Microsoft this morning began pushing out a new OS and firmware update for some Lumia 640 and Lumia 640 XL devices. Even more interesting, this update brings some new features including one for the yet-unreleased Lumia 640 on T-Mobile.
Unlocked and regional variants of the both devices should begin to see an update waiting for them on Microsoft's servers. The OS gets bumped to version 15148, which is a rather large jump from the current 15127 found on many Lumia 640 and Lumia 640 XLs. The firmware is updated to version 15184.36xxx.
