Thank you ifixit! First attempt worked well. All back together and working. Very clear instructions and images. Took my time, no rush. I used the pointy end of a cable tie (flat) in lieu of the pointy end of a spudger in step 27 to lift the earphone speaker. Very helpful outline and instructions.

I do not know what the proximity sensor actually looks like. I would find it helpful if there was a picture (or indication on the picture) of its location.
