I don't know why it got the impression that "them" isn't a real word sometimes. It's been way worse at predicting what the words I actually want to say are lately, too. The suggestions are often words I rarely (if ever) use, instead of the words I use frequently. Usually it's the slightly less bad, but still annoying, guessing the right word with the wrong suffix. Like if I want to say "impressive", I have to type out all the way to "impress" to get it to suggest "impressive" and not just "impressed" (which I only need to type "impr" to get). Sometimes it never offers me the right suffix at all, and I have to type out the whole word myself.
It also takes pieces of links that I copy and paste once, and put it in its dictionary forever. (Also little note: it just """corrected""" "its" to "it's" in that last sentence. "put it in it is" makes perfect sense, thank you). But I can never get rid of built in words from its dictionary. Something to note is that that means capitalizations of certain words, and not just spelling. I never spell "god" with a capital G (unless it's at the beginning of a sentence), but I can't convince my phone of that. I am not a christian, and I do not refer to their deity that way >:c
I really want to install a different keyboard on my phone, but I wouldn't even know where to begin to look for that. All I want is a software keyboard that isn't made by a large company, and isn't too jank, but I don't think those exist. Ok actually I want a physical slide out keyboard for my phone but they don't make those anymore >:c
