Samsung's new Clover concept phone that features four different modules to suit changing technology trends.The four modules are vision, location, sound and sensor, and can be tweaked either by developers or users to suit new trends. For example, developers can integrate fitness applications to the sensor module, or add hardware to the device to improve the camera.The Samsung Clover is manufacturered using recycled materials, with a PLCD sensor to switch the casing from opaque to transparent in different situations (such as a low battery).
As a concept device, there's no word on when we can expect the phone to appear as a working model or even be released as a product on the market.
