AOD on Galaxy S7

[Android Central Question]

Is it normal for the AOD to not come on when I turn my S7 off at 4% battery? It came back on after I plugged it in.

Some features are disabled when your phone hits 'critical battery' for obvious reasons; AOD is one of them. I believe the flash on your camera, for instance, will stop working if you hit 20% (or is it 15%? something like that).
