minimal changes, why? maximize profit. Every additional year a company doesn't need to make dramatic changes to a fabricated product means the company maximizes profit, especially if prices stay the same. Samsung does the same as I'm sure every other phone makers. Fortunately Samsung is one of the only companies that innovates and offer true alternative products. This is why I switched to my first Note after 6s+. Now I'm sporting a fold 4 and loving it.
