You are complaining about a phone you don’t even own. You say the Camera Button is a button and feature nobody asked for. You then go on to say that you plan on buying the 17 PM, which you know nothing about and hope the Camera Button is improved. How in world can you come to the conclusion that your OP and this retort to me are congruent with one another and more importantly, logical? Between your OP and this post, you have contradicted yourself.
The Camera Button isn’t really what you are complaining about. The real problem is your false expectations of Apple tech reality. When Apple didn’t deliver a phone that spec wowed you, you found yourself an illogical tech catch phrase to hang your purchase excuse on.
