    Some known issues :
    1. No charging when the device is off
    2. Some people also told that GPS is not working but some said it's working
    3. Random reboots while we are using internet on mobile data for long time (over 1 hours or so)
    reboot problem?
    Dev an i use this rom for sm-j200g??,

    This is only for the J200H and won't work on any Exynos Galaxy J2 model, like the J200G.
