Horrible text prediction and auto correction in Hungarian

All of the Hungarian users who have iPhone are shocked how horrible the Hungarian text prediction and auto correction is! I've been using iPhone since 2016 and it's been a good choice to switch from Android, however I'm really dissatisfied about the poor quality of predictive text and auto correction, and the fact that it hasn't been improved one bit since I use iPhone. Hungarian is an agglutinative language, suffixes are added to the stem but the dictionary fails to remember these. It keeps correcting words and removing suffixes, however, it often remembers incorrect words I misspelled one time, yet it remembers the misspelled form! After a single use! This is extremely bothering as I constantly need to go back and delete parts of the text, change words. Oftentimes it corrects the whole word to another we barely use or to a proper noun even, which makes no sense. It doesn't recognise words we use frequently but offers words we barely or never text. Another option would be of course to turn off the auto correction and prediction, in which case it takes ages to type in words including accented or dotted characters, and frankly, I don't see why we can't have the option of a well-working auto correction system. I'm writing this on behalf of numerous Hungarian users as all the iPhone users in my country are extremely dissatisfied over this phenomenon and the lack of improvements. Can we expect a remedy in the near future? I certainly hope so, this is so bothering in everyday life, I'm considering buying an Android model for my daily texting (which is a lot)!!
