There are a few methods you can use:
1. fail enough times and it progressively slows down
2. screen record or record on a phone
3. draw the 5 crystals on a piece of paper and draw a line in the order for each step. This is the one I would recommend because then you don't have to spend an eternity failing or juggling another device/recording
4. skip it, on 1.6 you can buy walnuts
5. Since you're on mobile, you can also just create a save at the start or the day there, then if it gets too late, exit and reload the save right there. There isn't a reason to spend multiple days not getting it.
