The fingerprint scanner on your Tecno Pova Slim 5G is designed to give you quick and secure access to your phone. But sometimes, it may fail to recognize your finger, leaving you locked out or forced to use a PIN or password. Fortunately, there are several ways to fix this issue and get your fingerprint scanner working again.
Why Your Tecno Pova Slim 5G Fingerprint Scanner Might Not Work
- Dust, dirt, or smudges on the fingerprint sensor.
- Wet or oily fingers that the scanner cannot read properly.
- Software glitches or outdated firmware.
- Incorrectly registered fingerprints.
- Protective films or cases interfering with the sensor.
Clean the Fingerprint Scanner.
A dirty sensor can easily cause recognition problems. Even small smudges or dust can prevent the scanner from reading your fingerprint.
Use a clean microfiber cloth to gently wipe the fingerprint sensor. Make sure your fingers are also dry and clean before trying again.
Re-Register Your Fingerprints.
If the fingerprints you added were registered when your fingers were wet, dirty, or at the wrong angle, recognition may fail. Registering them again with more care can improve accuracy.
- Open Settings, and then tap Security.
- Tap Fingerprint, and then delete existing fingerprints.
- Tap Add fingerprint, and then follow the instructions to register new fingerprints.
When registering, place your finger on the scanner at different angles so it captures a full scan.
Remove Screen Protector or Case.
If your Tecno Pova Slim 5G uses an in-display fingerprint scanner, certain protectors or cases can interfere with it. A thick or poorly applied protector often reduces sensitivity.
Remove the screen protector or case temporarily, then test the scanner again. If it works, consider replacing them with accessories designed for fingerprint compatibility.
Update Your Software.
Software bugs or outdated firmware can cause fingerprint scanner issues. Updating ensures you have the latest improvements and fixes from Tecno.
- Open Settings, and then tap System.
- Tap Software update, and then check for updates.
If an update is available, download and install it. Restart your phone afterward to apply changes.
Reset Fingerprint Settings.
Sometimes clearing fingerprint settings helps if the scanner has become unresponsive due to glitches. This resets the fingerprint system without deleting your personal data.
- Open Settings, and then tap Security.
- Tap Fingerprint, and then remove all saved fingerprints.
Restart your phone, then set up your fingerprints again from scratch.
If the fingerprint scanner on your Tecno Pova Slim 5G still does not recognize after trying these solutions, it could be a hardware issue. At that point, visiting a Tecno service center is the best option.
FAQs
Why does my Tecno Pova Slim 5G fingerprint scanner work slowly?
This usually happens when the sensor is dirty, your fingers are wet, or the phone’s processor is under heavy load. Cleaning the sensor and keeping your finger dry usually helps.
Can a screen protector affect the fingerprint scanner?
Yes. Thick or incompatible protectors often block the scanner from reading fingerprints correctly. Always use protectors designed for in-display fingerprint sensors.
Will resetting fingerprints delete other data on my phone?
No. Removing and re-registering fingerprints only affects fingerprint records. Your apps, files, and settings remain safe.
