I've had this same experience moving from a 13 Pro Max to a 16 Pro. I assumed it was the slightly smaller screen/keyboard wreaking havoc on my fat fingers but perhaps it's more detailed than that.
Sounds like you need to reset the dictionary. I have to do this every so often.
Settings > General > Transfer or Reset iPhone > Reset > Reset Keyboard Dictionary.
The iPhone learns overtime words you type e.g. names and places. I find after a period it just goes whacky and starts letting you just make up randomly words.
Yep.Gotta love the irony.
I personally have observed iOS/iPadOS autocorrecting words it shouldn’t, and not correcting the words it should (it suggests it with a red line underneath instead of just correcting it).
OK, only 2 days in, but I am pretty sure typing is much better.I am trying this. I have had issues with typing for a few years now, it just was not that accurate (same typing speed just more typos, or hitting the wrong letter).
I had this happen with a different phone, a Galaxy Note 9. First one I had typed fine. Lent it out and got it backed cracked screenI can't typ on iPhones above 12. Typing this on iMac, because on my 14 Pro it couldn't be done.
Don't know how to describe but typing on 14Pro is just ****ed. Can't typ a normal sentence without mistakes. Autocorrect is on but has to correct just everything.
but then, I used my moms phone (12) and everything went smooth and not a single problem at all. Used an iPhone 8 to test. 10 times better. Held the phone next to each other, there is more space between letters it looks.
You should take an old iPhone and type on it, it's just unbelievable. I cant be the only one. Wanted to switch to Samsung just because of this.....
