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.

- 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.
