Apple usually prides itself in how manageable its phones are with one hand, and this still holds true for the iPhone 6s, despite that it has unremarkable screen-to-body ratio, mainly because the screen is 4.7 inches, which is pretty modest for today's smartphone standards. The company has also shown that it won't shy away from the trend for larger phones, however, as exemplified by the 5.5-inch iPhone 6 Plus and 6s Plus handsets.
Moreover, recently we had a reputed analyst saying that Apple could introduce changes to its circular home key that may be iconic, but takes quite a lot of valuable space in the front. Could Apple try to shoot for a better screen-to-body ratio and/or a larger screen with the iPhone 7 then? If so, what do you think would that screen size be? Take your pick from the poll range, and tell us the exact diagonal you predict in the comments below.
