Brightness autochanges from screen content

[AC Question]

Hi! Annoying feature, first i thought it's a broken contact between the screen and the device. But don't. Brightness changes when screen content changes dark or majorly bright. How to disable this ***** disturbing peace of?

Lenovo Phab Plus, A. 5.0.2.
