  1. Brother, can you please fix the voice call volume issue or just provide us with a patch…? All your roms are great but the most important functionality of a phone, that is calling, and that’s getting issues. Also, i noticed frequent network drops while driving… Hope you’ll fix it soon. And again requesting you to please provide a patch for voice call volume issue.

  2. Hi there Ranjan, thank you for this ROM. Can I ask some questions? My device is currently running in EU ROM with TWRP installed and i wanna try that ROM (Cardinal OS) do i still need to replace my current custom recovery to the custom recovery you posted above? Or what? And my device is running on Android N EU ROM beta. Do I still need to flash the firmware v28?

    • Yes, latest twrp recovery version required to flash oreo roms. Also, it’s better to upgrade the firmware as well to avoid the bugs and compatibility issues.

  3. Thanks for yet another great rom. I found two bugs I hope you can look in to them.
    1. SuperSU doesn’t work properly (magisk works perfectly though)
    2. I got random message that config updater has stopped. I don’t know what that means. Can’t get logcat because it’s random.

  4. Хороший Rom, но у меня меньше резервных батарей по сравнению с другими ПЗУ.

  5. There is a missing feature which I want Ghost team to add it.In this feature, only the user can access recovery mode(twrp) via advance restart.Manual boot to twrp must be stopped i.e through volume keys and power button.This will really help in case of theft.Lineage Os has this feature but it is not battery friendly. Please Ghost Team,add this feature if possible. Thank you.

    • sorry sir me suffering from typhoid since few weeks so unable to answer anyone can you ask the question again if you don’t mind please
