Google have decided to stop providing security updates for older Android Operating System devices, which could account for 60% of users, over a billion mobile phone and tablet users. There was no official announcement to notify all the users affected and suggest a way forward.
A smart phone operating system (OS) is essentially the software that provides the “brains” for a device that makes the phone “smart”. Like a book without content, a mobile phone without an operating system is not much use.
Android phones and tablets have grown exponentially in popularity since 2009 when android only had 4% of the market. Since 2014, it has become the dominant player with over 84% market share when comparing the main six competitors on the market. This is at the time when smart phone penetration is reaching new levels with 70% of population predicted to have access to a mobile device by 2017. This is one of the reasons that mobile application development is increasingly taught at universities on courses such as our Business Information Technology course.
