my Galaxy S6 Edge plays media when the phone is on standby

[AC Question]

twice in the last two days, my phone is in my pocket turned off/on standby (not powered off) and then all of a sudden, I can hear audio from a video clip playing...could be unfortunate in a meeting or movie theater!

Put it in silent mode and make sure the media volume is off also. And lock your screen...
