The upcoming Android 4.4 KitKat update for the T-Mobile Moto X has been leaked ahead of its official release. It comes less than a week after Google announced KitKat’s release, and early reports suggest it works surprisingly well.

It’s not often we see a leaked update like this — especially one that works well — so soon after a new Android release is announced. But of course, now that Motorola is owned by Google, it’s likely the company started work on this long before KitKat got its official unveiling alongside the Nexus 5 last Friday.

According to early reports on the XDA Developers forum, the update is “nearly fully functional,” and as long as you perform a full wipe before installing it, you shouldn’t run into too many issues. It’s not quite perfect, though, so proceed with caution if you rely on your Moto X day in, day out.

It’s also worth noting that the release hasn’t been available very long, so there could be some bugs that are yet to be discovered.

If you still want to try out the firmware for yourself, you’ll find the file and more details on it over at XDA by following the source link below.
