Android Phone Fingerprint Sensor Not Working - How Do I Recover Data?

Last Monday, when I tried to unlock my Android phone to make an important call, something strange happened.

The fingerprint sensor did not work, and despite thinking hard, I just couldn’t remember my unlock pattern. That momentary memory lapse led to multiple passcode attempts, ultimately locking my device.

If you have ever faced a similar situation, where the fingerprint sensor simply didn’t work for unknown reasons, you must have looked for some workarounds. Let’s understand what causes a fingerprint sensor on Android to fail and how to fix and access your Android device data in such a scenario.

Fingerprint Sensor on Android

The fingerprint sensor is a hassle-free unlock feature in Android devices that lets you unlock your device with just one touch of a finger. But what if it suddenly stops working, while you are trying to make a payment, buy groceries, or want to make an urgent call.

Why Fingerprint Sensor is Not Working on Android Device?

If your finger is injured, has scars, or is wet, the Fingerprint sensor may refuse to detect it, but I am sure you are past all that, and are here because the problem is recurrent. You may be dealing with a faulty sensor or a software glitch. Let’s understand some different causes in detail.

1. Damaged Fingerprint Sensor

The fingerprint sensor is the most delicate hardware on your device; it can get damaged with time because of dirt or dust, and refuse to recognize any fingerprint. This can happen if you've dropped your phone or exposed it to water.

2. Software Glitch

A software glitch can also stop the fingerprint sensor from working properly. This could be due to a problem with the phone's operating system or a malware.

3. Outdated Fingerprint Data

If the fingerprint unlock data has been changed without notice, the sensor will not recognize your print anymore.

4. Sensor Dislocation

If your device’s fingerprint sensor has shifted from its position because of a physical damage, it won't be able to read your fingerprint. This usually happens if your phone was badly dropped.
