T-Mobile recently started pushing out a new update to HTC 10 units on its network. Arriving as version 2.41.531.44, it’s a minor update that brings some system enhancements as well as the April Android security fixes.
Nothing else is included in the update. As is usually the case with OTA roll outs, it might take some time for the update notification to pop up on your device’s screen. Meanwhile, you can also manually check for the update by heading to your handset’s Settings menu.
