Keeping touchscreens clean

Considering my profession, cellphones has the major priority among products which I analyse.

It is a very common concern to keep large and touchscreen phones clean. Each time we use them, they get dirty via our make-up or skin.

We may solve this problem with positioning extra mic and speakers backside. This may be maintained with locating a sensor to the backside or this option may be selected while answering from the menu, as seen on the figure, and the screen light may turn off when backspeaker and backmic are on.

You may ask why I don't secure this idea by patent?
