Recorded audio is very quiet and sounds muffled. In-call audio is the same, but can be fixed by turning the speakerphone on. People in calls consistently say they can not hear me, and it is solved every time by turning speakerphone on and comes back when speakerphone is turned off. Is a different mic used when speakerphone is on? How can I force the phone to use the speakerphone microphone settings all the time?
