Iphone SE left side screen problem/BUG

I've been having a problem with the screen on my iPhone SE for a few days now

the left part of the screen starts to go crazy (look at,, straight" line on the screen) To "fix" this, I have to lock and unlock the screen, the chance of this happening after unlocking the screen is about 40%. Does anyone have a solution?

(Screen show how screen behave when i write straight line)

Of course when i lock and unlock it will be fixed like nothing happened.

I think this happened after the recent IOS updates. In the picture, we can see straight lines being drawn with a finger, 1-2 cm of the screen on the left side show how its gonna crazy

the phone has not been dropped, I have never had any problems with it.
