What happened to him
So, the first two tests did not give us anything new: the display, like any modern smartphones, is scratched by objects with a hardness of 6 on the Mohs scale, and the pixels burn out over an open fire, but are quickly restored.
But the back panel pleased: like the iPhone 11 Pro Max, it is matte, but a trifle, keys and other objects that can lie with a smartphone in a pocket or bag does not leave marks on the surface.
However, the OnePlus 7T has problems with durability: as soon as Zack tried to bend it, a big crack appeared on the back panel. With new attempts, it only grew, although the smartphone itself still worked.
Perhaps the matter is in the design of the main camera: she received three sensors, which are located in the circular module in the middle. In any case, you need to be careful with your smartphone.
