This happened after I replaced my battery and I follow through all the instructions and it was successful.However after put all the thing back,and turn on my iphone I spotted this greyish dim spot surrounding my iphone 7 plus display.I am curios if the opening suction cup put much pressure on the display when I try to open the screen and cause tension to the backlit lcd? Has anyone experienced the same problem like this?
Aftermarket batteries will often do this, even occasionally causing the screen to flicker around the edges (especially when the phone is low on battery). If it doesn’t get any worse I would say it’s just due to the battery and shouldn’t really be any cause for concern. Hope this helps!
