Sprint’s Galaxy S4 is about to get a whole lot better as the carrier appears to be ready to finally update the phone to the latest Android version available, Android 4.4 KitKat. After the kernel source was leaked yesterday, Sprint has posted confirmation that the real thing is rolling out to its subscribers. As usual, the update will be rolled out in stages, and it may take a while until all Sprint Samsung Galaxy S4 owners get their official KitKat build.
