Developer-Dude Weird, perhaps it is something trivial like being the button 'stuck' once in a while, perhaps caused by dust or a hair or whatever once in a while, maybe 6a's are prone to it being 'stuck' once in a while? If so u probably will find some more reports about it on the net.
I must say i admire your memory!
Developer-Dude It did once yesterday and once a few months ago
Being able to remember all this on those 2 pretty separted occasions is strong!
Developer-Dude it is audio in general. Audio in Vanadium, NewPipe, Gramophone, etc. Happens when playing on the phone speakers, Bluetooth speakers, headphones and earbuds (both wired). Even if I try to adjust the volume on the home screen its done it before.
Nevertheless, thank u in advance for providing feedback if u come across something regarding this to potentionally help someone else arriving here in the future.
