Anyone that owns a T-Mobile Moto X, and participates in their soak tests, the Android 4.4.2 soak test update has started rolling out today. Of course this isn’t a major update from Android 4.4, which I am sure you already gathered. Improvements to the camera are the major features in this update, and of course the normal general enhancements. This will be build number 161.44.25, and should already be on your Moto X given you participate in these soak tests. If everything is runs smoothly with this Android 4.4.2 update, then the actual update will roll out shortly after. Let us know if you got it.
