Sony Ericsson combines Sony quality with Ericsson's expertise and market knowledge in the mobile field. In addition to its former range of feature phones, the company is also known for the Xperia series of Android smartphones.
Sony Ericsson was quick to combine the expertise of both its parent companies with the launch of the W-series music phones, the first mobiles designed as much for music as for communication. These mobiles carried their heritage through the Walkman branding and the large W button that provided access to the media centre. Sony Ericsson Cyber-shot phones took inspiration from Sony's camera line, and included features such as auto-focus and a Xenon-based flash for night photography. They also produced the eco-friendly GreenHeart line.
