Android is an open-source operating system developed by Google and the Open Handset Alliance. It allows developers to write managed code in Java and includes features like widgets, Bluetooth, WiFi support, and a wide range of media formats. While being open-source offers customization and cheap development, it also means the platform is more vulnerable to exploits and malware compared to closed systems.

functionality through standard API calls.
 Android phones can run many applications, it means you
can browse while listened to the song.
 Can install a modified ROM.
 Widget in home screen is awesome.

exploits
 Platform doesn’t run on an encrypted file system & has
vulnerable log-in.
