The over-the-air update for the smartphone also gives its owners some "Wi-Fi Calling Enhancements" in addition to the latest version of Android.

Sprint began rolling out an update today for its customers who own a Samsung Galaxy Note 4 to Android 5.0 Lollipop. Actually, the update offers version Android 5.0.1 for those smartphone owners.
