Android 4.4.3 hasn’t been officially announced by Google yet, but we’ve gotten a few hints about the next KitKat update and what it may contain. Today Android 4.4.3 is back in the news thanks to a leaked Samsung document that shows which devices are currently being tested with the rumored update.

According to an alleged Samsung document shared by SamMobile, Samsung is testing Android 4.4.3, build number KTU70, with the LTE-Advanced Samsung Galaxy S 4 (GT-9506A) and both the Exynos (SM-G900H) and Snapdragon (SM-G900F) versions of the Galaxy S5. Both models are listed as being in the “Integrating” phase of the update process.

Since Google hasn’t officially announced Android 4.4.3, the update’s official list of changes is still up in the air. Since it’s an x.x.1 update, though, it’ll likely a bug fixer. The rumor mill suggests the same, claiming that the update will include goodies like Bluetooth fixes, camera fixes and a Wi-Fi auto-connect fix.

There’s some good news today for owners of Samsung devices other than the Galaxy S 4 and S5 as well. A separate leaked doc shows that Android 4.4.2 (HOT49H is being tested with the Galaxy Grand 2, Galaxy Mega 5.8 and Galaxy Mega 6.8 and is also “pending” for the Galaxy S4 mini LTE and Galaxy Note 3 Neo. The Grand 3 Neo is slated to receive its Android 4.4.2 update sometime this month, while the S4 mini LTE, Grand 2, Mega 5.8 and Mega 6.3 should be treated to 4.4.2 in June.
