The microphone on my Samsung S10e sometimes stops working during call, and the caller (whom I can hear perfectly) can no longer hear me. This occurs intermittently (i.e., not on every call), whether the phone is in or out of its folio-/wallet-style case. The issue is binary -- the quality of the audio is clear, it just occasionally shuts off; toggling to speakerphone does not resolve it. I also tried a force stop of Bixby Voice and Dictation then a hard power off/on. Any other ideas?
