Snooze sometimes does not work

[fracklaus]

I have the problem that in the morning when the alarm Clock rings for the first time, I cannot activate snooze. It only works if I unlock the device while the alarm is still ringing, then change to the nihhtdream app and touch on the screen. For after timeout of the snooze, the following alarm can be snooze normally. I also tried to set up a test alarm 15 Min in the future, activated the app and locked the screen --> alarm can be snoozed.

So this seems to deutend on the time the device has been locked, or on how often nightdream switched off the screen in the night. In a quick test I cannot reproduce it, but it fails reliably every morning when the alarm is ringing for the first time.

Device is a Samsung Galaxy Tab S2.
