LG G5 Volume Instability

[AC Question]

I am on my 3rd replacement LG G5 (insurance due to faulty hardware each time) and each one has had the exact same volume issues. This is not regarding the Dialog box that says high volumes harm hearing. That I get very seldomly.
My issue is this: when I pause a song or video, or when I go to another app and right back, or allow screen lock to engage and then go back to the program/song, the volume sometimes is about half as loud. I did NOT adjust volume, hit the volume button, nor do the dialog box re: high volumes show up. It just randomly lowers the volume. And it won't fix itself unless I stop using it for a while or reset it.

What I want to know is there software built in to limit volume (besides the annoying a$$ dialog box), or is this fault of the manufacturer in either its software or hardware. The thing is, I can't find any solutions to this issue. This has happened to all 3, the 1st one I bought and the 2 replacements...

I am close to my Jump! so I may just say f' this phone and get a new one (def not LG)... But I am a few months off and this is getting to the point I want to just smash this POS phone...

There has to be someone else that has this issue... Heck, could it be an Android issue? My previous Androids did not have this issue...

Thanks in advance, Scott.

It seems exceedingly minor to me, certainly not enough to warrant a return.
I'll move the thread to the G5 forum to see what those guys may have to suggest.
