Mi MIX 2S

[Other] Issue with fingerprint sensor

Hello,

I own a Mi MIX 2S and had issues with the fingerprint sensor. At the beginning it failed only sporadically but after some weeks it did not work anymore.
The CIT displayed the following result:
  • SPI test: failed
  • Reset pin test: failed
  • Interrupt pin test: failed
  • Pixel open test: spinner


So I decided to replace the sensor. After replacement it stillt does not work. All test (except pixel open test) succeed, but an alert is displayed in chinese, which I can't understand.


Can anyone help me?

Thanks and regards
Chris

Thanks for your answer. I already did a factory reset, unfortunately it did not help.

The text in the screenshot said: "sensor has either failed testing or hasn't been tested"

I am looking for a solution for the last 2 months.

I changed 2 new sensors, nothing did help.

Now I've realized, that the problem seems to rely on MiUi-Software.

Factory reset and installing MiUI 12.0.2 stable Xiaomi.eu didn't help.

Anyone tried any other Custom ROM? I like MiUi, but if there will be no support any longer...
