My home button is whack and the volume buttons, the draining the battery works fine with me to use my phone again though when i leave my phone unused it goes to oblivion again over and over if leaved unused, idk what's going on but i somehow know when it has started, it started when my phone wont show the volume slider and i looked up for a fix to it and when i found one i deleted the apple.(something).plist and few days later this happened ,so i kinda hoping to find answer to it before deciding to send to the service.
