U that i may cancel my plans to buy Xperia Z1 Mini.
many times it slips from my hand but never breaks it never hangs the loudspeakers are not so loud the batery charge up quickly but at the same rate it discharage overall a good phone
it's handy and pocket sized.
i'm satisfied with this phone...i surf the net,use apps...
since i bought xperia u I don't use my laptop.
but i have to say it has some disadvantages
1.when u answer ur phone it takes some mil-seconds to respond.
2.It has a small display for reading or surfing the net but the small size has positive point to do ur works in ur bed with one hand(seriously good point,u would never understand it unless u try it)
3.it becomes laggy by the time u use it more and install more apps
4.when u upgrade xperia u it gets lag.
5.u have to charge it every half of the day if u work with it 4 hours(surfing the net with data turned on)
best mobile ever i use if battery time will increase their will be no match of experia
Terrible phone, extremely laggy after ICS update. Mine is so slow and crashes so often the battery cover is loose, so many times I remove it to unfreeze it. Some calls are impossible to answer, the time for the button to show is so long the calls go to voice mail. Others don't even have time for showing person name or image. I've reseted my Xperia U more than a couple of times in a year, and a few time latter it's lousy again.

Guys, Xperia U - ST25i is best for video clarity as it has 280 PPI and sound is awesome (better than iPOD quality). Its stylish look makes you proud. But It hangs all the time if you load it with more apps..
