Symptoms
- Callers say they can't hear you
- Voice memos or voice assistant don't pick up sound
- Video recordings have no audio
Likely causes
- CommonDebris blocking the microphone holeDust or lint covering the tiny mic opening muffles or blocks sound.
- PossibleLoose internal connector from the impactA drop can jar the microphone's small connector loose.
- CommonCase covering the mic holeA case that shifted after the drop may now block the mic port.
What to do
- Check that no case, sticker, or screen protector is covering the microphone hole.
- Test different apps — regular calls, voice memo, video — to see if the issue is app-specific or all microphones.
- Clean the microphone hole gently with a soft dry brush or a can of compressed air.
- Try a phone call on speakerphone versus normal mode, since some phones use different mics for each.
- Restart the phone in case it's a software glitch triggered by the impact.
- If no mic works in any mode after cleaning and restarting, it's likely a hardware issue from the drop.
