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.
