Be sure to remove the blue protective film from the BACK of a replacement screen.
Completed the replacement of the screen on an iPhone X. First, I HATE y000 screws! I think this is Apple’s way of trying to dissuade users from attempting a repair no matter how adept they are at repairing electronic equipment. Pentalobe is fine, I can work with them. Second, big fail (IMHO) on no warning about removing the protective film on the BACK of the screen. It’s not obvious that the film needs to be removed. As this was the first time repairing an iPhone X I did not pick up on removing the film until I could not get the touch function to work. Had to disassemble the screen to remove the film once I realized it needed to come off. A caveat sticker on the packing material would be a nice touch. As the repair was a success I am pleased. The instructions were very good especially the link to the adhesive installation. Could use a note of caution when cleaning around the bottom ground contacts. The fingers appear to be foil and are easily damaged.
