Mi2s deffect screen

Описание: In this video I show a defect ordered my screen to xiaomi mi2s.
First, the program AliExpress, when previewing the directory itself is press the "Search" located at the top of the screen.
After, I go into the application to communicate. When typing on the keyboard at the bottom, spontaneously pressing the top of the screen, call up the menu.
Then I open the drawing program. I have not had time to do press, and top itself appeared point. Further, by drawing as having random dots and lines.
Then I turn on the option in the settings Xiaomi "show press" and "showing gesture" (trace).
Unfortunately, the video is difficult to see the trace and display keystrokes. But clearly it is seen that the drawing application draws the phone itself, without my intervention. Hand removed from the phone.
Then I turn off the phone and deal. Showing sent me a screen and pick the phone back.
After switching on again I spend the same tests on the application AliExpress and paint program. Deffekt remains.
