Lt30p automatically reboots

[screepture]

I have had my lt30p for a while and recently it started rebooting automatically, mostly when my charger is not plugged in or my network seems to fluctuate....is it a cellphone network thing that is causing the reboot or do i need my phone repaired?........secondly how do i get my phone refurbished? I have had it for a while and would like to have it for a little longer...

Try removing your Sim and SD cards and testing as this type of issue is normally associated with faulty cards

At this point I can only advise that your perform a system repair and if that fails then you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/

Performing a system repair using PC Companion - This will factory reset your phone and erase all data so best to backup before you begin

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 on screen 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
