The article is chiefly about a radio circuit you can "build", plus some controller software that happens to run on an Android phone. Meanwhile the headline is 100% focused on describing something that your phone can be made to do (which you have admitted that it can't).

The two don't add up, and your apologetic analysis doesn't convince me otherwise. It's still clickbait. An Android cell phone has radio guts, and that headline is just gutless.
