ETNews says that the Korean electronics giant is testing the ‘diamond metal surface treatment.’ However, the company won’t be coating real diamonds to make the device sturdy because that would be an extremely costly affair. Instead, the Galaxy S5 would have a ‘diamond-like’ material coated on its metal case. Though it may trigger a few changes in the Galaxy S5’s external design, it will make the device resistant to scratches and deformation.
