Update: Build KTU84F will hit devices between today and April 21st. Sprint hasn't fixed the typo on its support page, but the forum post has the build right.

What a day for an OTA – specifically, Android 4.4.3 for the Nexus 5. Sprint has updated its support page to indicate KTU84F is dropping today, which we understand to be the rumored 4.4.3 release. There is a Sprint-specific tweak in this update, but the software should also be hitting N5s that aren't connected to the Sprint network at the same time.

The changelog is pretty straightforward. Here's what we've got.

The information we had previously said Android 4.4.3 was mostly bug fixes, so that's probably all bundled in with the "Misc Android updates." Sprint users will get access to Sprint Spark with this OTA. The device already had the hardware support for tri-band LTE, but now it's being enabled. Also note that Sprint typo'd the build number in the original post – it's going to be KTU84F.

If the OTA breaks cover today, we'll probably be able to find the download URL for manual updates. Just hang tight if you simply must be on the latest and greatest.

[Sprint – Thanks to everyone who sent this in]
