The Moto X Force runs Android 5.1.1 out of the box, with Motorola’s slightly tweaked version of stock Android on top. This is a major disappointment, as users would expect a company like Motorola to launch its newest flagship phone with the latest version of Android. Although we can expect software updates, there’s no official word on when just yet.
The user interface is pretty much identical to stock Lollipop, although updating the default Google Now Launcher brings a few Marshmallow-esque changes to the interface.
