Thanks for the tip! I had V9 of that version 8.6 installed and it still crashed when switching to 2x or 0.6x lenses in video mode. With V10 it doesn't crash anymore althoug it still seems a bit buggy. But I will keep ok testing that!
I tried snap because some older version kept crashing unless always clearing cache, so on snap does it work with HDR off for you? HDR ON takes from several seconds up to 10 seconds processing, HDR off doesn't save the picture at all.

Though is it Android 13 thing that in launcher app menu where it says on top "Search apps" and it has different profiles (personal,work) below, the padding/vertical space has disappeared between this "Search apps" and profile buttons? Did flash over 19.1

With HDR turned off the app crashes for me. I disabled energy saving for the gcam app so it can process the images in background while I'm going back to the app where I need the picture. Processing time varies from 2 to 10 seconds or something.

Also after further investigation it appreas that movies only work with 0.6 and 1x lenses. When selecting 2x the screen stays black and you have to force quit the app in order to work again.

And still no support for 60fps. Althogh you could record in slomo and speed it up to normal speed.

Yesterday did the update from @kyasu's Lineage 19.1 build to Lineage 20. The ROM is very stable and fluid, and all seems to work perfect, except there are some problems with my Bluetooth headset. My Redmi Buds 3 are very buggy while streaming on HD audio codec (AAC). The sound is very laggy, glitchy and unstable. The only solution to use my Bluetooth headset for now is to switch it from AAC to SBC codec. AAC HD audio worked very well on lineage 19.1 build. How can I help with investigating this? Should I grab some logs while I'm on AAC codec?

When I disable the HDR+ option, the camera don´t save the photo. It happens with the three lenses and with the MGC v12 too. Can you try it? thank you
Can confirm that, at least it doesn't crash anymore.

Also I noticed the SloMo videos aren't available. You can enable them in the developer options but they make the app crash.
It's not a function I need everyday so I don't really mind for now.

@kyasu I'm encountering an issue where both stock camera app and Gcam won't recognize the main camera lens. I will post a screenshot below and as you can see it only detects x0.6 and x2.1
It's annoying because I have to move much farther to take a photo.
What could possibly cause this issue? It has always worked normally, maybe the hardware got ****ed up?

Installed this over unofficial LOS19 August build, also from kyasu, and all working fine. Dirty flash, clearing only cache & dalvik. So far all good after a few days for all the main apps.

With my grus, both stock camera and Gcam recognize the three camera lenses. It maybe a hardware issue. Please check the camera with stock ROM.

    Would this work with European firmware V12.5.1.0.RFBEUXM?

    Hello,
    Nice to see someone still supporting this device. I would like to understand if it is worth to me to move from my Xiaomi.eu ROM, and I have some questions:
    • How this ROM is different from the official LineageOS 20 ?
    • Can I root it with Magisk?
    • How it performs compared with LinageOS 18/19?
    • How it performs compared with Xiaomi.eu ROMS?
    When I had xiaomi.eu ROM I thought I had to replace the phone, as battery won't last a day. Now it's a whole different story.
    Faster, good battery life, same or better stability.
    Lineage OS 19 was about the same, with 20 you get Android 13 features, and fingerprint activation when screen is off.
    Didn't try official LOS.
    Magisks works without issues, just remember to unhide app while upgrading version

    LineageOS is a free, community built, aftermarket firmware distribution of Android 13, 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 20 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 13, 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-13.0.0-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.

    Thank you so much Kyasu for your hard work!
    I think I will wait a few weeks before flashing the new a13 build, just to see if it's stable enough to "daily drive" it.
    Clean flash recommended?
    Dirty flash over lineageos 19.1 is OK. I think this build is stable enough.
