Fingerprint Test: Sensor Check

Is your fingerprint sensor working? Find out in seconds.

When fingerprint unlock stops working, the first question is simple: is it the sensor, or the settings? FingerPrintTest answers that with one button.

What it checks
- Whether your phone has fingerprint hardware at all
- Whether the fingerprint sensor is available right now
- Whether a fingerprint is registered on the device
- Whether your finger is actually recognized, using the standard Android biometric prompt

How to use
- Tap Start, then tap Start test
- Touch the fingerprint sensor when the prompt appears
- You see "Authentication succeeded!" or a clear failure message right away

Good to know
- If recognition fails 5 times in a row, Android locks the sensor for 30 seconds. Press Back and try again a little later.
- Nothing is stored. The app never sees or saves your fingerprint. Android does the check and only reports success or failure.
- No account and no extra permissions.
- Check whether it is really a sensor fault before cleaning, recalibrating or repairing your fingerprint sensor.

Ads
- The app is free and contains ads.
