Anyone have a clue whats going on: I/m running 2.5.6 and cannot answer calls, this has been happening for 3 weeks or so. When I receive a call the screen blacks out and becomes unresponsive till the call is over, and functionality comes back. Same thing if I place a call, screen blacks out and becomes unresponsive to power button double tap everything. I thought it would be fixed with the OTA a few days ago, but nothing. I did a full wipe and nothing. Fresh install with gapps Banks dynamic. Any thoughts? Gonna flash stock.
