Just got my new screen in for the iPhone X, the repair itself went fine and the screen works great, however, when I try and finish the repair by putting the screen back into the frame it won’t fit! SIM card slot had been taken out already, it’s like there’s a border going around stopping it from going in properly

I see exactly what the issue is now. The screen has separated from the frame. Call up ifixit and submit a warranty claim. It’s an issue we see from time to time in the repair industry. I’ve seen it happen a few times with my screens as well.
