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?

It's crashing again, only on back Camera.
No such an issue with MGC_8.1.101_A9_GVr_snap.apk. Just sometimes it starts with black screen (no image) but it resumes, maybe closing an reopening it .
I instead noticed that, both in gcam and open camera, the electronic level reports wrong direction. Any clue?

Can you send me the link to download? I found MGC_8.1.101_A9_GV1zfix_snap.apk which don't have HDR option.

Hi guys

besides the fact that the fingerprint sensor does not work satisfactorily for me, I have now noticed another "problem":

When I make outgoing calls, I do not hear any call ringing.
Is this problem known or are there any possible solutions? I have also tried to use another "phone" app, same result.

Thanks and greetings

Hello, would there be anyone kind enough, to give me little more detailed steps on how to install and then update the clean ROM, independent on what was previously installed? Since I've already done it, but sometimes there were problems and I am scared, that I will **** something up.
When I want to install the ROM I have to.

1. Flash custom TWRP using fastboot.
2. Wipe all data.
3. Flash the ROM with sideload.
4. Flash MindTheGapps with sideload.

Is that correct? I think there's something to do with the firmware, but I am not sure.

Yes, that ist correct.


There's something else I just experienced, but only twice so far.
After a few days of use at some point the screen color saturation suddenly goes down and everything looks pale. A reboot fixes that but I haven't found out what causes it. I suspect it has to do with the livedisplay mode for direct sunlight but I can't confirm that yet.

Hello, Can someone confirm if internet sharing works? Since the last update I've noticed that it won't let me activate it.
I don't know if it will be a dirty flash failure or a firmware bug. Thank you.

I've noticed that the display did not switch back to sdr mode after watching hdr video.

    Hello, is it possible to dirty flash the new update without any issue?
    Yes. I have updated mine with the last version with adb sideload over the previous one. First adb sideload the firmware and when It finish, adb sideload the last version of mindgapss. Reboot and everything shoud be fine. I had no problem.

    Fantastic build. Used this to replace the LOS17 build previously shared over Telegram. The fact that this can pass security tests means a lot less hastle with banking apps. Generally, no problems with this build at the OS level. It is very stable unlike the very old build from the Telegram group I was using before the team dropped it in favour of KowalskiOS.

    One thing that came as a surprise is that the recorder app records in full stereo whereas the old build was in mono and third party apps were problematic. This is fantastic as my Xiaomi phone have largely made my fieldwork devices redundant as the quality is better than all but high-end recording devices (which will not fit in a pocket!). Basically, the smaller varieties of Mi phone for me are for camera, power

    I'm not mad on the Android12.0 graphical changes, but that is not of importance. GCam is working fine for the most part. Some apps have problems such as the in work app from Microsoft but can live without that...

    The install was without issues, following instructions on #1 and the further details later on #63. Will report any problems as I find them.

    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.
