I am using a Samsung Galaxy S2. The problem I am facing is that whenever I am connecting to data (internet) the phone is hanging frequently, getting stuck sometimes and even working very slow but when the phone is disconnected from the Net it is working absolutely fine. I am facing this problem from five days.
I have tried the following things:
Removed sd card, reset the phone, complete formatting done, but the problem remains.
So please guide me on how to resolve this problem.
