The BenQ-Siemens phone concepts are only conceptual designs. The first is a snake-like phone that can wrap on your arm (?) and has controls on the outside. The second is a phone with a rotating screen that flips out and can rotate. Luckily they are only a conceptual design, meaning there is a.0001-percent chance of actually being manufactured. The last phone is a bit more normalfull screen display/touchscreen and sliding control bar. It is only a concept phone.”]
