The fingerprint on the Xiaomi Redmi 8 is a convenient way to unlock, but sometimes it starts to malfunction: it does not recognize the finger the first time, requires several attempts or completely stops responding. Other times, users want to temporarily turn off the scanner for security reasons β for example, if children use the phone or there is a risk of unauthorized access through forced finger-stroke. In this article, we will discuss all possible ways to remove fingerprints, including standard MIUI settings, forced reset via Fastboot, as well as the nuances of working with different versions of the firmware.
It is important to understand that the process is different from removing a pattern lock or PIN-The fingerprint scanner on Redmi 8 is tied to the hardware module, and it doesnβt always go smoothly β especially if informal firmware has been installed or root rights experiments have been conducted before. We will also consider what to do if the system does not allow the fingerprint to be deleted due to errors such as βFailure to delete dataβ or βScanner does not respond".
Why you might not be able to turn off your fingerprint
Before proceeding to the instructions, it is worth understanding the possible reasons that prevent standard removal:
- π Scanner malfunction: physical damage to the sensor (for example, after a phone crash) or software glitch, due to which the system does not see the module.
- π Active binding to MI-Account: on some versions MIUI Deletion of biometric data is blocked if the phone is linked to a Xiaomi account with the βFind Deviceβ function enabled".
- π± Unofficial firmware: custom builds (such as LineageOS or Pixel Experience) may not work properly with Xiaomi hardware modules.
- π§ Root rights or system modifications: changes in files /system or /vendor Sometimes biometric sensors are broken.
If your Redmi 8 falls under at least one of these points, standard uninstallation through settings may not work, which will require alternative methods, which we will discuss below.

Method 2: Remove through the Engineering Menu (for power users)
If the standard method didnβt work, you can try resetting the scanner through the Engineering Mode, which is suitable for devices with root rights or unlocked bootloader, but requires caution β incorrect actions can lead to a system failure.
Instructions:
- Open the Phone app and type the combination: ##6484## (some firmware may run ##64663##).
- You will be taken to the MTK Engineer Mode menu (if the combination doesn't work, try ##4636## and find the Hardware Testing tab).
- Go to Fingerprint Test or Biometric Test.
- Press Clear FP Data (or similar reset button).
- Confirm the action and restart the phone.
β οΈ Note: On some versions MIUI If nothing happens after you enter the code, your firmware doesn't support this method. Don't try to log into Engineer Mode through third-party apps, this can lead to blocking. IMEI.

Method 3: Fastboot reset (if the scanner is not removed)

|---|---|---|---|
| Standard settings | β No. | β No. | β Very simple. |
| Engineering menu | β No. | β No. | ββ Middle-Average |
| Fastboot | β Yes. | β Total reset | βββ Hardly. |
| Hard Reset | β No. | β Total reset | ββ Middle-Average |
If the scanner stopped working after the firmware was installed via Fastboot, it means that the module was damaged at the hardware level, in which case only replacing the sensor in the service center will help.
Method 4: Hard Reset (Hard Reset)
If no methods work, the last option is a complete reset, which will delete all data from the phone, including fingerprints, accounts and installed apps, and make sure to back up important files before the procedure.
