"OK Google" detection from any screen kills the alarm
Just in case someone else runs into this issue.
My alarm (default app) would get snoozed immideately after going off, thus becoming useless.
I have discovered that if I disable the "OK Google" detection from any screen
option, the alarm functions fine.
Hope it helps someone not to miss any important appointments.
