same problem with differents head set …
i updates adnroid, no results

That’s weird. I’m also using FP4 with /e/OS but have never had the same problem with any of my headsets.
Which /e/OS version are you using?
Did you buy your phone from Murena? If yes, did you contact Murena support?
Did you ask on the Murena forum?
