Why Does Mobile Phone Fingerprint Stop Working After System Update?

System updates are essential for mobile phones as they bring new features, bug fixes, and security enhancements. However, it is not uncommon for users to experience issues with their fingerprint scanners after a system update. This can be frustrating and leave users wondering why this happens.

One of the main reasons why a mobile phone fingerprint stops working after a system update is compatibility issues. The update may introduce changes to the operating system or security protocols that are not fully compatible with the existing fingerprint scanner technology. As a result, the phone may fail to recognize or authenticate fingerprints properly.

Another possible reason is that the system update could have caused software glitches or conflicts within the device's firmware. These glitches can disrupt the communication between the fingerprint sensor and the operating system, leading to malfunctioning or non-responsive fingerprint recognition.

Additionally, manufacturers often release firmware updates specifically designed to improve fingerprint scanning performance. If these updates are not installed alongside the system update, it can lead to compatibility issues and cause the fingerprint scanner to stop working.

It is also worth noting that hardware-related factors can contribute to this problem. Over time, dust particles or dirt accumulation on the sensor surface can hinder its ability to accurately read fingerprints. A system update might trigger a recalibration process that requires a clean sensor surface for optimal functionality.

To resolve this issue, users can try several troubleshooting steps such as restarting their device, cleaning the fingerprint sensor area gently with a soft cloth, re-registering their fingerprints in case of data corruption during an update, or even contacting customer support for further assistance.

CLEANING THE FINGER PRINT SENSOR

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.

FIXING DAMAGED FINGER PRINT 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 phone before you go to service centers.

FIXING SOFTWARE ERROR

Most mobile 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 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.

HOW TO ADD A DELETE FINGER PRINT?

Depending on your particular requirement, you may need to add new prints or delete old ones. Here is how to do just that

1.      From The Main Menu, navigate to the Settings icon and select it.

2.      Scroll to security options and click on it.

3.      Find the Fingerprint management function under the security tab and open it

4.      Click add to create a database of new fingerprints. Ensure you save the fingerprints from multiple finger

5.      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

6.      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.

In conclusion, while it can be frustrating when your mobile phone's fingerprint scanner stops working after a system update, there are various reasons behind this issue. Compatibility issues between updated software and existing hardware technology along with software glitches or conflicts within firmware could be responsible for this inconvenience. By following some troubleshooting steps and seeking assistance if needed, users can often restore the functionality of their fingerprint scanner.
