Hello! I'm sorry to hear that your Tecno Pova 2's fingerprint scanner is not working after the last update. Here are a few suggestions that you can try to resolve this issue:
1. Reboot your device: Sometimes, a simple reboot can fix minor software glitches. So, try turning off your phone and turning it back on again to see if it resolves the problem.
2. Clear cache: Clearing the cache of the fingerprint scanner app might help. Go to Settings > Apps > Fingerprint Scanner > Storage, and then tap on "Clear cache." Restart your phone and check if the fingerprint scanner works.
3. Delete and set up fingerprints again: Remove your existing fingerprints from the system and set them up again. Go to Settings > Security & privacy > Fingerprint > Fingerprint Management. Delete all the existing fingerprints and then add them again one by one. Make sure your fingers are clean and dry when scanning.
4. Update your phone's software: Check if there are any new updates available for your Tecno Pova 2. Software updates often include bug fixes that can resolve issues with the fingerprint scanner. Go to Settings > About phone > System updates and check for any available updates.
5. Factory reset: If none of the above steps work, you can try performing a factory reset. However, please note that this will erase all data on your phone, so make sure to back up your important files before proceeding. Go to Settings > System > Reset > Factory data reset.
If none of these solutions work, it could be a hardware issue with the fingerprint scanner. In that case, it would be best to contact Tecno's customer support or visit a service center to get it repaired or replaced.
