Android comes in many shapes and sizes and almost every vendor or smartphone manufacturer has its unique take on the operating system. What gives them the liberty to customize Android is the fact that Android is an open-source platform. This list goes beyond the Android variants designed by brands and also includes the multiple different strains developed by independent developers in the form ofcustom Android ROMs. And just like the numerous variations of Android, there is a variety of open source Android apps that are very purposeful although they might have not received the kind of attention they deserve.
