IMPORTANT, PLEASE READ THIS
This is a ROM built from source and not a GSI!​

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 was failed. 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.

Video Review: if you want to see gaming performance and how this ROM are, you can watch this review video of the ROM in the J7 2016 (the ROM is the same for other Exynos7870 variants):

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

The ROM MUST BE installed with a CLEAN FLASH. So the problem is in you, that didn't follow the steps.

Also, i can't fix anything if you don't provide a logcat.

Why u changed the vendor? no sense. it's a ROM, not a GSI.

You can try if in LineageOS it's working fine for u.
So i will build crDroid 6.15 when crDroid release it, you can come back to this post in 20 days aprox to try this newer version.
anyway, thanks for try the ROM! :giggle: :giggle:

Sir, to replace the Live Display that does not work, I recommend this mini tutorial to activate the Google night filter, you just have to decompile the Framework-res, find the line you see in the image and replace the "false" with "true" , compile the framework-res and voila, you will see that in Settings the Live Display has been replaced by the night filter and the reading function is also activated.

Línea: <bool name = "config_nightDisplayAvailable"> verdadero </bool>
