T-Mobile has started to push another Android 4.4.2 update on Samsung Galaxy Note 3 SM-N900T and Galaxy S5 SM-G900T. The OTA update is now available via over-the-air and being dubbed as N900TUVUDNF4 for the Galaxy Note 3 and G900TUVU1BNG3 on Galaxy S5. According to T-Mobile’s support page the update will bring some improvements to the VoLTE support, which already sent out from previous 4.4.2. So better check it out now, but do not expect any major changes once you have managed to update your device as the statement clearly says that it will Turn on the Voice Over LTE and Network Improvements.
Customers already on VoLTE software will be notified of the OTA software update. Customers not on a previously released VoLTE software will have to manually request the update via Wi-Fi due the file size. The update will be available for manual update via Samsung Kies on the same day.
