Autosuggestions are nice to have but there is no autocorrection that really works well in my experience regardless of OS.

I turn off automatic autocorrect except for "I". I can use it manually when I need it (jot often).

this was my experience. the autocorrect for heliboard is beyond atrocious and renders the keyboard unusable.

i ended up just using gboard on gos because every other one i tried fell short.

hopefully the stock gos one can be reworked into an actually decent keyboard.
