However, it can also be really annoying when TECNO fingerprint is not working, especially when you are used to it already. If it does happen, there is no need to panic. The first thing to do is to check for the most commonly reported issues with fingerprint scanners and try to fix them.
In this article, we will cover several common issues and discuss what can be done to fix TECNO fingerprint not working so that your phone can be back to normal as soon as possible.
Part 1. TECNO Fingerprint not detected
If your TECNO phone fails to detect your fingerprint, it can be that the sensor surface is dirty or wet, scratched, damaged or there is an error with the fingerprint software.
Method 1. Fixing a Damp or Dirty Scanner Surfaces
With use, the scanner surface can pick up dirt or become wet with exposure to water. If this is the issue, ensure you wipe the surface with a cotton swab using alcohol or methylated spirit as a solvent. Wipe the surface dry with the swab and test the fingerprint function once this is done.
Method 2. Fixing a Damaged Fingerprint Sensor
The fingerprint sensor will not work well if it has become scratched or damaged. To fix this, book a Carlcare service reservation and get your phone fixed asap. You can also check the warranty for your TECNO phone before you go to service centers.
Method 3. Fixing a Software Error
Most TECNO phones come with periodic system updates. These system updates usually include bug fixes and additional security patches to keep your phone safe. Failing to upgrade your firmware from time to time can lead to a system error.
To fix this, simply update the entire system or software as the case may be. Ensure your device is fully charged or plugged in before an update. Do not continue if the battery percentage is below 40% as you may not be able to complete the process and an incomplete update will also result in several issues with your device.
Part 2. Fingerprint not recognized
Maybe your phone even detects the fingerprint but then, it does not recognize it ? It can be that you have used a wrong finger or multiple fingers at the same time. At other times, it could be that the app cache is full.
You have used a wrong finger if you use one different from the one you earlier saved. Once you have saved a particular finger print setting, always use that finger to carry out the earlier specified functions. Most TECNO phones allow you to save more than 3 different sets of prints so we advise that you do exactly that. Having such multiple options helps.
Method 1. How to Add or Delete Fingerprints
Depending on your particular requirement, you may need to add new prints or delete old ones. Here is how to do just that
- From The Main Menu, Navigate to the Settings icon and select it..
- Scroll to security options and click on it.
- Find the Fingerprint management function under the security tab and open it
- Click add to create a database of new fingerprints. Ensure you save the fingerprints from multiple finger
- Select the functions you want to use the Fingerprint function for. This may vary depending on the particular TECNO brand but will likely include Unlocking the phone, Taking photos, Call recording, Accepting calls, Dismissing alarms etc
- Save the options and you are good to go.
- To delete already saved fingerprints, click on the three dots beside the fingerprint and in the pop-up, select delete.
Method 2. Clearing Cache
If the app and cache storage memory of your phone has been exhausted, it may also not detect your fingerprint. To fix this issue, find out what is taking up all the space in your storage and delete them. In addition, you can select the ‘Clear cache’ button and delete cached items. This will free up space and make it possible for you to use the fingerprint option.
Part 3. Using TECNO-Approved products
There is no assurance that 3rd party products will be compatible with your TECNO device. When it comes to using the fingerprint function, this is particularly important as the functionality of the fingerprint sensor may be affected by the thickness of the screen protector, and sometimes the protective case may interfere with the sensor’s operation if it touches it.
Thus, you should only use TECNO - approved screen protectors and protective cases for your devices
Part 4. Hard reset your device
As a last option when all else fails, you can hard reset your phone.
- How to hard reset your Tecno phone
- Press and hold thepower button together with the volume up button until your display changes to ‘TECNO’
- Repeat immediately until the screen shows ‘No command’
- Hold power button for 2 to 3 seconds and press the volume up button alongside to enter the stock recovery option.
- Using the volume up and down buttons, navigate the stock recovery function.
- Select the ‘wipe data and factory reset’ option by pressing the power button
- Scroll again to choose YES
Once done, the next thing is to wait until the process is complete after which you will need to reboot the system. Your device will have been successfully restored to default settings.
Note: Reset the device will delete all the data on your phone so please backup the data in advance before you reset it. You can also learn here simple steps on how to hard reset your Infinix phone.
