Dear All, I am having this issue with my almost new phone:
The microphone works reasonably normally in other modes, but when the Z Fold 4 is closed and I use loudspeaker during a call, the other party experiences severe voice clipping, muffling and intermittent disappearance. Please specifically guide any solutions for the secondary microphone, acoustic openings, and speakerphone echo/noise-cancellation processing, to help address this issue which has become so frustrating.
