I have tried to test this over many nights/iterations.
Whenever the alarm goes off it shows 2 options on the display. "zzz" for snooze and turn off alarm.
When touching the "zzz" part of the screen it will not vibrate again.
I have tried to be precise with the touching and not potentially touch the main menu button which I suspect would do the same as just turn the alarm off.
What can I do?
