Guys my M600 has suddenly gone hay-wire.

All of a sudden its touch screen stopped working. Some times it works but responds in a strange way and it is constantly calling numbers in my caller list by itself. Plz tell me what to do. Is it some virus or some other problem?

well go hurry take it up to SE care......

Connect to a pc and back up all files and contacts then do a master reset on the phone. If that doesn't work then it's a problem with your phone and needs to be taken back to the shop.

Could also try updating the firmware
