As people on reddit have pointed out, there are two problems with this article:
1. It's inaccurate to call them "fake towers" and put up a picture of a tower, because this suggests someone is installing large-scale fake infrastructure. They are actually interception devices that could be quite small and running out of a little room or a vehicle somewhere.
2. The article has rather too many plugs for a particular model of "hardened" Android phone. Someone somewhere has been lazily recycling press releases.
With those two caveats, the concern about someone spying on our cellphones is legit.
