You can also read it in 2015 Tim Cook's 3D touch announcement voice or Zu announcing the ZTE device with a 3D screen in 2017 or whoever at LG announced the wide angle lens, got meh to bad reviews about it, and then it took off afterward anyways.

My point here is I'm not saying it can't ever be something anyone would want because of that rather something selling in another device on Amazon has no weight one way or the other on whether it'd be a good thing to add to a phone.
