I have two issues in Finnish with Android's (Gboard) autocorrect: inflection and language selection. In Finnish, words can have over a thousand inflected forms. Granted most of them are not used usually but every day I bump into a word that the autocorrect knows but when I add the inflection, it no longer recognises it. It tells me that it doesn't actually parse or "know" Finnish text, it just has a huge word list. The second issue is that it decides which language's suggestion to show based on the characters I've typed (since I have it set to both English and Finnish). Normally it shows suggestions from both languages but if I type a single ä, ö, or å, it never suggests an English word. This is unfortunate since I sometimes hit such a character by accident and I have to go back and retype the word from that point to get back the English suggestions.
