Fix Fingerprint not working, not responding and all other bugs and issues with the sensor on your Xiaomi Redmi & Mi phones with the complete detailed methods. Try the solutions below to solve the problems with the fingerprint scanner on Redmi and Mi

Fix Xiaomi Mi & Redmi Fingerprint issues with the best solutions below. Fingerprint Scanner or Sensor is the newest and heavily used feature on almost all the new smartphones. The Fingerprint acts as a tough layer of security for the device as it uses the biometrics of the finger to detect the original users of the phone. Sensor errors are common on Android phones and let us read them in detail.

Today in this post I will tell you the best solutions to fix all the Fingerprint issues on all the Xiaomi devices. As the Fingerprint issues are mostly due to software glitches, therefore, solutions to fix the fingerprint problem are generally the same for all the Xiaomi Models. That is all the solutions below that can work for all Xiaomi devices.

You can try the following methods on Xiaomi phones like Redmi Note 5, Mi A1, Redmi 5 Plus, Redmi Note 4, Note 5 Plus, Redmi 5, Xiaomi Mi6, Mi Max 2, Y1, Mi Max 3, Note 5A, Mi 6 Plus, Redmi 3S Prime, Poco X1, Poco X2, 4 Prime, Mi 6C, Redmi 3A, Mi 5S Poco F1, etc. Fix the issues like Fingerprint Not Working, Not responding, an error occurred with Fingerprint Scanner, couldn’t add fingerprint try again, etc.

Fix all the Xiaomi Redmi & Mi Fingerprint Issues

Note: I believe that you have rebooted the device but the problem is not solved. If not yet, then first restart the phone and check for the fix. If not done with a simple reboot then proceed with the solutions below.

Again Register Fingerprint

If your device fails to recognize your fingerprint, then you should try re-adding your fingerprint. With time the fingerprint sensor may not be able to recognize your fingers due to wear and tear of biometrics of your finger and it is pretty normal. Besides, there are times where if you do not properly set the fingerprint, it can cause such fingerprint issues.

The best solution is to register your fingers again. First of all, delete all the previously stored fingerprints.

First, you need to head on to Settings > Lockscreen & Password > Manage Fingerprint.

 

Remove_Fingerprint

  • Head on to Settings > Lockscreen & Password

Lockscreen_and_Password

  • Click on the Screen Lock & Fingerprint option.

Screen_Lock___Fingerprint

  • You can Add a Fingerprint.

Add_Fingerprint

  • Once it is completed, you will get a confirmation of Fingerprint added.

Free Up Internal Storage

Don’t know how they are linked but many smartphone users from multiple brands have reported that a fully filled internal storage is causing the fingerprint to not function properly. I recommend you to please clean up the internal storage. You need to keep at least a few GB of storage for apps data to be properly stored without causing any complications.

Clear Cache of the Phone

System cache is a small data stored by the Android system that helps phones load apps and other functions quickly. Heavy cache build-up may cause the fingerprint to not respond quickly. Just clear the cache of your mobile, this will clear the cache and does no harm to your files. The below steps may vary for MIUI Versions.

Step 1. Open the Updater app.

Step 2. Tap the Menu button > Reboot to Recovery mode. Tap Reboot now.

Step 3. In the Recovery mode, you can use the Volume buttons to move the highlight, and the Power button to select. Here, select English.

Step 4. Select Wipe & Reset and select Wipe Cache.

Delete Mi Cache recovery ModeStep 5. Tap Yes for confirmation.

Step 6. When the process completes, tap Back.

Step 7. Select Reboot and Reboot to System.

Try a Simple Fix

This simple fix can solve the issue in many of the devices.

Go to Developer options → Disable “Don’t keep activities”. Check for the fix.

If you wish you can also make Memory optimization (High). Reboot the phone and follow regular fingerprint adding procedures.

For Developer option

  • First, go to settings- about the phone
  • Tap 5 times in the MIUI version after
  • You will get the developer option in additional settings.

Switch to Guest User

  • Pull down the notification bar and here tap on the user account (right-top). Switch to the Guest user, you can also find the option under Android Settings.
  • Try to add the fingerprint.
  • If the solution works, switch back to your normal user account and clear the internal storage and add a new fingerprint. Done!

Reset the Phone

If nothing works, hard resetting the device is the only last resort. Some files may corrupt the fingerprint functioning and it may not be possible to fix it with any simple tweaks. The best option is to reset the device. This will clear any obsolete files clear the device to normal.

Try a Workaround

Workaround I

Just change the Pattern to Pin and add the fingerprint. When asked to press Next on-screen, Do Not Press Next! Put your finger on the scanner instead, and it will progress to the next page and follow the instruction until complete. The fingerprint should work fine.

Workaround II

Go to Settings → Screen lock and then Register unrecognized finger. Now don’t delete the fingerprints but remove the screen lock itself and then add screen lock and register your fingerprint.

Fingerprint Authentication

Solution 5. Reset the Phone

If none of the above works then resort to resetting the device. I recommend you to reset the device from the recovery mode.

Step 1. Open the Updater app.

Step 2. Tap the Menu button > Reboot to Recovery mode. Tap Reboot now.

Step 3. In the Recovery mode, you can use the Volume buttons to move the highlight, and the Power button to select. Here, select English.

Step 4. Select Wipe & Reset and select Wipe All Data.

For Rooted Devices/Flashed ROMs

Delete Some Files

Open the File Manager and go to data/system/

Here delete two files with extension ‘.key‘ and three files with word ‘locksettings‘in their full name.

Reboot the device and now again add a fingerprint. Done Cheers! 

You can also Delete

Delete these files on your rooted Xiaomi Phone.

/data/system/users/0/fpdata/user.db
/data/system/users/0/settings_fingerprint.xml

This could partially fix the issue.

    Hi,

    A while ago I changed my battery in my my RN4 and we’ll I assume I got a defective battery because the Temperature doesn’t cross 25 degrees.
    A few days later my fingerprint stopped detecting, I deleted and tried to add back new fp but no luck, kept failing.
    I went ahead and bought a new sensor,just installed and same issue.
    Also tried dev rom and stable and epic rom same issue. I did a hardware test and it says pass.
    Self test :Pass
    Checkboard test(number of dead pixels – 0

    Hi
    Thanks a TON . I was stuggling unable to add fingerprint. Your Solution 2 & 4 worked for me. Now I could add the fingerprint

  13. george says:

    my finger print doesn’t give any sign of sensor is it problem in the phone or the system. i couldn’t add any fringe print password.

  14. Maurice Fortin says:

    I WISH could totally turn this off 100% so that finger does NOT wake up screen at all, it is SO ANNOYING, I had seen plenty of people make this recommendation and Xiaomi never “responded” saying would add this “simple” feature…it should be a simple “toggle” to activate the feature or toggle to have it OFF for people who “do not” want it (so annoying as I have had phone “wake up” with nothing touching the sensor, and yet touch sensor again does not put back to sleep go figure).

    all the suggestions for disable it have no effect, just “take back of phone apart, take out the wire for the sensor, problem solved” or “put a layer or 2 of tape over the sensor”
    blekk and double blekk.

    figure it would be “easy enough” to add ability to “toggle off completely” as if you root the phone you can completely remove the code allowing the sensor to work, but if you “screw up” you just bricked your phone. a few lines of code would allow a “toggle”

  19. Alexandre Nobrega says:

    My name is Alexandre and I’m from Brazil. Yesterday, creating a second space in the Xiaomi Redmi 5 Plus, I inadvertently disabled my fingerprint and could not enable it at all! I just asked for my PIN and said that it was not possible to register my fingerprint. I was already desperate when I found your site. Boy, God bless you! I had tried to clear the cache first (which I read on another site), but it did not work. With your solution number 2 worked! I have no words to thank you. Such a simple thing. Thank you so much again.

    Hi,
    I have Red Mi Note 4 ,
    I have set App lock by using my finger print scan on system settings & also on some applications.
    But now when I try to open settings, it says can not read finger print & asking for pincode of pattern lock, while I have never set any pattern to lock my mobile.
