Today I have seen a lot of Buzz going around on Nokia X Threads and extracted this Apk file from the Nokia X System apps and tried installing it too on Galaxy Grand, Guess What ? "The Launcher Stopped Working" for I ran it. Maybe there's something wrong with the resolution, maybe it needs for modification to use it on other devices.
So, I was looking for a Dev who could understand this APK and edit it and see if he/she can make this Launcher.apk as a working apk for almost all devices (if possible). See if anyone can fix coz some people want this Launcher on their device (including me )
