What the symptoms may tell you
Different apps and modes can use different microphones. If voice notes work but ordinary calls do not, the cause may be a setting, network or a particular microphone path.
Safe checks to try first
- 1Record a short voice memo and compare it with a video made using each camera.
- 2Try a call with and without Bluetooth or a headset connected.
- 3Remove a case or protector that blocks an opening and check app microphone permission.
What to avoid
Do not insert tools into microphone holes or assume that replacing one part fixes every call-quality problem.
Next step
Send the exact model and a list of which recording or call modes work and fail.
What I can help with
Microphone or associated assembly replacement is considered after model-specific diagnosis; board repair is excluded.
