Not sure where to post it as it is about screws and we have a separate topic on the battery thing, and it is somehow also connected to handling water damage also mentioned there by @urs_lesse
but it is also more general cause it is about screws’ types and screwdrivers.
When purchasing FP5 I was thorough/cautious/careful enough to purchase an ifixit screwdriver with it. I felt like a rookie in a world of repairable phones and did not trust anything I might already have back at home to be fine enough for my new FP5. I reckon I would do the same thing when purchasing a FP6 - I would have bought a Ifixit screwdriver offered in the webshop and learnt along the way something about Torx screws. I can also accept that a screwdriver is not offered for free.
But there is another one offered for free - the smaller yellow one, that you are to get when you buy some accessories (given you need to screw them in).
The tutorial clips for spare parts for FP6 include a big Ifixit screwdriver, the tutorial clips for accessories include a small yellow one.
Are they interchangeable? Which screws are bigger? Why do we have two different types?
PS. Just had a crazy thought that it would be nice to be able to somehow attach a screwdriver to a case. Like it would be awful to run into issues while on holidays/abroad/in wilderness and having no screwdriver to solve it.
