This is the official Sony Ericsson Xperia X10a User Guide in English provided from the manufacturer. If you are looking for detailed technical specifications, please see our Specs page.
The Sony Ericsson Xperia X10 is the manufacturer's first Android phone. It is rather high-end, equipped with a 1GHz Snapdagon processor, 4-inch TFT screen with a resolution of 480x854 pixels and an 8.1-megapixel camera with autofocus. However, its software features are just as impressing. What it adds to the Android universe is a personalized interface, called UX (from User eXperience). Basically, UX combines various entertainment and social media features.
