Yes bro it started again ... do you think installing firmware or falsh will solve this problem...plz reply as i ll go to service centreYour phone seems to have malware. You must do a fresh install of firmware on your device to get rid of this issue. If you are not aware of this process, take it to the service center and they can clean flash the firmware for a nominal amount. The steps you have taken might have resolved the issue temporarily, however the malware might still be there and there are serious things Android malware can do!!
