How to fix your Bluetooth volume woes on the Galaxy S20
There are few things more frustrating than starting to listen to music on your new phone, going to adjust the volume, and then just being DEAFENED by the janky stairstep that happens when your Bluetooth volume is locked to your speaker volume, a feature called absolute volume. This has long been an issue on some Android phones, but the Galaxy S20 is the first time Samsung has shipped a phone using absolute volume enabled by default. Disabling this doesn’t take long, but you do have to unlock the Developer options menu to access it.
