I just replaced my iphone 4 screen for having horizontal lines/flickering. It still sort of had it after I replaced the screen (I replaced a few days ago) but really was just fine and today I thought maybe the screen cables were loose because after my phone died and I re-charged it, I got a fully white screen. So I opened the phone up, unplugged battery, and re-sat the cables. Turned the iphone back on, now it has this obnoxious (pure white with burned keyboard showing) white flicker around the edges of the screen. I've done the obvious: I've tried turning off auto brightness/ adjusting brightness. I've tried turning off/on. I've tried restoring/updating. re-checked that I didn't leave any cables loose Any ideas? I've done this quite a few times and never had an issue.
