So, I started to work on replacing my phones battery, and I got all of the screws out except for one, which decided to strip on me, I’ve already ordered the extractor set, and I’m wondering what kind of screw to replace it with, or if I can go without one screw.

if all the other screws hold the component in place decently then you should be fine like i there were 4 screws and you extracted 3 , you would be “ok” unless is less than 3, then i suggest you try to find the screws
