This rom is very nice and working fast then stock rom
Only one feature is missing that is secure folder..
Can you add the secure folder feature in next update please..
Thank you very much for this latest rom for A8+..
And also please give some instructions on how to change csc code for other country because I'm from india and i want to use INS code so please let me know how to change that..
How do you use dex with this?

If using a PC, install the desktop software. [ Windows 7 & 10 ][ Mac OS ]
If connecting directly to a TV or monitor, you'll need a USB-C to HDMI cable.
If you don't have a cable, you can still connect over the network.
--> Make sure wifi and bluetooth are enabled and both devices are connected to the same network.
--> For best results use the same 5Ghz network.
Note that depending on the device you use, you may need to enable developer options and and poke around to enable DeX.

Once you're setup as described above, navigate to your phone's Advanced Features menu, and enable Samsung DeX.

    (No, the ROM has nothing to do with trees, it's just OneUI 3)
    Welcome to Android 11, and OneUI 3!
    This ROM is a direct port of OneUI 3 from the Samsung Galaxy M31 to the Galaxy A8/A7 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!

    -Based on M315FXXU2BUC1
    -Slight debloat
    -OneUI Core 3.1
    -TreeUI Kernel with 4.4.185
    -Includes Android 11 vendor (Full vndk, works with vndklite too)
    -Support for A530F, A530W, A530N (seems broken, please someone that can debug, contact me), A730F, A750*

    What doesn't work:
    -Samsung Camera (3rd party apps should work)
    -Face unlock
    -Torch intensity control
    -Jack has some faint noises while no media is playing

    What works:
    -Everything else

    -(Optional, A8 only) Treble your phone using the treble guide
    -Flash zip in custom recovery
    -Wipe data

    - NFC Fixed on A7 (Thanks, @Voytec83)
    - SSRM warning removed.
    - Bluetooth fix readded.
    - Kernel zram tweaks, and Wireguard support
    - Fixed installation on modern non-treble TWRP
    - Updated system to OneUI 3.1 (M315FXXU2BUC1)
    - Added initial Galaxy A7 support (thx for the testers!)
    - Removed FaceService as it was crashing constantly.
    - Fixed updatable apexes (Google Play System Updates)
    - TreeUI Kernel is now 0.9.3
    - Added CSC stuff (defaults to XEH for now)
    - Fixed WiFI Hotspot
    - Partially fixed jack connector (there is some noise while no media is playing)
    - Fixed Device Care (but the fix does give you a popup every time you restart)
    - Fixed Vulkan
    - Debloated some Samsung camera stuff
    - Added support for A530N (Korean A8 model) Broken? Please someone that can debug on A530N, contact me!
    - Added separate vendor only version
    - TreeUI Kernel is now 0.9.2
    0.9.1 BETA (ROM+VENDOR)
    - First public release

    Source Code:

    -@prashantp01, and @ananjaser1211 for lots of fixes, and help! Go support them!
    -@arminhere, @Hovo01, @Voytec83, and @VenusEleven for testing!
    Not available... Please develop version of SM-A530N...
    That's the korean model, right? Will try adding basic support soon, but if my assumptions are correct, it should work fine with the A530F version until then. (You'll have to modify the updater script, so it actually installs on A530N, just look for any text saying A530F, and replace it.)
    Please test it when I add support later, as I only have an A530F!
    Thanks, I know :D
    Hey, appreciate the ROM, just had a question:
    Is the s20 one or the m31 one better?
    Depends, S20 definitely seems smoother and is more feature-packed, but you lose VoLTE for now if that's important for you.
    Oh, I also found that hotspot don't work neither 2.4 nor 5.0 GHz modes.
    That's a phh issue, I told phh about it and made a pull request that he accepted. Next release will have a fix, until then you can do `setprop persist.sys.phh.system_hostapd false` in a root or adb terminal.
    Great work.. I'll try the stable build for sure.. Thank you... :cool:;)
    BTW, I love this build cz the Samsung Dex is working fine for me 😍
