Sprint HTC One gets minor update
Sprint's version of the HTC One has just received an update, but it doesn't change the OS build which is already at Android 4.1.2. What the update does do is add improvements to the aforementioned BlinkFeed and adds a new Sprint Zone client for the phone. Lastly, the update also improves the sensitivity of the Back and Home keys.
The update will hit your phone OTA or you can try to pull it out manually by going to the home screen and tapping on All Apps>Settings>System Updates>HTC Software Updates>Check now. Follow the directions for downloading and installing the update, which brings the software version to 1.29.651.10.
