lose of settings

[chrisgarbett]

HI. All, I've just had my tablet. Back from Sony after repair and they updated my software and now my settings won't save. It keeps reverting back to the original settings. For example screen timeout keeps going back to 15secs. I change to 30mins. Also mobile data keeps turning off. Very annoying. Anyone know what's the cause please. Thanks

Try to perform a system repair and if that fails contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/

Switch off your tablet and unplug from Pc (Hold volume up and power for around 10 seconds)

Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your tablet still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

I also get screen flickering since I've had it back. What have they done.

Screen flickering has been an issue since all the upgrades have taken place.  The only version that is STABLE is the original one 4.1.2 that the tablet was designed around.  I am fortunate to have two tablets and one has remained at 4.1.2 on purpose while the other one keeps getting upgraded.   4.1.2 is VERY stable.  Sigh...........
