This driving me crazy I have checked every setting I can think of that would interfere with keeping the screen on while using the speakerphone option. It is as if the screen first dims which is normal but then it turns itself off and I must wake the phone up each time by repeatable touching the screen or side volume buttons. So far, I've tired changing the Always On Feature, Lock screen timer, AutoLock and a few other settings and nothing seems to help. Does anyone have any suggestions on how to fix this problem? Samsung Tech support is clueless to getting this resolved in fact I'm starting to suspect that they are intentionally ignoring this ongoing issue all together on their company support forum.
