I installed it last night on my ancient galaxy j2 pro. Everything is working great expect that the ROM cannot address more than 1.5gb of ram even though my j2 pro has 2gb ram. Is there any way to fix this?

no... as this ROM was made for the J2 2016 1.5GB ram version

the internal ROM software itself doesn't know your phone has 2GB ram

Can we have android 10 rom ported for smj210f. Android 10 is a lot better in terms of customizability.
android 8 is possible... because someone already made android 8 for a phone with SC8830

I don't think so, since it's not from the j series.
May be can we port this' lineage-15.1-20180708-UNOFFICIAL-core33g.zip' for J2 2016??

[ROM][8.1.0][SM-G360H/HU] LineageOS 15.1 for Samsung Galaxy Core Prime
porting upstream is impossible.

however I do think it is possible to compile the rom by using that tree as a big base
(very possible in fact. because everything aside from the screen etc is a carbon copy of our device)

maybe use cloud storage for uploading unwanted data currently and free it. Also can you port or make oreo custom rom with picture in picture feature ? Is it possible right now for this phone?
compiling lineageOS 15 requires 200gb at minimum... even if my laptop was fully empty, I would still not have enough storage
I got 8GB RAM and the only limiting factor is my CPU (i3 5th Gen and another laptop with i5 4th Gen) and my HDD. I have 400+GB storage free.
hmm the CPU is a problem. i think those are too old

    Thank for the port Nullcode🙏
    stable rom and it's working good
    Brightness cannot be adjusted & there is no volte option please fix these also

    To fix brightness, you need to go to Settings: Display: Brightness and turn off Auto Brightness
    That will fix the problem

    If that doesn't fix the problem, Download and set up Platform Tools from Google, connect your phone and type this command:
    adb shell settings put system screen_brightness_mode 0

    Also about VOLTE, it cannot be implemented in custom ROMs
    Only stock ROM has that feature
