For some context, in Zack’s previous videos on devices typically using Gorilla Glass 4, it usually takes a 5 or 6 hardness pick before scratches occur. But in the Note 7 video, non-removable marks are ...

This film discusses hardness testing methods in engineering, specifically focusing on the Brunell and Rockwell hardness tests. It explains how hardness is measured through indentation and penetration ...

At this point, we know all there is to know about the Galaxy Note 7 smartphone. We have spent hands on time with the device and recently published our review of the smartphone. If you want to know how ...
