Well, a patent application that has gone public thanks to the Korean Intellectual Property Office shows that Samsung has toyed with this idea since April – last year.

It remains to be seen whether this will make it to future Samsung devices, but at least we do know that they are in the right direction if the need ever arises. [PDF File]
