misspelling

Recently I often post my diary here from my iPad, and very often find odd misspelling in them. Sometimes it's just mistake of my typing but most of them are because of the iPad itself, it often automatically rewrite my lines. I understand it's supposed to correct my misspelling but often, very often it changed them into totally different words. And naturally I don't notice them until I reread my post next time! This is so irritating.  Or, is this because of LJ not because of iPad? At least I have not noticed the same phenomenon when I post from my desktop computer.
