Keep the screen on while im in a call? This isnt a huge problem but its a little irritating. I know just hitting the power button turns it on but its a pain in the ass when the call ends and my phone dies bc im too slow to turn the screen back on and hit end. Itd be nice if i could just keep it on during the whole call. specially when i call my voicemail. is there a way to do it? cause ive looked in the settings and junk and couldnt find anything.
