Since the last update, my S7's sound randomly lowers rapidly than cuts out.

[AC Question]

It cuts out randomly. The quickly lowers tell its mute and does it during games movies music and even the typing sound. It's getting really annoying. Sometimes it goes for a while without doing it but then it does it like every 2 seconds. Locking my phone and unlocking makes it work again for like 3 seconds and then it cuts out again.

Welcome to Android Central! Does it happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-28008. Or after a cache partition wipe? https://support.t-mobile.com/docs/DOC-24999

Another possibility is that the Vol Down button itself is faulty, and intermittently registering a prolonged press.
