Typing this on a fold4 would just like to chime in that after a year of ownership the inner screen did fail seemingly for no reason. I was able to get this fixed but I just want to stress they do have some problems.
Partner has gone through 3 flip4 in the same amount of time though that phone is garbage.
Went through warranty replacement for a TV and was simply asked to write "void" and a big X on the warranty sticker. Even had the option to give the almost perfectly fine TV away (I did to someone who greatly benefited from it)
