The three phones – the Arc, Neo and Pro – all run the 2.3 version of Android, called Gingerbread. Sony Ericsson president Bert Nordberg said the companies want to be the leader in Android devices.

The Xperia Arc, which features a 4.2-inch screen and the Mobile Bravia display and graphics engine, will go on sale in March, said Cathy Davies, director of global marketing communications.

The company's Xperia Neo has an 8-megapixel camera, can record HD video and has an HDMI port. Users can browse through the device’s interface using a TV remote control, said Tony McNulty, product director. Other features include the ability to create folders for sorting applications and a pinch function that allows a user to see all of their widgets in one view.

Sony Ericsson is pushing the Xperia Pro as a phone for business users. Its e-mail interface allows users to see a preview of the message in the left-hand side. The Pro also has a slide-out QWERTY keyboard.
