The device, called Blue Earth, was unveiled at the Mobile World Congress technology event in Barcelona, and Samsung said it underlined the Korean company’s commitment to environmental stability.

The phone is designed to resemble the shape of a shiny pebble, and uses a small solar panel to provide power.

“This phone demonstrates our small but meaningful commitments for the future and our environment,” said JK Shin, an executive vice president at Samsung.

Blue Earth is made from recycled plastic and features a special “Eco Mode” that users can access with a single click to wring the maximum energy use from the device.

A full solar charge of around 10 to 14 hours will provide enough power for around four hours of talk time. The handset can still be charged normally using a conventional plug, with the solar panels used to top up the battery during use.

It also has a built-in pedometer to help users to measure how much smaller their carbon footprint is when walking rather than driving.

Blue Earth goes on sale in the UK later this year and Samsung did not give any details about price or network partners. However, sources hinted that the handset was likely to be priced at the upper end of the market.
