Hi! I'm sorry to hear that you're having issues with your Tecno Pova 3's fingerprint lock after performing a software update. Here are a few things you can try to resolve the issue:
1. Clear the cache of the fingerprint application: Go to Settings > Apps > Fingerprint > Storage > Clear Cache. Restart your phone and check if the fingerprint lock is working.
2. Remove and re-add the fingerprint: Go to Settings > Security > Fingerprint > Fingerprint Management > Delete. Then, follow the steps to add your fingerprint again.
3. Check for software updates: Make sure your phone is running the latest software version. Go to Settings > About Phone > System Update > Check for Updates.
4. Perform a factory reset: This should be a last resort, but if all else fails, you may need to perform a factory reset. Note that this will erase all data on your phone, so make sure to back up your important files before doing this. Go to Settings > System > Backup and Reset > Factory Data Reset.
If none of these steps work, it may be a hardware issue and you should contact Tecno customer support or bring your phone to an authorized service center for repair.
Same problem with me. Lahat na ng possible steps na nakalap ko online ginawa ko na. Wala padin, updated nadin sa latest. Wala padin. Ang hassle kasi na walang fingerprint. Nakakainis tong unit na to. Badtrip.
