They need to offer a flagship without the curved sides so one can put a real case on it. My wife's s7 had one of those kinda cases that wraps partly around, but the screen still shatter when dropped 2 feet and hit on the corner.
Now with her s9+ she had to go with another case that doesn't really protect the front, so she insisted on the durable case like screen protector cover for the front...well, now the screen isn't very responsive at all, and makes it really frustrating crippling such a powerful device. And, the edges serve no purpose other than to look cool when not in case, but...it has to be in a case or else it will almost definitely have a screen or rear glass back break.
