I'm using PixelExperience GSI.

Does updater work for you? I have two issues with it.
1) It stops the update when I move the app to background or when screen turns off.
2) When I make it run till the end, it says "Switched slot. OTA finalized.", but after reboot I get to the old system.
I tried switching the slot manually via fastboot but that didn't let me even boot.

EDIT:
I can't update via fastboot either. And I can't even flash the old one, which is weird to me. Is this a common issue?
Code:
PS D:\Downloads\test> fastboot flash system_b .\old_slim.img
Invalid sparse file format at header magic
Resizing 'system_b'                                FAILED (remote: 'Not enough space to resize partition')
fastboot: error: Command failed

If you experiencing any issues with the GSI roms
You can check my post on how to fix most of these issues i.e (LTE, 5G, Audio, Whatsapp audio , Auto-Brightness etc..)
It took me along time of testing and erasing my phone multiple times!

I'm using GSI PixelExperience_arm64-ab-vndklite-12.0-20220208-UNOFFICIAL. It's really working good and it's my daily driver.
The missing auto brightness could be fixed with the Velis Autobrightness App. It passes SafteyNet, too
DT2W is not working, but I use GravityScreen App instead.
It's a lot of work if you switch from MIUI to GSI, but it's worth it.

I've tested all other GSi builds, and I had only trouble. I stick with PixelExperience
Auto brightness is working if you flash gsi over miui 13 i flashed it over miui 13.0.1 and it is working fine

working:
-GPay
-Bluetooth
-5G, VoLTE, VoWifi (with fix)
-Stereo-Speakers
-Auto-Brightness (but better with Velis Autobrightness App)
-Fingerprintsensor
-Double Tap to Wake
-Camera (I use Gcam)

not working:
-raise to wake
-OK Google (because of Slim Version)

The Rom is working very smooth, no reboots and no issues

In "Settings/Phh Treble Settings/IMS features":
1) Install IMS Apk for qualcomm vendor (if you didn't do this yet)
2) Enable Request IMS newtork
3) Enable Force the presence of 4G Calling setting

In your Dialer app:
1) type *#*#4636#*#*
2) In testing menu open Phone Information
3) Set Prefered Network Type to anything including "NR" (NR = New Radio = 5G)

    The op not mention nothing about bootloader or custom recovery. Do I need a custom recovery? Do I need to unlock bootloader?

    Thanks in advance

    Booloader unlocked required. No custom recovery is needed though.

    Hello sir great explanation since this phone doesn't have custom Rom yet can you list any gsi Rom that available right now, thanks sir
    There's a link to Github in the original post.

    I'm personally using PixelExperience and aside of OTA updates it works great. I update manually via fastboot.

    Finally I found a better and perfect working solution:

    Pixel Experince SLIM works, because its under 3 GB. Here are my new steps:

    1. fastboot flash_all vili_global_images_V12.5.10.0.RKDMIXM_20211211.0000.00_11.0_global

    2. let it reboot to the setup screen and turn it off

    3. fastboot boot twrp.img (no need to install)

    4. update through twrp to miui_VILIGlobal_V13.0.1.0.SKDMIXM_e7e8f0ef90_12.0.zip

    5. it shows some errors, but it's still booting up to the setup screen. Turn off

    6. From now on: everything in FastbootD (fastboot reboot fastboot)

    7. fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img (see attached extracted vbmeta from MIUI 13)

    8. fastboot erase system

    9. fastboot flash system PixelExperience_arm64-ab-slim-12.0-20220221-UNOFFICIAL.img

    10. fastboot reboot recovery

    11. wipe data in Mi Recovery

    12. reboot and done

    13. for magisk you will find attached the pachted boot image from MIUI 13, and the extracted vbmeta. I flashed magisk in regular fastboot mode. Don't know if thats right, but it's working.
    P.S. everything was flashed into slot_b (didn't change anything)


    Now the screen brightness works, d2tw is working and it passes safetynet

    LineageOS GSI _ Vanilla edition.
    Everything is working flawlessly!
    Smooth snappy bloat-free OS
    Absolute win.
