Phone Speaker Not Working on Android? Fix It

Silent speakers are usually settings or dirt, not blown hardware. This ladder goes from the 10-second checks to a definitive hardware verdict.

1. 1Check volumes: press volume up, tap the slider expander, raise Media (not just Ring).
2. 2Disable Do Not Disturb and check nothing is casting/paired to Bluetooth (audio goes to earbuds silently).
3. 3Restart the phone.
4. 4Muffled/quiet? Clean the speaker mesh: soft dry brush, then our Speaker Cleaner tone to vibrate dirt/water out.
5. 5Run our Speaker Test, left/right tones give a definitive works/doesn't verdict.
6. 6Sound in headphones but never in speaker = speaker hardware; repair is inexpensive.
