Are you using any screen protector or changed screen? If so then it can be the root of the issue.
If not try this: go to Settings > Display > Colors > and set the color mode to Natural, then try again.
If the problem persists, try using another finger.
Here fod is working fine, I've registered many times the finger at first attempt

你好。是的，我已经提出了成为官方的请求。希望我能被接受。

Can PixelOS recovery handle encypted data partition?

 

[balgxmr]

Can PixelOS recovery handle encypted data partition?

As long as you don't flash DFE then yes, it keeps encrypted and it's capable to do OTA updates (I enabled them but haven't tested yet). You can still use adb sideload or otg to flash manually ^^

I seem to have lost fingerprint after the new update
Edit : Nevermind wrong file flashed sorry

Hey, thanks for the update and ROM! Just flashing it rn, question tho - since you mentioned dropping vulkan and ProtonAOSP which pixelOS is based on uses it for major gains in performance - do you mean dropping it completely or reverting to prev version?

Hi! Glad to hear! Welcome . And yeah I'm dropping Vulkan as renderer, i know that it's better since it boosts performance, but, at least on Mi 9, it's just not the perfect renderer. It causes weird artifacts/color issues on videos and also makes some GCams like LMC to crash. So I dropped it, more stable and the change isn't noticeable. ^^

I saw in some other Xiaomi devices that MIUI camera is included in PixelOs. Is this built the same case?

 

[psycho87]

I can't see unlock OEM in developer options ?

It is not included, because ANX cam for cepheus doesn't work properly on A12/A12L (Vlog/Portrait modes crashes, for example.) so i didn't included it
