SWITCHING OFF

[TaniK]

Im having troube with me sony xperia arc s since i updated the software via pc companion.

Whenever I click on anything on my phone in a matter of seconds it takes me back to the homepage! I went on my browser and waited for my page to load and finlly when it did it just took me back to the homepage. Same thing happens when playng a game it wont even load and it takes me back to my homepage! So annoyed!

Also when going on settings it says I have enough memory available (124 megabytes) but when it comes to installingg an app it says there is insufficient space on your device. If I try again on another day theres a possibility that itl install.. doesnt make sense 

PLEASE HELP

Try performing a system repair as this will often fix issues after an upgrade - This will factory reset your phone

Switch off your phone 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 phone 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
