Device

Poco x6 (garnet)

crDroid version

crDroid 12

Exact version / Build date

12.9 28.04.2026

Bug description

The in-display fingerprint sensor is inactive during Always On Display (AOD). A padlock icon is shown instead of the fingerprint indicator. The sensor only initializes and becomes functional after the device is woken up via the physical power button

Steps to reproduce

Enable Always On Display and verify that fingerprint unlock works normally on the lock screen.

Lock the device and let it enter AOD mode.

Observe the UI: A padlock icon is visible at the bottom, and the fingerprint sensor does not react to touch.

Press the Power Button to wake the screen.

Observe the UI again: The padlock icon changes to the fingerprint icon, and biometric unlocking starts working immediately.

Relevant log (logcat/build log)

No response

Solution

The fingerprint sensor does not respond (no optical light-up or haptic feedback) while AOD is active. It only becomes functional after the display is fully woken up by the power button.
Expected Behavior:
The sensor should remain active or wake up upon touch during AOD, allowing for seamless biometric unlocking without physical button interaction.

I checked here and it doesn't seem to be a bug in the source code.

This change in AOD was to correct the UDFPS screen flash during sleep transition.

This was the commit of the change.

What do you need to change in the village, to stay, to make this a commitment?

I can confirm that it stopped working on Oneplus 13 (dodge) on the 04.05.26 update
