I replaced the power button on my Poco F3 with an original one that I bought from someone selling spare parts from broken phones. Now, the fingerprint option is missing from the Settings, and when I go into the Hardware Test Menu (CIT) to test the Fingerprint sensor, it says "Unknown Fod sensor type. Test failed!"

There is no app for the Fingerprint sensor in Manage Apps under All apps, so I cannot use the "Clear data and cache" option.

I don't know if it matters, but I did have the fingerprint set up with the original sensor, so maybe that's why it's not working now with this one. Will a Factory reset maybe help, or is there some other option. Is the sensor that I bought bad, and I need to buy a new one?

What does a number on the power/sensor cable mean? Do I need to find a power button/cable with the same number as original, or does that not matter?
