Samsung Galaxy S7 volume turns itself down and back up on its own constantly

[AC Question]

I just got this s7 three or four weeks ago. Haven't dropped it from more than a few inches, there's a case, screen protector, etc.

I listen to a lot of pandora, and for the last few days while I'm listening to music, the volume will decrease to about half of what I had it set at for a few seconds, and then turn itself back up to the volume I had it set at.

After it got really annoying, i decided to try and narrow down the cause.

I've tried different headphones. The problem continues to happen, both on BT headphones and regular aux headphones.

I've closed out of all apps and only brought pandora back up. Didn't help.

Restarted the phone. Nope, no help either.

The last thing I tried was switching to the play music app to see if it was actually the pandora app, but it kept happening on the play music app as well.

Anyone experienced this or have any suggestions?

I've never heard of something like this, but here are some ideas to try:

Try to clear the cache partition:
Power Down the phone
Hold the Vol Up, Home and Power button at the same time and continue holding until you see an Android (Andy) mascot. Release the buttons and a menu will appear giving you several options. Choose the option to Wipe Cache Partition (careful as the one right next to it is to Wipe/Reset the device). Confirm and then reboot.

It almost sounds like when you get a notification and the volume adjust on your music for the notification, which makes me suspect an app you have. Try booting into Safe Mode and use the default music player and see what happens? If it doesn't happen in Safe mode, then I'd suspect a rogue app that is causing it.

Turn the device off.
Press and hold the Power key past the Samsung Galaxy S7 edge screen.
When "SAMSUNG" appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode

Another option (last resort) is for you to wipe/restore the phone and see if that resolves the problem.
