Android P is  fixing its Bluetooth volume settings with an update that allow the mobile OS to remember volume preferences on a device-by-device basis.

It’s not a big change, but for someone who regularly switches between blasting music through a Bluetooth speaker and listening to music on a pair of headphones, it’ll be nice to not have eardrums blown out every time when switching between the two devices.
The update has already been approved and merged into Android, and still expected to be publicly released sometime this fall.
