Speaker Test & Mic Test

Find out whether your phone's speakers and microphone work. Open the app and start a test right away. There is no sign-in.


■ Left and right

- Play a short tone on the left channel, the right channel, or both.
- With headphones on, this shows whether each side works.
- On a phone with one speaker, both channels come from the same place. The app tells you so.


■ Earpiece

- Play a tone through the small speaker you hold to your ear during calls.
- The tone is quiet and short, and uses the call volume.
- Available on Android 12 and later, on phones that have an earpiece.


■ Frequency sweep

- Hold the slider to play any tone from 20 Hz to 20,000 Hz, or let the app sweep from low to high in 12 seconds.
- Listen for rattling or buzzing. The current frequency is shown in large numbers.
- Very low and very high tones are often inaudible on small speakers. The app says where that is normal.


■ Microphone

- A level bar moves as you speak.
- Record 5 seconds and hear it played back right away.
- Try the default microphone or the one used for video recording.
- The recording is kept in memory only. It is not saved to a file or sent anywhere, and it is erased when you leave the screen.


■ Result

- You mark each test yourself: you heard it, or you did not.
- The result screen lists each test with the date and your device model.
- Share the result as one picture, for example when you sell or buy a used phone.
- Check again and see this result next to your last one, for example after a repair or a new case.
- If something did not work, the app lists simple things to try first.


■ Good to know

- The microphone permission is asked only when you start the microphone test. Every other test works without it.
- The app shows where the sound is going: phone speaker, wired headphones, Bluetooth or USB.
- This app helps you check. It does not clean, repair or make anything louder, and it is not a hearing test.
- The level bar is a relative value, not a measurement.
