Fantastic instructions. Thank you. I had a challenge with the suction cup (see my comment for that bit of the instructions for workaround), but other than that the whole thing went smoothly. The final step of using the Google calibration software is essential.

I gave up with the suction cup. My screen was too cracked. Instead, after applying heat to loosen the glue, I used a very tiny flat head precision screwdriver to prise the screen open. Not recommended as it leaves a tiny scratch, but saves a lot of hassle. See also https://www.youtube.com/watch?v=vxdaaTd7....
