After a month or two, Sony rolled out ICS update for its flagship devices & subsequently for middle range devices. Now by fixing the bugs & issues like random lag & resource management, theyve pushed another ICS update with 6.1.1. But with Flashtool (firmware flashing tool for all Xperias), you can apply it to any unbranded / unlocked Xperia U worldwide.
As we all know that theyve taken a bit long time to release ICS updates, it may not be tolerable. Sony started upgrading Xperia U ST25i to ICS in September12. Android 4.0.4 ICS update has improved performance & stability over Gingerbread.
The status bar sometimes doesnt update the time, it's like but the status bar still shows the last i saw it, like time or something. if nothing happens try to set time manually with unmarked "Automatic" and then again marked with wifi on. If no luck, probably u need to do factory reset, remember to backup your data.
A.1.100 At first try just turn off and turn on the phone, then establish wifi connection and mark "Automatic" option in data and time settings Also check time zones.
We also noticed some significant performance improvements.
All these devices were launched with Gingerbread 2.3.7 on board (Xperia Tipo is exceptional).The problem is that the clock is synced, the clock app on the home screen always shows the correct time. As it is with leftovers, so it is with Android phones, or at least their manufacturers' willingness to expend time and money updating the software.Sony is also pretty liberal when it comes to bootloaders, so those with the inclination for root can try their luck with custom ROM scene.If you've still got one of these phones, it might be time for an upgrade anyway.if you have root install this and internet occasionally.
