I have it on Android 6.0, but I do not have trouble with notifications. I do get the error quite rarely, like once per 2 weeks at most. It seems to happen when all of the following happen:
a) Phone is charging mode through USB
b) I exit using phone's "back" key and not going through the menus ingame to exit
c) I have been "alt-tabbing" a lot to check other apps as well.
The game has never crashed while playing.
