Why can I not remove my screws inside of my XR phone? I ordered a kit from Ifixit and it came with 3 screwdrivers and none of them work.

You should be using the tri point screwdriver. If it’s not in the kit you can purchase one by itself on ifixit. Update (05/28/2020) It sounds like you have the wrong screwdriver. I would buy a set of bits with a driver. That way you can test them to see which one works. You be honest I have never looked at the size of the bits or screwdrivers I just look at the tip and know it to big or small.
