Agreed — but from the point of view of a private person, it doesn’t much matter what epithet you need to prefix the word “problem”, it still remains a problem.

From the point of view of a potential phone manufacturer, it also means that whatever you do and no matter how great your product is, very, very few people are ever going to use it at all unless they can use it in whatever they need to do; and that means you will probably fail as a manufacturer.
