Hello,
i have had problems with my "InDisplay" fingerprint sensor for a few months. In the beginning he didn't recognize my finger anymore. The backlight light comes on, but I should press harder. After several reboots it worked again. But then at some point this trick no longer worked. But after a security patch or the last update to MIUI 12, the sensor works for 2 days without any problems. Then again not. The CIT test recognizes the sensor, but only values between 0 and 1 are output. I did the test right after the MIUI12 update. Then I got values over 200. I haven't reset the phone yet. That would be my last step. If the Sensor not working, i can not train my finger. Anyone have an idea?

Phone MI 8 Pro
MiUI Global 12.0.1 Stabil QECMIXM Android 10QKQ1.190828.002
