After doing some digging and talking to some people, we can say that it will be either very difficult if not completely impossible for any phone that uses Qualcomm’s Snapdragon 800 or 801 to get an official, Google-sanctioned Nougat update (including the Z3). And that’s a pretty big deal, since those two chips powered practically every single Android flagship sold from late 2013 until late 2014 and a few more recent devices to boot.
This situation has far-reaching implications for the Android ecosystem. And while it can be tempting to lay the blame at the feet of any one company—Google for creating this update mess in the first place, Qualcomm for failing to support older chipsets, and the phone makers for failing to keep up with new software—it’s really kind of everybody’s fault.
This is such a cluster-fuck. Still.
