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:
# ***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.
# ***Clear cache and data of the fingerprint app***: Go to Settings > Apps > Fingerprint > Storage > Clear Cache and Clear Data.
# ***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.
