Since the last update, I have experienced that when I connect my fairphone 6 to some headphones via bluetooth, the volume does not go up as before. The maximum is not loud enough. It happened with tow different headphones and I have tested both by connecting another tablet and they work perfectly fine; the issue is with the Fairphone. Has anyone experienced something similar?
Did you try deleting the two headphones from your Fairphone and pairing them again? Sometimes the Bluetooth volume gets disconnected from the phone’s volume, which can happen during updates (but also without). In those cases you can set the phone’s volume to maximum and the headphone volume can be controlled on top of that via its own controls. Re-pairing should fix that, so that setting the volume in the phone or in the headphones will set the overall volume.
