Black sreen appears on the iPhone 7 plus with an incoming call

On the iPhone 7 and 7 Plus appears black screen. For example, with an incoming call, the screen simply does not light up (only the vibration and the sound of the bell), only responds to the power button. You press the Home button at least a hundred times, the screen does not light up, and the vibrating output then snaps and that's it.

It happens periodically several times a day, which does not reveal any sequence leading to this. Honestly, I'm sick of it already, I do not have to endure this disgrace, I want to pester the wall of the iPhone, it infuriates me, I'm ready to sell both.
