Speaker Fix - Speaker Cleaner

Eject water from your phone speaker, measure decibels and test tones and stereo.

Got water in your phone speaker? Speaker Fix plays tuned low-frequency sound waves that vibrate the speaker and help push trapped water out, so muffled audio sounds clear again.

Speaker Fix is a free sound toolkit with four tools in one app:

WATER EJECT
• One tap plays a 165–500 Hz sweep in five cycles
• Progress ring shows each cycle as it runs
• Works after rain, a spill, the pool or the shower

DECIBEL METER
• Live sound level reading with Safe, Moderate, Loud and Dangerous zones
• Peak level and a scrolling history graph
• Reference levels for a whisper, normal conversation and loud music

TONE GENERATOR
• Any frequency from 20 Hz to 22,000 Hz
• Sine, square, sawtooth and triangle waveforms
• Quick presets and a volume control
• Handy for testing speakers, headphones and your own hearing range

STEREO TEST
• Play the left channel, the right channel or both
• Check that headphones and speakers are wired the right way round
• Spot a dead or weak channel in seconds

WHY SPEAKER FIX
• All tools are free on Android, with no ads
• No account needed
• Light and dark themes
• The decibel meter analyzes microphone audio on your phone in real time. Nothing is recorded or uploaded

TIPS FOR BEST RESULTS
1. Turn the volume all the way up before ejecting water
2. Point the speaker down so water can drain
3. Let all five cycles finish, and repeat if the sound is still muffled

Note: Speaker Fix helps clear water from the speaker grille. It does not repair water damage inside the phone. If your phone has been fully submerged, follow your manufacturer's advice.
