Screen is very blurry when scrolling up and down
So I had a broken iPhone 6 so I replaced the screen like I had done many times. The phone was working properly but it was very blurry when I was scrolling from side to side or up and down. I thought maybe it was just a bad LCD display that I had bought so I ordered a new LCD display. I swapped them out and still had the same problem. I had an extra iPhone 6 laying around that had no battery and no screen, so I swapped all of the components to this phone thinking that maybe there was something internally that was causing the display to be so blurry on the other phone.
When I went to turn on the phone I had the same exact problem. So now I'm kind of stumped. Would love to get some advice from someone that knows more than me about these phones.
Is this a good question?
