Since I upgraded yesrerday on my Att note 4, my autobrightness keeps resetting while I am reading. I turn off the autobrightness, but 5 minutes later my screen will dim again, and it is checked again. I checked power saving mode, and it's not on, cleared my cache, and turned the phone on and off. It was bad enough when my phone decided that full volume, even on bluetooth was going to require an extra step, but not letting me pick how bright I want my phone is seriously pissing me off.
