Ask anyone what’s the quickest way to unlock a phone and the answer will be by using the fingerprint sensor. It literally takes a second to unlock the phone and you can start using it as you want. The scanner adds a pretty sophisticated layer of security since your passwords can be guessed by fingerprints and are less likely to be forged. What if you found that the fingerprint sensor is not working on your Redmi K50 Gaming?
Turns out there are many instances where users have reported similar issues. It could be for a second or the sensor could be down for a long time. Here are some troubleshooting methods you can use.
1: Check if your Fingers are clean [ Fingerprint sensor not working on Redmi K50 Gaming ]
A fingerprint sensor is a sophisticated tool that scans fingerprints and allows access after authentication. Damped or dry or dirty fingers can discourage a fingerprint sensor from registering the stimuli and since the sensor was unable to authenticate your fingerprint, it won’t work even if you are the phone owner and use the right finger the right way.
Use a napkin or a tissue to wipe clean your finger and try again. We usually recommend registering two or three fingers so in case if your index finger is dirty, you can still use the middle finger or thumb to unlock your Redmi K50 Gaming.
2: Check if the Fingerprint sensor is clean
Assuming that your finger is clean, now it’s time to look after the fingerprint sensor. If it isn’t clean, it will have issues authenticating the user. Oils, liquid, or any other stuff covering the fingerprint sensor partially or fully will distort its ability to register a touch, and thus, you will face difficulty unlocking your Redmi K50 Gaming this way.
You can use a slightly wet cloth or tissue to clean the module. It goes without saying, you shouldn’t use hard or sharp objects like keys to remove debris collected on the module because it will cause more damage.
3: Reboot the phone [ Fingerprint sensor not working on Redmi K50 Gaming ]
If you thought this method might not work here, think again. Turns out temporary software glitches can cause the phone’s fingerprint scanner to behave abnormally such as it won’t register a fingerprint. Thus, a quick reboot and you are actually on your way towards fixing this temporary software glitch.
4: Software Updates
Outdated software should be updated from time to time to relieve your Redmi K50 Gaming from any bugs. If you are complaining about the fingerprint scanner not working issue, it could be because of outdated firmware.
It won’t take much time to check if there’s an update available. If yes, simply download and install it via Settings >> About Phone >> Software Updates (System Updates) and this should do the trick.
