Hello, there is a typing mistake in the settings menu under setting 'App-Control' and then under Bluetooth and then press the questionmark on 'AVRCP metadata (HACK)'. You'll see the text: "Devices running Android 5+ shouldn't user or need this." The typing mistake in this sentence is the word 'user', it should be 'use' I think. I'm from The Netherlands but I'm pretty sure I'm right.
