LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github Repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

Fix Camera stretch & force close for some camera apps
You can do it editing /vendor/build.prop file using MiXplorer (you’ll need ROOT).
  1. Search for the line “vendor.camera.hal1.packagelist”
  2. After the = are the name of different apps. Delete one of these and put the package name of the app that you want to fix. For example, com.facebook.orca is the Facebook package name.
    • Per default, the ROM comes with Whatsapp, ZOOM, Snapchat and Instagram added. Maximum 4 Apps are allowed in this line and must be separated by comma ",".
  3. If you don’t understand, open this link to see visual steps.
Fix Camera stuck
Sometimes, the camera can get inaccessible if an app has crashed. If it happen, follow this:
  • Install this app. Open it and tap "Kill camera", then give it ROOT permissions. Done! Camera is working again.
    • Take in mind that if the camera is broken and you didn't do this, the audio in calls maybe not work.
GCam
This ROM can run GCam. Download a modded version for Exynos HERE. Thanks to Leonardo Estacio for his mod.

Games: this ROM works so good for gaming and can run ARM64 apps/games. If you feel lags, go to Settings > Battery > Battery Saver and performance > Performance Profile and set it to High Performance.

For close, i want to give a huge thanks to @Astrako - Without him this ROM haven't be possible <3

It´s been some time since I installed a custom rom, I was going to install this one.
But when i want to install the "LOS17.1-Repartitioner-exynos7870.zip", the fox recovery says that It failed to mount vendor.
What could I do?

After install the repartitioner, you need to go to the trash bin, then go to "format data" and type yes, then tap the tik in the below-right of the keyboard.
After this, go to wipe tab and select SYSTEM, CACHE, DALVIK, VENDOR, INTERNAL STORAGE and finally DATA. Then, swipe the bar.
Done, you can flash the ROM following the other steps!

I can´t even install the repartitioner, so Do I have to wipe everything you´ve said first too?
I´m coming from the stock rom, by the way.

Hi all. Mostly everything i tested so far works OK. Even cameras (front and back).

but i do have problem with sim cards not being detected. In settings i cant see IMEI and on each "sim status" i see "not available".

i have tried restoring Modem and EFS backup, with no lock. Modem backup restores ok, EFS fails. After sim cards still aren't detected.

Any idea what i can do to fix this?

I'm testing this on SM-J730F/DS with or without gapps.

----
EDIT: i fixed it by flashing latest stock room bootlader and modem (BL and CP). Following this guide https://forum.xda-developers.com/t/root-j730x-8-x-and-9-x-and-upgrade-bootloader-and-modem.3883139/
