<![CDATA[POCO X3 NFC: FingerPrint reader always on :(]]>Hi there,
I have a freshly flashed device POCO X3 NFC. It seems to be working just fine, except one thing:

The fingerprint reader, which is also a power button, stays always on. Meaning it reacts on every touch of the skin. Even if there are no finger prints registered and the device is not set to use FP to unlock the screen.

It is getting super annoying, because the button emits certain "behaviours" under different circumstances: Mostly it acts as "enter" (new line) when typing messages in various applications; in app switch view it selects/switches to the first app etc.

Can I please ask for help, if this FP reader can be disabled? (so that the button really works as just an ordinary power button).

Thanks a lot 🙂

The device came with Android 11, I downgraded to Android 10 using the image:
surya_global_images_V12.0.9.0.QJGMIXM_20210508.0000.00_10.0_global
...and using the attached script 'flash_all.sh'.

I'm thinking if there is a way to re-image it back to Android now? To check, if the button worked ok? (I never re-imaged UBports phone back to Android before, so not sure about the implications...)

On android, the FP / power button was working fine?
Also, did you install the correct stock ROM before flashing to ubuntu touch?

You're using the 16.04 stable channel?
I have the same phone and i don't have this issue.
