Sprint has confirmed that it's rolling out Android 4.4 KitKat firmware for the Samsung Galaxy S4 and Galaxy Note 3, with both updates having gone live in the past month. Sprint's Galaxy S4 started receiving KitKat from Feb. 13, and was joined a week later by the Note 3 on Feb. 20.
It appears Samsung is planning on releasing a new Galaxy device soon that will don the EXYNOS 5250 1.7 GHz Dual Core processor. It looks like the device will be in the mid-range tier, although the specs is tinkering its way into high end status. The device will have an HD resolution (1280 x 672) screen and will launch with Android 4.1.1 Ice Cream Sandwich.
