It seems almost unanimous: iPhone users want a somewhat larger screen, not huge like the Galaxy Note but a display that is around 4 inches.
The designers take advantage of the wishes of the users and the rumors that are filtered by the network to create concepts of future iPhone generations like the one you see in the image.
The design of this concept shows us a iPhone 5 (or new iPhone) exactly the same as iPhone 4 and iPhone 4S but cwith a screen in 16: 9 format and another in 3: 2 format but with a diagonal of 3,84 inches and 300 dpi.
Personally, after testing a 4-inch phone and a 4,3-inch phone, I think that Apple should take the leap and abandon 3,5 inches which in its day allowed it to distinguish itself from everything that was known until the arrival of the iPhone in 2007. With 4 inches, usability is maintained and the user experience is considerably improved.
Would we have to sacrifice pixel density to avoid application fragmentation? Yes, but you can't have everything.

To know how an iPhone with a 4 ″ screen could be without losing the 3: 2 ratio, nothing better than to look at the Meizu MX.
