I have the same issue. I replaced the screen yesterday and opened the iphone 4 again today, because I installed the wrong home button (im new into business...). well, yesterday everything was fine and when I put the phone back together the screen started to flicker. I have one spare screen with a damaged digitizer cable and with this one, there is no flickering. does anyone know why? is my new screen broken?
