Sprint's support docs for their version of the Moto X Pure Edition have just been updated. Apparently, a new update is heading to that phone. Sadly, Sprint didn't get too specific on whether the update is Android 6.0.1 or is just a security and performance patch. Of course, we are crossing our fingers that it is both!
We will keep you apprised if we hear more. In the mean-time don't forget to drop by our dedicated Moto X Pure Edition section for more discussion: Moto X Pure Edition
