Antwort auf „Screen only works when pressing behind top left corner”I have the same issue with my iphone 5c but it's a little more complicated, the image "dies" if I don't press the top right corner, this error ocurred after I replace the screen, which is ironic, because I was fixing and issue and found another! I read a few blogs and saw a couple of videos saying that may be dust in the connectors, but nothing helps me, BTW, I tried to put my screen in another phone, and it died too... was my screen broken, ok so a new screen should work, right? WRONG! no matter how many screens I test on my phone all of them keep dying the image if I don't keep pressing, so you're probably thinking that my motherboard is broken, but nothing explains why other phones when in contact with my screen die too... a "screen virus?" I don't know, the only thing I know is that I can't find a diagonosis except to buy a new one since we're talking of a 2013 iphone 5c running in 2018, there's no warranty anymore!
