The iPhone X was tested for its durability in real-life situations such as being dropped from a pocket onto a tar road, being sat on or having excess pressure applied to the screen.
Youtuber JerryRigEverything conducted a scratch test on the screen of the iPhone X and found that not even a razor blade damaged the display. A bend test was also conducted in case of scenarios where one sits on their phone or pressure is applied to it at an angle. EverythingApplePro conducted a drop test from head height onto the back of the phone and found that it did not sustain any scratches or shatters. A second drop test was done, also from head height, this time face first.
