Raise to wake and notification animation issues

[alexgracias]

Hello, I'd be forever thankful to anyone who could help me with this. I have some issues with the raise to wake and notification animation functions. Every time I enable the raise to wake function it only stays enabled for a few hours until it disables itself on its own and I have no idea why that could be. Also when I turn on the notification effect 'light up screen when receiving a notification' the same thing happens, it works for a few hours and then turns itself off. The last thing I struggle with is the notification animation, but from what I've read, I'm one of many. Even though I read many tips and advices on how to fix it, it didn't help. Please, if anyone struggles with the same things or if anyone knows more and could help, I'd be very thankful!
