Hello 

I have s20+ and a very low sound volume during phone calls. All volume setting are on max. The volume other bluetooth (headphone or auto) ist normal and loud enouth. Only the inbuild phone call speeker is this way quit. The Samsung online support indicated the hardware defect on the speaker.

I have replaced the phone and got the new one. Directly used it after initial setup - good, loud sound from the phone speeker (calling, not the media-speeker). Then I connected it with my car via bluetooth. And after that (disconneted from the car)  the same problem with the  second s20+.   No siginficant changes made. All volume setting are on max. The call speaker sound has became low.

A hardware defect can be IMHO excluded, after the second new s20+ has the same behaviour.

Does somebody know about this issue and how to handle it?
