I have the hardest time with "its" I read it correctly but when I write it, 9/10 times I originally write "it's" -- it's possessive! and by it's I mean its. Jim's, Jerry's, June's, It's.
I get we don't say hi's and her's or your's -- but other than hi's they look fine with apostraphes too.

I am locked in such a war with my phone's autocorrect. I am positive that it has developed its own proto-intelligence approximately the level of a 6-year-old human or not particularly smart herding dog.
