Sprint has released the Android 5.1 Lollipop update for the Samsung Galaxy Note Edge handset, making it the first carrier in the U.S. to release the Android 5.1 update for Note Edge users. It has also released minor updates for the Galaxy S6 and the S6 Edge handsets.

The Galaxy Note Edge flagship comes preinstalled with Android v4.4.4 KitKat. At the beginning of the month, Verizon released the Android 5.0 Lollipop update for the Galaxy Note Edge and now Sprint has released a newer Android 5.1 build for its Note Edge users. Sprint had already updated the Note Edge to Android 5.0 Lollipop three months ago, Phone Arena reported.

Since the Android 5.1 is an incremental update, it does not bring many new features to the Note Edge handset. However, it fixes all the major bugs that came along with Android 5.0 Lollipop OS. The official Sprint page does not list the features that arrive with Android 5.1 with build version N915PVPU4COFE.

Phone Arena said Sprint has also rolled out minor updates for the Galaxy S6 and the Galaxy S6 Edge. The update for Galaxy S6 installs the G920PVPU2BOFE. On the other side, the update for dual-edge screen variant installs the G925PVPU2BOFE build. Sprint says the newer updates for the new Samsung flagships are aimed at fixing bugs and improving performance

Sprint is selling the Galaxy Note Edge with a two-year contract for $429.99. AT&T has recently slashed the on-contract price of the Note Edge phablet by $200. It is now selling the handset for $199.99 with two-year contract. Also, the two-year contract price of the Note 4 is discounted to $99.99

Speculation is AT&T has reduced the prices of Note Edge and Note 4 to clear the inventories of these models to make way for successor models like the Note 5 and Galaxy S6 Edge Plus in the near future. Sprint and other U.S. carriers are expected to lower the price of their Note 4 and Note Edge handsets very soon.
