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.
