Clearly many of the commenters here have not supported average smartphone users enough to know how they will blindly click the first thing that looks anything like what they think the technician is asking them to click. Remember, the average person does not have a laptop or desktop computer, they only have a phone (and only the one because they probably traded their old phone in with the carrier for a pittance when they got their current one), and they often do not have internet service at home and simply rely on mobile data from their unlimited data plan.
