iPhone 6s weird backlight bleed
Can i have some feedback from iPhone 6s/Plus owners?
Recently i had an issue with my, then, brand new iPhone 6s.
It had a really bad backlight bleed, so i got an replacement. This one also has a slight bleed, but it's barely visible, just a tiny spot on the left border, that can only be seen in specific conditions (max brightness, dark room, black image).
Anyway, what i find weird is that when i'm pressing the screen, in above mentioned conditions, the light kind a shifts and the slight bleed that was already there becomes more visible for a few seconds and then it goes back to a previous state, also the additional bleed, that wasn't there, appears for a few seconds and then disapears completely. I've seen the same behaviour from my previous iPhone 6s, the one i got replaced.
Is that kind of screen behaviour normal?
Thanks.
iPhone 6s, iOS 10.3.2, Silver
