Androphones and large screens, step and a history of size

You ask why Android smartphones have large screens? Here are a few elements of answers...

It is true that in the world of smartphones, those running on Android have seen their screens diagonal grow exponentially, from 3.2 "to even" 4.65 "5 for Galaxy Note.

And this is not that a marketing will that it is great over it in "casts" and attracts the consumer, but also a question of readability and ease of use of graphical interfaces.

Indeed, there are so many models of androphones to handle each with their size and their definition of screen - diagonals of 2 to 5 "and 320 x 240 pixels to 1280 x 720 pixels - that Google had to publish a"Android Design"guide to mobile applications designers destination.


Mountain View firm explains that important to take into account is the resolution of the screen must be close to the 320 DPI (pixels per inch) so that buttons and other interface elements is not tiny and remain legible and manipulated easily on a maximum of terminals.

Thus for a definition of 1280 x 720 pixels 320 DPI, the better diagonal is the 4.5 "minimum, and to the 960 x 640 as the iPhone 4 for example, the 3.5" current is ideal because combining display quality and maximum readability while allowing to keep a certain compactness on the apparatus.

It is therefore a question of compromise between definition, resolution and screen size and not just a history of who has the more diagonal grande… to screen of course.
