Did you flash reparationer? If yes which recovery are you using?
Maybe my device does support 64 bit, I do nt know, it is galaxy J710f ,I think it does
I tried many ROMs , but now I prefer android 8 to use original xposed . If you have stable ROM android 8 please share it, want to change my unstable ROM, I cannot tweak GPU and CPU the system take over

Sorry I don't have any android 8 ROM... I m on J710 FN and I use Nevaos ROM because it is the only ROM I found without voice echo for my correspondents when I'm on speaker. I installed lsposed with magisk and could get gravity box working to have some additional good features. If you can just give it a try

j7xelte: My wife uses crDroid v6.21 since August as her daily driver and is very happy with it! no gapps, we use Aurora and F-droid.
K9-mail, signal-messenger, phone-calls, music via bluetooth-speakers worked perfectly, only camera crashes occasionally and voice-recording is very quiet,
battery life is excellent, flight mode overnight only about 1% battery drain

- next security patch?
- where can we download GCam modded version for Exynos (Leonardo Estacio), we don't use Telegram.... Thanks!

    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.
    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
