S7 edge acting as it is remotely controlled

[Horia Cretu]

After last os update my s7 edge started to behave funny. At some point when i tuch screen to make a call although i do it in the upper part let's say the phone reacts on the down side of screen. It suddenly starts to act super funny like someone else is controlling it or like buttons on screen of the ones on phone have been remapped. It is that sensation when you have 2 mouse connected to your pc and when you want to use one, the other mose controlled by someone else is moved or clicked suck that you input will be on a diffrent area or icon.
When trying to restart is almost impossible an i have to be real fast as it feels like someone is pushing the back button. I am unable to restart but to power off. After that all becomes normal but it is the second time this happened this week. Any clues? Never had this problem on my previous LG G3.
