I’ll never understand this question. Other than making it thicker to allow for a larger battery, lens rearrangement that might allow for everything to be flush, what needs to be changed?
We’ve had round edges, to square, back to round and then square again. Should they try octagonal or triangle edges? Maybe a triangular phone.
Technology with better cameras make for massive bumps. Make the phone super thick and everyone will call it a cinder block instead of just a brick.
Design is fine. JMO. 👊😃👍
