Ever since I updated my Samsung S2 the other day my S2 has been turning itself off and sometimes the power button and home button become unresponsive. When it turns itself off the actual phone feels warm, like my iPhone used to when it was using some power draining apps. I have the power save mode and etc so it uses less power but it still turns itself off after a while. Is there anyway to roll back the firmware or is the problem something else?
Yesteday I tried to access the WiFi settings in the menu and the screen went black for about 30 seconds and then said an error occurred and to force close the wifi settings and sometimes the screen freezes a bit.
