I happen to use this quite a bit. Most people may not use this feature but I thought I'd post this anyway.
I noticed that this function did not work near as well on the S8+ vs. my Note 3. It wasn't as polished and didn't offer the same nice features. It honestly wass a hassle to use. I looked at the settings when I first got the phone but saw nothing that would change it. So I looked again this morning. General Management, Language and Input, Virtual Keyboard, Manage Keyboards. Then de-select Samsung Voice Input. When I firest looked at these settings, I just looked at the setting right above it called Google Voice Typing which was selected (keep that one selected). De-selecting the Samsung Voice Input did the trick.
Anyway, much better now!
