As the process continues to the bend test, we see the antenna line being a weak point that gives way to the bending. For some reason, this causes the vibration motor to malfunction. Another bend killed the display, even when the Gorilla Glass Victus remains intact.
Flipping the ASUS ROG Phone 5 to the back, another bend sees the side USB-C port serve as another weak point. This bend shatters the glass back, showing the discrepancy in durability between the front and back glass. While phone makers usually don’t disclose what sort of glass they use at the back, unlike with what covers the display, in this case it’s probably not the Gorilla Glass Victus, judging from the way it shatters.
Of course, no phone is expected to endure that kind of force under normal use scenarios. But as the ROG Phone 5 is a gaming phone, the chances of it happening are higher. After all, emotions do run high in certain situations while gaming.
