3. Ensure your phone screen is clean

If your phone’s screen is dirty, it can interfere with the fingerprint sensor and cause it to malfunction. Make sure the screen is clean so that the fingerprint scanner can properly read your fingerprints.

4. Enable touch sensitivity

Certain screen covers, including fingerprint sensors, can reduce touch sensitivity. Turn on touch sensitivity and see if it solves the problem.

Here’s how to boost your touch sensitivity:

Open Settings
Then tap on Display
Next tap the Touch sensitivity and toggle the switch On

5. Remove and add new fingerprints

Because of wear and tear and other circumstances, your fingerprints may alter over time. Remove your old fingerprints and then rescan new ones. Do not push too hard when rescanning your thumb. Simply lightly touch all sides of your thumb. This will enhance fingerprint recognition.

Method for removing old fingerprints:

Open Settings
Scroll down and tap on Biometrics and security
Tap on Fingerprints
Type in the PIN, Password, or Pattern if prompted
Select the fingerprints to remove. To select all, touch and hold a fingerprint then select All from the upper-left corner
Tap on Remove (top right corner). Then confirm to remove the fingerprint(s)

Procedure to add new fingerprints:

Go to Settings
Tap on Biometrics and security
Tap on Fingerprints
Type in the PIN, Password, or Pattern when prompted
Tap Add fingerprint. Enter the current PIN, Password, or Pattern if prompted
Follow the on-screen tutorial to scan your fingerprint
Tap Done to add the fingerprint

Before starting with the new fingerprint registration, make sure the screen protectors are removed from the phone and your fingers are thoroughly cleansed.

6. Update software

If a bug is causing the fingerprint scanner issue, updating the software may help. Follow the steps below to check for and install software updates.

Go to Settings
Tap on Software update
Then tap on Download and install to download and install the update.

7. Wipe system cache partition

A faulty or broken system cache can cause fingerprint sensor difficulties. To wipe and rebuild the system cache partition, follow these steps:

Turn off your phone
Connect your phone to the PC via USB
Wait until the message shows your phone is being charged
Press and hold the Volume Up key and the Power key.
Continue to hold both keys until Android Recovery menu options appear
Press the Volume down key and navigate to Wipe cache partition
Click Power key to select
Press the Volume down key to highlight Yes, then press the Power key to select
When the process is complete, Reboot system now is highlighted
Press the Power key to restart the device

8. Factory reset the phone

If none of the aforementioned alternatives work, you can try factory restore as a final resort. But, before you do so, make a backup of all your vital data and files, as the method would entirely destroy them.

To perform factory reset, follow the steps below:

Go to Settings
Tap on General management
Click on Reset
Tap on Factory data reset
Scroll down and tap on the Reset button
Tap the Delete all button to proceed with the reset

If you are unable to access your device, you can use another technique to conduct the reset. Here’s how to go about it.
