how do you set the percentage or do you just have to guess?
100% all the way. anything less looks way too dark
I always keep auto brightness on, but it never seems to adjust or do anything. Could this possibly be because of my case or screen protector?
Was wondering how high you keep your screens brightness? I'm wondering if the majority have it at full level or keep it at around midlevel like me to conserve battery
Does it take a second or two for the brightness to auto-adjust? That's what seems to happen to my iPhone.It only adjusts the brightness when you "slide to unlock." Once you've done that, and start using the phone, the sensor turns off (no longer adjusts the brightness).
