Automatic Resetting of Network Mode

[max010990]

Hello,

I purchased xperia go two years ago. It's now started giving problem. After some three to four hours, the NETWORK MODE option in Mobile Network automatically resets and then it asks for "change the network mode" and if i select any one option and if i press back button and then again enter in that Mobile Network option, its again showing "change the network mode" means none of the option got selected. Due to this issue, I am unable to access internet. Please guide me to resolve the issue.

Looking forward for your reply.

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

That sounds odd. I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:

If the behavior persists, I would advise you to reinstall/repair the phone software using PC Companion:

In PC Companion, press start on Support Zone > Start on Update the phone/tablet software > Press the blue link that says "Repair phone/tablet".

Before repairing the software in your device you may want to backup your information first. Check out this topic for more information on how to:
