When I get an incoming call the phone goes back to the home screen and freezes (won't respond to physical buttons or touching screen), it doesn't indicate that a call is incoming, I've been testing from another line. After a few minutes the phone will reboot. I've already done a clean boot. I've hit the reset button beside the SD card. I have set it to only use 2G and only use 3G. I have removed the SD card. Nothing seems to resolve the issue. I installed the 2.2 update several months ago. Yesterday it was in a reboot loop. Where it would basically alternate between the black screen with only "android" and the home screen (which was frozen). What else can I do? EDIT: I should also mention that the phone doesn't make any sound or vibrate.
