Android is an operating system or (OS) that can be found on a range
of devices today and is growing in popularity fast.

manufacturers is because it’s ‘open source’ software
and therefore essentially free for manufactures such
as Samsung to use.
This is unlike a ‘closed source’ operating system such as Apples IOS.
