Yup, same here and I'm on Android. I'm in my late-twenties and have spent most of my life on mobile devices and keyboards like most people here. Over the last couple of years I've been getting frustrated to no end by the exact things you're talking about. I always have to retype words, basic things get auto-corrected to capitalized, proper noun versions that make no sense in context, etc. I'm starting to think that the older folks that dictate their text via microphone have the right idea.
