I had put the "show touches" option in Developer Settings to ON and then i found out that sudden series of automatic 'touches' appear on the left part of the screen...vertically along the length of the phone...starting approximately from the left edge of the earpiece section. These sudden surges of quick automatic touches occur suddenly out of nowhere and causes havoc by opening & selecting unnecessary menus & options...
This is really scaring the **** out of me. I tried clearing Dalvik cache, cache, etc etc but i am having a gut feeling that this is a hardware problem.
PS: the phone was neither charging nor connected to PC.
Someone please help!
