Johan Loekito has found an ingenious way not to lose your phone ever again. He called it Samsung Proxima, a concept that includes a cellphone with a wristband acting like a dock.
The concept phone has also a proximity sensor on board that is making the wristband to emit a tone or vibrate if the phone gets too far from it, which helps the owner find his phone with one button press. At the same time, Samsung Proxima is able to detect other users with the same phone in your area and lets you contact them. (via Beautifullife.info)
