Screen turns black during call, but then won't turn back on?
On my AT&T Galaxy S4, when I make a call the screen goes black when my face is next to the phone. This is good.
However, when I take my face away the screen will NOT turn back on. If I hit the [Power] or [Home] buttons, it will sometimes turn back on, but often times it requires several presses or requires me to wait several seconds until the phone turns back on.
I've tested this on stock and several ROMs...
Does anybody else have this problem?
If so, how do I fix it?
