Probably the rock in a shoe trick as well if that’s actually a thing.

Not as bad as you’d think, better than typical phone repair at least (not that I have a ton of experience with that).

It’s been a while but if I remember correctly you have to unsnap the grill that’s wrapped most of the way around the speaker using a spudger, and then the rest is pretty easy and I think mostly screws.

Same with my flip 3 or 4, I replaced the battery but it’s been good!
