Hello, been using this rom for a few days now, its working great! I've only had one issue so far which I wanted to report, partial screenshots don't work to the edge of the screen. As soon as you get within a cm of the screen edge the partial screenshot gets interrupted? Like it doesn't move past that point but it also doesn't confirm or clear the screenshot selection.

I am having an issue with the fingerprint unlock.
It works directly after reboot but after some minutes to a couple of hours it stops working.
I cannot unlock the phone, use biometric unlock in apps as well as add a new fingerprints.
The fingerprint area light up, but quite dimly.
Does anyone have any suggestions?

    When the smartphone is in Standby mode, the fingerprint reader area is still active. One can unlock the phone with it without pushing the power button first.
    This is a feature.

    This turns on the phone in my pocket all the time leading to annoying vibrations.
    Please put the phone in your pocket with screen facing outward so that it doesn't hit your chest.

    @kyasu great ROM but the fingerprint doesn't work for me and it has a weird pattern every time i try to register a fingerprint.
    This is how the flow goes always:
    1. first 4 prints registered
    2. next 6 prints are not registered (doesn't throw an error, it just doesn't move the progress status line)
    3. next 5 are registered
    4. next 5 are not
    5. the next one completes the whole process, without getting into the part that it asks me to add fingerprints from the thumb sides.
    i'm on the right kernel, clean install etc.
    Any thoughts?
    I don't have such issue.

    @kyasu This is really an awesome ROM. Thank you so much! I'm testing it now for several months and hardly find any bugs/instabilities. You're great for making this!

    There is only one thing I noticed recently where I'm not sure if it's a bug or a feature (cannot find an option to turn it off):

    LineageOS is a free, community built, aftermarket firmware distribution of Android 12, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    This is an unofficial LineageOS 19 build for the global version of Xiaomi Mi 9 SE (grus).

    Requirements
    • Required firmware version is MIUI V12.5.1.0.RFBMIXM.
    • Required TWRP is provided in this post (see below) that returns the correct 'ro.product.device'.
    • Formatting data (all user data is wiped, including internal storage) is a must if MIUI was previously installed.
    • Twrp can't decrypt data in android 12, so you need to install updates via adb sideload.
    Known Issues
    • Please tell me
    Instructions
    1. Flash TWRP recovery via fastboot
    2. Boot to TWRP recovery (Vol UP + Power)
    3. Format Data (backup sdcard before format) if MIUI was previously installed
    4. Flash ROM (lineage-*.zip) via adb sideload (Advanced -> ADB sideload)
    5. Flash Gapps (MindTheGapps-12.1.0-arm64 is recommended) via adb sideload
    6. Reboot
    Enjoy!

    NOTES
    • Safetynet can pass on this ROM (without magisk).
    • Regardless of the actual security update date, android security update is always displayed as 2021-04-01 for safetynet passing.
    • Recommended camera app is GCam Port: BSG 8.1 that can handle all of three lenses.
