According to the Sprint the new KitKat firmware update will start rolling out for Nexus 5 manufactured by LG marketed by Google from today.
The Sprint added, this firmware update will enable Sprint Spark on Bands 41 and 26, alongside giving “many Android updates.” The Android KitKat 4.4.2 build number to watch out for is KTU48F, and since Sprint’s SKU is indistinguishable to the U.S. unlocked variant, all Nexus 5 owners will be able to update their device to Android KitKat 4.4.3 via OTA (Over the air).
It is more likely that this is the earlier announced Kitkat maintenance update, which will mainly gonna fix Camera issues which we was facing after earlier KitKat update and other different issues has also been solved— and probably this will warrant a knock in version number up to Android 4.4.3. That means we could be seeing this new Android form across over different Nexus smartphones before too long.
Apart from the Camera fix, here are the other bug fixes that are included in this Kitkat OS update such as Frequent connection drops with mobile data; App shortcuts security issues; Bugs in calendar,DSP errors; HDR mode issues; dialler and people apps; Power manager display wake up lock; Malfunctioning of Wi-Fi auto-connect; Missed call LED; Regularize camera focus; Multiple Bluetooth problems; contract, Random reboots; USB debugging security issues; Other known bugs plaguing the camera app; Inaccurate data usage graph; Issues with email and MS exchange sync; and IPv6 and VPN network issues.
To manually check for this update go to your Settings->About Phone-> System Updates. If it is not showing any update then wait for some time and try again, you will get the update for sure.
