Android OS is an open source operating system developed by Google that runs on phones and tablets. It is based on the Java programming language and Linux kernel, allowing anyone to develop applications for it. While openness allows for greater innovation, it also presents security risks if apps are not properly vetted. Android has grown to be the dominant mobile OS worldwide.
