Switch to 48MP, Macro Mode and NightScape in OOSCam doesn't work(ROM Specific issue, can't be fixed atm)
Due to NightLight FOD, the normal Night Light feature gets conflicted and doesn't work. So if you want to use Night Light, turn off NightLight FOD from Xtensions Settings(Known issue from rom source)
