Mokee is one of the best custom ROM available presently.Few months ago, an app was released (known as WP internals) to root any windows phone and to install custom ROMs in them. So, if mokee OS does something to port Android (preferably the GO version) to Lumia 640, it will be a big boost to the users of windows phone ( moreover, it will give a new life to Lumia). Microsoft’s poor management team has destroyed the beauty of windows phones, and the last nail in the coffin is the end of support in March of next year. Moreover, dearth of important apps and incapable browser is forcing many to leave the platform. So, in the hard time for Lumia users, only an custom Android ROM can keep the device usable.
