Onlyfun Old post, I know, but I wanted to chime in here, and say that I've noticed the same issue here. Turned off adaptive brightness, & set the screen to 100%, only to find out (when I REALLY need to see my screen in a hurry) that my 6A has turned the screen down to 70% brightness, & is completely invisible in the sun. Change it back to 100%, and next time I'm chasing shadows trying to see my phone, check the brightness, & it's been severely reduced again for no obvious reason. VERY frustrating. I don't care if it improves the life of my device, or gives it longer battery life, or even prevents blindness, because when I need my screen, I NEED my screen. Otherwise I love GOS. Hope this issue gets some attention, as a fix would be a great improvement overall. That's my 2ยข anyway. Cheers, Cotton
