In the first three months of 2012, Android continued its relentless march towards domination of the global mobile market, accounting for some 56% of world smartphone shipments (Source: Gartner). Its latest major OS version (Ice Cream Sandwich or simply V4.0) is gaining fast market traction with over 21% share, most of which happened in the last 3 months where it practically tripled its total share.
While Android is everywhere, it would appear that not all Androids are created equal. From a testing perspective, it is important to note the very broad distribution of the screen sizes and associated resolutions (see table).
