Is it just me or is Ambient display much more reliable in 7.1? It doesn't seem to trigger by you just staring at it anymore.
I've noticed it is more aggressive at lowering the brightness than before. i actually find myself turning up the brightness more in certain situations.
On 7.0, I found that ambient display would often fail to activate when I picked the phone up after leaving it motionless for a long time. As if it was maybe affected by doze? On 7.1, it works perfectly no matter how long it has been since the phone was last moved.

That's not ambient display doing it. Its adaptive brightness. I have ambient display off and the screen is very dim when I turn on the phone after it's been face down.
