Face Unlock

[joseehilton]

Hello.

Its possible to add a feature who let us swipe to unlock the screen, because isn't a good thing when u want too see hours or want to change music it unlock instantaneous, there's a option but i think that don't work or isn't a feature that do this, you guys can do that or only xiaomi team?

Nothing we can do here, sadly.

Potentially it's possible with rooted phone. I've modded my Redmi 5 Plus to map the fingerprint sensor to power button. As a side effect I can switch on power by touching FP sensor with *any* finger. An unregistered finger wakes up lock screen but doesn't unlock. A registered finger unlocks.

All I had to do is to copy /system/usr/keylayout/uinput-fpc.kl and /system/usr/keylayout/uinput-goodix.kl to /sdcard/ and change a line in boths files:

key 353 DPAD_CENTER

changed to

key 353 POWER

Then I installed Magisk module "Custom Keylayout" and reboot. Now FP sensor has an additionaly function as second power button and I can switch on lock screen with my little fingers. FP sensor works furthermore as before.

Other mods are also possible, eg: https://www.xda-developers.com/enable-fingerprint-selfie-xiaomi-redmi-3s/

Completely irrelevant to the discussion, the OP talks about Face unlock, not fingerprint unlock.

So on an unmodified software, phone shouldn't wake up by touching fingerprint sensor with any finger? Did I understand correctly? because my Max 3 wakes up when I touch fingerprint sensor without any fingerprint added (which is little annoying and I don't see any option to disable this).

Yes, that's true. This behavoir comes with stock global ROMs from Xiaomi and with ROMs from here.

Also I wonder why there are two active input devices running for FP sensor: "uinput-goodix" and "uinput-fpc" (see /proc/bus/input/devices)

No idea whether it's a bug or a feature. I use it as a feature to wake built-in lockscreen controls of PowerAmp music player. That works fine with Xiaomi's lockscreen without unlocking device.

It's here since Friday, isn't it?

Yes, for most 8.1/9.0 devices (except MIMix2S).
The feature should be available for all devices in the upcoming public release.
