I swear the android autocorrect got so much worse at some point. Somewhere between 5 and 15 years ago. I used to be able to type vaguely coherent sentences and all of the typos would magically become the words I meant, even if they didn't look right. Now I frequently type completely correct sentences and the correctly spelled words get changed into other words that make no sense in context.
And i used to be able to backspace the wrong word and fix it and it would learn thats what I meant. Now if I try that, it'll frequently keep trying to edit to the word I didn't mean unless I press the little checkmark in the autocorrect panel. Just annoying UX.
