I don't even know how to describe it or what could possibly be causing it. But TL;DR: For some reason, seemingly at random, when I type a word, it'll either duplicate the word before it (image 1), or just change to a completely different word or even a single letter (image 2). I reported this to Samsung themselves, hoping it would be fixed in an update (it wasn't). This would be less annoying if I didn't write and use text messaging (via Discord) for collaborations regularly, but it's getting to the point where I'm thinking about just pulling out the potato laptop. At least it doesn't weirdly autocorrect my words.
I've tried resetting the keyboard dictionary and things in that vein (nothing), and I'd disable autocorrect, but I'm a messy typer. It'd be more of an inconvenience than anything, and if that's the only solution right now, so be it. But I literally cannot fathom why this is happening.
(Image 1: Duplicate word.)
(Image 2: The entire word "not" autocorrected to "j". Okay.)
