My screen on my Galaxy S6e keeps waking up

[AC Question]

Hi there, I have a Galaxy S6 edge, and my screen keeps waking up. I noticed this after I installed nova launcher, zooper widget, europa zooper, and a few icon packs.

It seems to be a notification, because there is a chime when it wakes, but there is no notification to be read or seen. I want to believe it's connected to the minute change, but I can't be sure.

Any ideas?

Try booting into Safe Mode, to test whether a third-party app is causing it.
