I can blindly type with an on screen keyboard, it’s not that hard. What’s wrong with your phone where taps aren’t registering? And poor text prediction would be the same on physical vs on screen KB. My old Pantrch Duo would frequently ignore physical key presses where it tactically clicked, but failed to actually bottom out enough to register. And I have that issue all the time with mechanical keyboards where the tactile bump happens before the key actually gets registered. Not an issue for typing, but for gaming I do it often.
