My Xiaomi's fingerprint sensor became slow and unresponsive after a few months, what solutions will help solve the problem?

According to the users' reviews and experiences, we can offer these tips:

Remove your fingerprints from the list of registered ones and add them again in the settings.

Make sure the software on your phone is up to date. Xiaomi often sends out updates that fix these kinds of issues.

Check your MIUI battery optimization settings. If you turn off optimization for the fingerprint reader, it will work faster.

If none of these work, you may need to do a factory restart, but first try the other steps.

If there is any other method you have applied, please feel free to share. You may also file a complaint on our website.
