Fingerprint sensor is not responding - you can do that

If your smartphone's fingerprint sensor stops working, there can be several reasons. In this practical tip, we will show you how best to proceed.

Dirty fingerprint sensor: Dirt is often the cause

As soon as your hands feel dirty, wash your hands - however, your smartphone is not cleaned as often. Dirt is probably the most common reason that the fingerprint scanner stops working. The following tips will help you with cleaning:

1. First, use a piece of tape to remove coarse dirt from the fingerprint scanner. Stick a piece on and press it onto the entire surface of the scanner. Then carefully pull the tape off again.
2. Take a piece of kitchen paper and dampen it with a few drops of water. Wipe thoroughly over the fingerprint scanner.
3. If you can still see residues, use a few drops of disinfectant on a microfiber cloth or kitchen paper and wipe them over the scanner. After a thorough wipe, this should remove even the most stubborn stains.
4. Then make sure that both your finger and the scanner are dry.
5. Now try again. However, if the fingerprint scanner still does not work even after thorough cleaning, it may be due to the following cause.

Unrecognizable fingerprint: Check your finger

Problems with fingerprint scanners can also be due to your fingers. Cuts, burns, burns or other changes to the fingers make the fingerprint more difficult to read.

So check if it could not be on your finger.

1. Add a new fingerprint to the system or use another finger that is already stored.
2. When you set up the new fingerprint, you will notice whether the scanner is still working or not. If he recognizes the touch and the finger is scanned when touched, then it works and it is due to the other finger.

Broken fingerprint sensor? Test the hardware

Various apps can be used on Android devices to test whether your smartphone's hardware is still working.

1. Download the "Test your Android" app from the Google Play Store.
2. Start the app and select "Fingerprint" in the menu.
3. Place your finger on the scanner. If the finger is recognized, this is confirmed. If a finger is recognized but it has not been saved, the message "Not recognized" is displayed. In both cases this means that the scanner is still working.
4. If you still see "Put your finger on the sensor" after placing your finger on the sensor, it is probably a hardware defect.
5. In this case, you should have your device checked and repaired by a specialist.

Defective fingerprint sensor: How to fix software errors

In some cases, an operating system error can also cause the fingerprint scanner to not work properly. You can try the following tips:

• Restart your device to fix any errors.
• Install the latest update on your device.
• If you have only recently carried out an update, you can try to restore the old version. Or you are waiting for the manufacturer to release a new update that can fix the problem.
• You can also try to reset the system. However, you should create a backup beforehand, otherwise all your data will be deleted automatically.
