Phone with dim backlight with a glitchy toughscren
Ok so I have a white iPhone 6 passed down through the family. Before I received it, it had a cracked screen so the screen got replaced. However when I got it, the screen had blue/white bars going down on the right side of the screen and would get more noticeable depending on I believe the operating temperature of the phone. In addition sometimes, the touch screen would freak out and open up random apps. So I got the essential electronic repair kit from ifixit in order to try and fix the issue. I first tried to see if one of the connectors wasn't fully plugged in which wasn't the case. Then I and somebody else tried using rubbing alcohol I believe, on a piece of cloth to clean up any potential dust on the connectors. That ended up fixing the white/blue bar issue. However, the glitchy touch screen remained and the screen's backlight malfunctioned and currently can only deliver a minimal amount of backlight(Like 1/3 brightness at max). What I want to do now is buy another replacement screen to see if that will fix all the problems. However I am not sure whether the problem is with the screen connectors or the ports on the main body?
Is this a good question?
