At the end of September, OnePlus introduced an improved version of the flagship OnePlus 7 - OnePlus 7T. Zach Nielson, author
What happened to him
So, the first two tests did not give us anything new:The display, like any modern smartphone, is scratched by objects with a hardness of 6 on the Mohs scale, and the pixels burn out over an open fire, but quickly recover.
But the back panel pleased me:like the iPhone 11 Pro Max, it is matte, but small change, keys and other items that may be placed with the smartphone in a pocket or bag do not leave marks on the surface.
However, the OnePlus 7T has problems with durability: as soon as Zach tried to bend it, a large 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: it received three sensors, which are located in a round module in the middle. In any case, you need to be careful with your smartphone.
