I often accidentally trigger the sound player or the torch while I pick up or put down my phone from/to my pocket.
The phone is asleep when this happens, and likely I'm somewhat touching either the screen or some of the buttons, but I've no clue what I did exactly (and trying random stuff has been fruitless).
It's a OnePlus One running CM 12.1-20150418-NIGHTLY-bacon
.
What could ever be?
