Fingerprint sensors have become a standard feature on most Android smartphones, making it easier for users to unlock their phones and protect their privacy. However, when the fingerprint sensor stops working, it can be frustrating and inconvenient. In this article, we will provide some solutions for fixing the “Fingerprint Sensor Not Working” issue on Android devices.
1- Clean the Fingerprint Sensor
The first and most common solution for a malfunctioning fingerprint sensor is to clean it. Use a soft cloth or tissue to clean the sensor gently, as dirt, dust, or oil can prevent the sensor from reading your fingerprint correctly.
2- Add a New Fingerprint
Sometimes, the sensor may not recognize your fingerprint due to changes in the way you use your phone or if you have recently injured your finger. In such cases, you can add a new fingerprint to the phone’s memory. To do this, go to Settings > Security & location > Fingerprint > Add fingerprint.
3- Restart Your Phone
Restarting your phone can sometimes fix any glitches or issues that may be preventing the fingerprint sensor from working correctly. To restart your Android device, press and hold the power button until the power menu appears, then select “Restart.”
4- Update Your Phone’s Software
Updating your phone’s software to the latest version can also fix any bugs or issues that may be causing the fingerprint sensor to malfunction. Go to Settings > System > System update and check for any available updates.
5- Remove the Screen Protector
Sometimes, a screen protector can interfere with the fingerprint sensor’s functionality. Try removing the screen protector and see if that fixes the issue.
6- Clear Cache Partition
Clearing the cache partition can sometimes fix any software-related issues that may be affecting the fingerprint sensor’s performance. To clear the cache partition, turn off your phone, then press and hold the power button and the volume down button simultaneously until the phone boots up. Then, use the volume buttons to navigate to “Wipe cache partition” and select it using the power button.
7- Reset Your Phone
If none of the above solutions work, you can try resetting your phone to its factory settings. Before doing this, make sure to back up all your important data as resetting your phone will erase all data on it. To reset your phone, go to Settings > System > Reset options > Erase all data (factory reset).
The “Fingerprint Sensor Not Working” issue on Android devices can be frustrating, but it is usually solvable by following the above solutions. Try each of them one by one, and if none of them works, contact your phone’s manufacturer for further assistance.
