How did you make that happen? I use swipe keyboard in iPhone. I turned off all "autocorrect" features they offer. Still their random generator keeps replacing perfectly fine words _and the words before them_ with random crap that makes no sense. Heck, I even turned off all features, and still it happens. So I switched to another keyboard from appstore. I would switch to another OS, but I find the others even worse in some respects I care for deeply.
