My tecno spark9T can't support fingerprint lock

Hi, @aynalemworku. Lore here.

I’m sorry to hear that. If you’re having issues with your fingerprint scanner, you can try deleting the saved fingerprints and re-registering them. If the issue persists, you can try the following steps:

1. Check for software updates: Ensure that your Tecno Spark 9T is running the latest firmware version. You can check for updates by going to Settings > System > System Software > System Software Update and Settings > Update System Software.
2. Clear cache and data of the fingerprint app: Go to Settings > Apps > Fingerprint > Storage > Clear Cache and Clear Data.
3. Restart your phone: Restart your phone and try using the fingerprint scanner again.

If none of these steps work, you may need to contact Tecno support for further assistance.
