回答“White lines only on top of iPhone 6 screen”I got those too after doing a battery, WiFi adapter, and flex cable swap. I had a heck of a time getting the ribbon cables seated. I noticed over the next few hours, the bars started to disappear, because I had to drain the battery to less 10%—leaving the screen on at full brightness. The next day I didn’t see any bars at all, so I’m not sure what that was about, but it seems to be OK now. Out of curiosity, did yours go away too, or did you have to replace the screen/cables?
