I do NOT want autocorrect at all! It has been suggested that I just turn it off. Guess what happens? As soon as the phone does an update (like every other day) autocorrect is turned back on!
All keyboards have that option (at least the ones I know of). However, it's up to the app dev whether or not that option 'sticks' after an update. I've tried Swiftkey and the option sticks, so you might wanna give that a go. GBoard also has the option to turn it off, and while I haven't tried it, that's also a popular option.
