When I am running media such as music or youtube I pull down my taskbar or swap to a different app it turns my sounds down like I was in a call it lowers the volume and only uses the earpiece speaker, also when I connect Bluetooth devices for audio it I have to disconnect and reconnect the Bluetooth device 3 times before I get my phone to transmit audio to the device.
Lastly while I am writing to this post whenever I use autocorrect on Google keyboard it sometimes completely doesn't put the word down that i clicked on every time I tap Bluetooth this comes up - blueBluet.
I love the phone but currently the software is annoying me in some ways, even the autorotation needs some work.
I can see why Youtube will behave like that, but are you referring to the preloaded Music app or a different app?
All apps have the problem chrome the pre loaded music app and anything else.
It's always wise to test the phone in >>> safe mode as this will disable third party apps that could be causing issues.
