unfortunate, but no surprise there ¯\_(ツ)_/¯
I installed UT20.04 on my Fairphone 4 (which is waiting for waydroid for me to make the switch) and that works for music. Even BT multipoint works between the Momentum 4, FP4, and an ubuntu laptop :party_popper:. not sure yet about calls on any of them.
@muskist
No, it clearly identifies the headphones as "MOMENTUM 4" and claims to be connected, but without signal strength
@RedXXIII
I don't have any other bluetooth devices to test this with, but at least I can confirm music working on a FP4/UT20.04.
