Symbian OS

Symbian OS is an operating system with associated libraries, user interface frameworks and reference implementations of common tools, produced by Symbian.

There are multiple user interface flavours that use the Symbian OS, such as UIQ and Nokia's Series 60. The adaptability of the user interface enables the use of Symbian OS on various form-factors of hand-held devices: clam-shell or tablet, keyboard and/or pen, PDA or mobile phone, and others.

The current Symbian OS is derived from the EPOC32 operating system, which was used on Psion Series 5 PDAs and originally developed by Psion Software. The Symbian OS has since gone though several versions.
