Android 4.4.3 rolling out to Sprint Nexus 5 devices

Android 4.4.3 rolling out to Sprint Nexus 5 devices
The rumors for an Android update have been pretty regular the past couple of weeks. In late March, we caught wind of a new build number beginning with KTU8, lo-and-behold, Sprint announces KTU84F will begin pushing out today.

If you are the type of person who waits for such notifications, you should see yours over the next few days. Aside from Sprint-specific “tweaks,” this is the rumored 4.4.3 update to fix a number of bugs that have been frustrating Nexus 5 users.

Chief among those frustrations would be issues related data connections as well as problems with the camera. In addition to those, the rest of the list, as far as we know, is a standard rundown of bug fixes. Wi-Fi auto-connect should work better, MMS performance will be improved too. The benefit from these fixes should translate to better battery performance.

Email performance, particularly for those connecting to an Exchange server, should see a fix along with the calendar. There will undoubtedly be some security enhancements as well. We are not being more specific only because Sprint’s own announcement merely says, “Misc Android updates.”

It does seem a little unusual that we would see a carrier update ahead of the regular Nexus line of devices directly from Google, but if anything, that means we should see updates across the board in fairly short order.

If you have a Nexus 5 from Sprint, or a Nexus 5 in general, let us know if and when you get the update.

Carriers don't push out updates for Google devices. Google does.

If its a Sprint update it could enable spark on the device. That would be just about the only worthwhile carrier update.

The update does enable spark but the update comes from Google not Sprint, so Nexus handsets will receive it at around the same time, there is no Sprint variant of the Nexus 5, you can switch from the carriers as you wish

The american version of the Nexus 5 is a Sprint compatible devices. The only situation that some user have is the nexus 5 is a spark compatible devices, but Sprint, neither google has activated de Spark compatibility. Also, Sprint sells the 16gb version of the nexus on the stores and online. So, check the info first...

You dont want spark just yet. Data + cell = no worky data until you end call.

From the AP article: "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"

Sprint has a good sense of humor at least.... I'd love to know who picked "happy connecting" as their slogan on these web ads... HAHAHAHAHA. I think they meant "good luck connecting."
