Lewa os is a ROM from Chinese. It is smoother than miui. As a matter of fact,lushenduan has already do it,but he can't make ota weekly. So I continue to make it. And it will become multi language in the future.
[*]Background when first installation (you need to reboot your phone once)[*]Video Record doesn't work if you selects Samsung camera(You can use aosp camera in the ROM)
