@Muessig When you put the phone on auto brightness is auto. there is no 'low, medium or high' auto.
@sinime that's my problem too, Its just to dark when not under sunlight for my enjoyment
This is not true. Do this, because I do all the time:
1. Go to brightness, and switch off automatic.
2. Change your brightness to low.
3. Switch automatic back on, and notice the vibrancy and brightness, even with automatic on (even while on automatic).
4. Turn off auto brightness, and switch it to high.
5. Turn on auto brightness...
See the difference? If you leave it on "low" with automatic still, your "default brightness" under normal lighting conditions are lower. If you leave it on high, the brightness is always a lot higher, but not to the point of being COMPLETE high like the setting without auto brightness. The cool thing about this is you can have the brightness on automatic+low during when inside, when you're in a normally lit room, but the sun readability still works when you're in the sun...
The iPhone does this too, where you can still slide the brightness bar, but automatic sensor still kicks in. Its a cool feature actually imo...
