I HAVE A LIFE OR DEATH PROBLEM, when using NFC it gives me the error "The card could not be read" Something like that. It is literally one of the only things I see in a rom, if it works NFC, Battery, and 64 bits. This rom is perfect and I don't want to let it go but I really need NFC to load my card for public transport, I would really appreciate the help.

the custom ROMs I know for J7 2016 unfortunately have errors, as a daily driver with bluetooth-calls and speaker-calls "stockrom-flashable" might be the solution, for NFC possibly also... ;-)

Thanks for replying, I don't use the HTTP CUSTOM app so much for the vpn but to connect to unlimited internet, I don't know if you know that but with that app I connect and it just doesn't work in this rom, but you made me think, maybe it's the gapps, why install another aosp rom, with the same gapps and it doesn't work either, maybe that's it, you don't know of other gapps that work for this rom in j7 neo, thanks in advance

Ever tried without GApps? we download our apps via F-Droid. the apps we don't get there, we get via Aurora app from Google Play Store.

All phone contacts we back up with the contacts app as vcf file regularly on the device and send them via eMail to ourselves to back them up additionally on the PC.

Hello friends. nfc is working normal on my j710mn. with this rom I did a test yesterday and it worked normally so this must be an error that could be due to an error in the device or in your wallet app. try to use google wallet app that is working normally with this rom

    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
