The Taiwanese company Tryi Yeh that designed the Go concept cell phone. The phone really looks incredible with flexible OLED touch display. Plus the phone has a sliding body, featuring mode keys and a camera. You can use it as an antenna for watching TV. One more very interesting feature of the phone, though probably made only for the sake of a good design, is the color-changing back.
If the phone is red and flashing than the gadget will soon shut down & if it's green, then the phone is 100% and if it's white then you know that someone's calling.
