UIQ, short for User Interface Quartz, is a user interface for the Symbian OS developed by the Swedish firm UIQ Technology. It is most commonly used on Sony Ericsson's P series of smartphones, such as the P990. Late in 2006 Sony Ericsson announced its intentions to acquire UIQ Technology, and stated that it would be run as a separate division inside of Sony Ericsson and that the UIQ interface would still be available for licensing by other companies on equal terms.
