    I did Bought a Samsung Galaxy Z flip 3 demo version , i want to build TWRP for it
    yesterday i downloaded the Kernel source code from Samsung , now i just need TWRP Sources and and Create a Device Tree to built it

    if you want TWRP for this phone , just comment down below (for some motivation)

    Now For a The Custom Kernel
    I Manage to Get A Custom Kernel Working with A lot Of Optimisations (Thanks @chrisaw and Others) on a Old OneUI (That System That Came with the Kernel) and it work well (it need some minor touches)

    the Kernel Cant Work on Newer OneUI and Custom Roms (Pixel EXperience) because Of new Changes in Vendor Are not Compatible with the Kernel
    A guess this Need A lot Of Working (Everytime Samsung do it their Way and Dont Care about The Correct Way)

    ScreenShot of the Kernel
    now on Focusing on The Custom Rom , i download LineageOS 19.0 Source Code as i will build for 2 separate phones (Galaxy Z Flip3 'snapdragon 888' and UMIDIGI F1 Play 'Mediatek Helio P60') consecutively

    this rom will be based on treble gsi patches but working only on Galaxy Z Flip3

    i manage to build LineageOS 19.0 for Galaxy Z Flip3 , i will not share it now cause :
    1 - it is not daily driver or usable , you can call it pre-alpha
    2 - it has a lot of bugs that i saw , it could be other i didn't
    3 - it is a Treble gsi just for testing purposes and does not have gapps (gapps needed to be included in the gsi not like a normal rom)
    4 - i fix the fingerprint , now it is usable
    5 - don't ask me about rear screen , it is perfectly not working at all (if you close the phone , the main display become black , rear screen have just samsung galaxy logo....)
    6 - other things i forgot

    Any Help will be appreciated
