Wie deaktiviere ich den Fingerabdrucksensor unter dem Redmi12 C?

 

[cartridge_case]

Einfach alle gespeicherten Fingerabdrücke löschen?! Oder was meinst du?

Komplett auch im System die möglichkeit ihn zu aktivieren deaktivieren

Das geht unter MIUI ohne root nicht.

On Linux (and Android) it is possible to disconnect a device from its driver[1]. The fingerprint driver (denoted as fpc) on my LG G5 has the name fpc1020. Searching in the /sys path gave me the folder /sys/bus/spi/drivers/fpc1020/. This folder has four files: bind, unbind, uevent AND spi8.1. What we do is to unbind the device spi8.1 from the driver fpc1020.

Now how to disable the sensor:

we need to find the driver name:
Try this command: find /sys/bus -name 'fpc*'
For me it's: /sys/bus/spi/drivers/fpc1020/

we need to find the device name:
The device name is the fourth file in this folder.
ls /sys/bus/spi/drivers/fpc1020/ (depends on your result from 1.)
For me it's: spi8.1

unbind this device:
echo spi8.1 > /sys/bus/spi/drivers/fpc1020/unbind (depends on your result from 1. & 2.)
Now you are not able to use the fingerprint sensor until the next restart.

Grob analog dazu bei deinem Gerät.
