[Q&A] My phone don't recognize my fingerprint sensor anymore

Changing the app I was using, I clicked on screen pinning accidentally. I was using the infinite screen and tried to unpin the screen of too much ways, but I couldn't. So I rebooted my phone to get it back. But, when he started, the system don't recognized the fingerprint sensor anymore. Simply I didn't had the unlock for fingerprint option anymore. I tried to wipe (almost) everything, but didn't work. I tried to install other rom, and tried to install a gsi, but all that roms and gsis simply don't recognize that phone has an fingerprint sensor. I think that the problem was with the screen pinning and that created an bug on system. What I do?
I installed an app that test the fingerprint sensor, but he showed an error that said "this app only works on phones with fingerprint sensor.
I was using MIUI V10.2.2.0 stable when it happened :(

so when you tap your finger on sensor it tells you try again or just nothing happens?

The fingerprint unlock option simply disappared. It's like I'm with a cell phone without a sensor.

Hmmm, since that option completely disappeared, I say it's hardware fault.
Since you already tested other roms from what I understand, can only be that... Hardware fault

I think when I rebooted on the screen pinning, something bugged the sensor. When the phone booted, I had no longer the option to unlock by fingerprint in the settings...

It might be.  But, it was very coincidental that this happened exactly when I had this bug with the screen pinning

oh now I get it. your device system now thinks that redmi S2 do not have that feature . it is big hardware problem but it could be fixed. Go to settings-installed apps. And search fingerprint. Result will be two files. if you did not found that files then it is really gone.
