While it's certainly not the mainstream set of priorities/preferences, it is possible for someone to have a set of priorities in a phone that precludes the high end cameras, while still wanting a very good camera. And depending on the weighting of those preferences, they might be willing to put up with the inconveniences you outline. It's obvious that you peronally don't share those preferences, which is completely fine. But it doesn't make sense to criticize someone else who does. There are sets of preferences where it is not possible to satisfy all of them and something must be sacrificed. Some people will choose to sacrifice convenience.
