Over the last couple of weeks it has been rumored that Google had began internally testing Android 4.4.3 which would focus on fixing multiple bugs in the KitKat version of Android. Some of these improvements should include issues with battery drain and camera improvements.
Below you can find Sprint’s official change log which includes a Sprint specific software addition but also a generic statement about an Android update.
We do not know for sure that this update will include 4.4.3 but we have no other idea what “Android updates” could mean. As soon as we know more or have a download link, we will share it with all of you!
