no need to flash that rom. just flash the quantum kernel.
Well that depends on which rom you flashing it to cause it doesn't work on tree ui. when I flash it it only go into bootloop and I haven't found a way to make it work and since i can't play Genshin Impact on it I had to switch to havoc os 4.4 or any other custom rom or stock android 10 rom and that's a bummer. As of right now I got havos os to work with root and later on got corvus os 16.5 beta to work on my a7 2018 gn/ds device with root and it has been my favorite experience so far and basically everything works. my daily driver rn and works with quantum kernel too, so you get dual speaker, face unlock and fingerprint working pretty well and the rom itself running really smooth havoc os 4.4/corvus 16.5 beta.

After using this rom for about two months on my galaxy A7 here is my expereince.
I faced major kernel issues, the memory management is terrible and the phone starts to get very slow if I'd try to multitask.
The lack of samsung camera is a pain but it's not that big of a deal, the major issue is the camera drivers. They seem a bit off and some apps can't use the camera.
Audio jack has some stutters here and there and will output loud noise at times, restart will fix it though.
PC file transfer using cable is also way too slow.
It wasn't all bad though, the battery life was better than the stock rom.
Overall a fun rom to try, and I really appreciate the work that's been put into it but I think it really needs some work on the kernel and driver department to be considered daily driver ready.

@VDavid003
Can we expect fixes for bugs mentioned so far in this thread to use this ROM as daily driver?

Although, I'm on it since last two months but considering to switch back to stock.
Reboot on unlocking and network outage intermittently are forcing me. Many a times, If I pick the voice call up too early, there is no audio but call continues.
As far as camera is concerned, the best GCAM I could try on it was PZDv2. Although, photo can't be saved, but video recording works on both cameras. Playground photos can be saved but with lower resolution. Stability is better than other GCAM ports.

@AgentMyrie47
Can we use/access wide camera on havoc/corvus os?
What about samsung security features like "find my mobile" and fingerprint authentication on financial apps?

Tried it for the past two months now , everything is working fine exept those :
-Random loud noise occures during playback remove the headphone jack will fix it.
-Bad ram management (laggy when playing games).
-No stock camera.
-In the game plugins ,PerfZ is not supported (Supported in stock firmware).
-Gpuwatch doesn't work.
It's a great rom overall but needs to be fixed .

I am using this ROM for a few weeks now and everything seems to work great. I only notice one problem, which is that when trying to encrypt my phone, the phone gets stuck in the Android image (the image that is displayed when starting the encryption) and it does not seem to work.

Does this only happen to me? Is there a way to repair it?

My model is SM-A750G

    (No, the ROM has nothing to do with trees, it's just OneUI 3)
    Welcome to Android 11, and OneUI 3 from the Galaxy S20!
    This ROM is a direct port of OneUI 3 from the Samsung Galaxy S20 to (parts of) the Exynos 7885/7904 family.
    It can be used on Treble and Non-Treble phones. If you use it with treble enabled, it will install a vendor compatible with Android 11 GSIs too!

    Features
    -Based on G980FXXS6DUBA
    -AROMA installable modules, and CSC selector
    -DeX On PC Works!
    -Debloated base

    -TreeUI Kernel with 4.4.185
    -Includes Android 11 vendor (Full vndk, works with vndklite too)
    -Support for A530F, A530W, A530N, A730F, A750*, M205*, M305*

    What doesn't work:
    [Common]
    -Samsung Camera (3rd party apps should work)
    -Face unlock
    -Torch intensity control
    -VoLTE (experimental option available, some Indians had luck with that, and DBT CSC

    What works:
    -Everything else

    Installation:
    Read this as you need to set some settings to fix the resolution and DPI

    -(Optional, A8 only) Treble your phone using the treble guide
    -If you haven't yet, install a custom recovery and decrypt data
    -Flash zip in custom recovery
    -Wipe data
    -Reboot
    -First boot will be in wrong resolution and DPI
    -After setting up the device, go into display settings and set the resolution to 1440p or 720p
    -Set it back to 1080p
    -Set display zoom to some other level then back.

    Downloads/Changelog:
    0.9.5 BETA (ROM+VENDOR) (note that a beta test version of this was leaked with many of the problems not fixed. please update if you use that leaked version)

    Hi, I've flashed this rom on my a750f using PBRP recovery and I'm getting bootloops. If any of you guys successfully installed this rom on your a750f device, can you please specify the custom recovery, security patch and method of installation that you used?


    Edit: I fixed it, if anyone faced the same issue, rollback your official rom to the earliest android 10 rom you can find, then install twrp from this thread using instructions provided there, and flash the rom using the instructions provided by op. works perfectly fine, Amazing rom.

    Secure wi-fi is broken.

    Lost some features like Samsung Pass, Samsung Pay, Secure Folder. (Knox issues due to bootloader unlocking)

    Edit:
    1) ADAPTIVE Eye-comfort-shield doesn't work.
    2) Motion smoothness 120 Hz @ 1080p doesn't work. (Hardware not supported)
    3) Samsung keyboard Handwriting feature gets disabled after first keyboard call.
    4) Enabling fingerprint and dual messanger both doesn't work simultaneously.
    (Either continuous reboot after lockscreen or secondary social account crashes).
    5) fingerprint authentication doesn't work in some financial apps but works in some others.
    6) samsung account interferes with almost every screen lock method(even after disabling find my mobile). Unlocking causes random reboots. After setting locking method, and then removing lock to no/swipe security, phone goes into lockscreen again automatically. Only solution to overcome this is to flash rmpass.zip using recovery.
    7) network outage occurs in both the sim randomly during heavy data uses (not frequent), but can interrupt non-resumable downloads/financial transaction over website/apps.

    (After factory reset, handwriting mode button get activated momentarily in samsung keyboard. Screenshots attached here. But while tried to download handwriting data, it failed. Tried downloading using mobile data and wi-fi both. )
