I feel sort of weird repeating the title of my question verbatim, but...Every so often, the volume on my Samsung Galaxy Note 5 will oscillate wildly. How do I make that stop? Preferably in a way that doesn't just paper over whatever's actually causing the problem.
Rebooting will at least make it stop in the moment, but I'm averse to this because I tend to accumulate things that I want to keep open that die on reboot, and because it's a temporary solution at best.
I have not successfully found circumstances that reliably reproduce this behavior, but it tends to happen roughly every couple of months, I think, and I don't think it has lasted more than 15 minutes (though I don't know if this is because I've just never let it keep going or if this is actually useful information on how long this will keep happening if left to its own devices).
I have an Otterbox case on the phone, and as far as I recall this phone was the current model when I got it.
I'm not sure if "my headphone jack doesn't have a good connection (i.e. there's static sometimes and it can end up disconnecting if the cable rotates in its socket)" is useful information, either, but I thought I'd mention it just in case it is.
