But when i put that sim to another phone and data card it was working fine.
Then i switched off 2G then everything working correctly fine.
So i shown it to service center and they said initially that phone is fine.
But problem is still there so is any one there who can help me.
I tried everything.
First of all, you just review the applications you installed when the problem started. If any remove those and see to it. Still if the problem persists, try a factory reset. Still if you cannot rectify it, flash with the stock firmware, if u know to do it, or carry it to service center and ask them to flash with the stock OS, if u are under warranty, you can demand it to them, its your right. And still the problem exists, argue with the service center personnel to get it repaired and prove its okay, the way you want it
