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
Thank you for the feedback. I think I will move soon. The GCAM suggested by @kyasu is stable/working well? Do you suggest somethink else like opencamera ?

I use both. Gcam is slower, especially starting (up to a couple of seconds waiting) but works. Back in the thread you can find the link I used. Maybe others can suggest a faster edition?

Found several bugs. The vibrate on answer and etc options do not work in the dialer. There is also a problem when VoLTE is enabled, there are no beep tones when calling. Has anyone experienced this? Particularly interested in solving the problem with VoLTE

Thank you for the good work. Two questions, as I miss working location: Will location work only when Gapps installed, an microG is not (yet) compatible with Lineage OS 20?

I'm also having the problem with missing ringtone when calling someone with VoLTE. Apparently this is not a problem for everyone (maybe depends on the service provider's used frequencies?).
Unfortunately there seems to be no workaround, except to just disable VoLTE.
I have this problem in all custom roms i tried so far.

Xiaomi Mi 9 SE
Hi, updated yesterday from 19.1 with dirty flash, and I forgot to clean dalvick and the main cache, now Google Play says that I'm offline. Any idea what I can do about it?
PS:
I have already tried to flash gapps from the header, as well as reinstalling as a non-system application.

Strange problem for sure. Worked fine for a few days. Replacing with a SIM card from another operator did not give any effect.

I don't know where am I going wrong...
First, I clean the global version of MIUI V12.5.1.0.RFBMIXM via fastboot.
I'm flashing twrp via fastboot.
wipe(dalvik-cache-system-vendor-data-internal)
I open adb sideload from advanced and flash the rom.
I'm installing gaaps again via adb sideload.
When I say reboot system, twrp starts again and the system does not boot.
How should I continue?

i solved my problem. My bad.....

The solution was to wipe data after all the proccess ?

I forgot because I haven't installed rom for a long time. I was thinking that for format data, the data in the advanced wipe is meant. I solved my rom loading problem with format data next to advanced wipe. Like I said, my fault.
now i am looking for app and magisk module to force my installed apps to dark mode and edit aod screen.

i had the same problem. solution: go to google play app info (long click on app symbol) then click on mobile data and wlan and then you can activate network data.

    Ok i got it. It was always on display. Simply this plus forcing a bit the deep doze has fixed the issue. Battery tool in this matter is a suggested app

    This version is very slow to process and save the pictures in my device.way slower than gcam 8.1. did you encounter those issues too ?
    Yes, saving takes time, but I can accept that. Switching lenses is much faster and all in all it "feels" better.

    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.
