The Android 4.4.2 update is hitting yet another version of the Samsung Galaxy Note 3, this time on T-Mobile. The update clocks in at 495.74MB and will be the first significant update to T-Mobile's Note 3 since release late last year.
T-Mobile has yet to update its official support docs with a changelog or OTA status, but we've already gotten a few tips that the OTA is rolling out. Check the update menu to see if you can manually pull it down, otherwise it shouldn't be too long. In addition to the UI tweaks, the KitKat update should enable Tap and Pay in Google Wallet.
Update: T-Mobile has updated its support docs with some details. The new build is N900TUVUCNB4 and should be rolled out to everyone automatically by April 11th. The update is also available through Kies.
