Hi, I installed the the replacement battery successfully however I realised that the cover which covers the connector for the battery is pressing against the phone screen. This is causing a grey mark around the screen where the pressure is. I’ve went to try to take the screws back out to fix the issue but one seems to be stuck. I’ve tried the elastic band method and pulling the suction cup up while screwing however, neither are working. Thank you!

At this point you can either use the ifixit screw extractor if you can get a grip on the screw or you may have to drill it out.
