The Sony Ericsson K550 is a mid range mobile phone. Announced on February 6, 2007, it was the successor of the K510 model sensor with two-LED photolight and an active lens cover for the camera lens protection and easy camera activation when taking pictures from the phone. The phone has a variant in the form of K550im which was the first i-mode enabled phone bearing the Cyber-shot logo trying to build into the success of the Sony Ericsson K610im model. The phone was one of the first Sony Ericsson models in which the user can find the Fast-Port system connector at the left side instead on the typical bottom part.
