iPhone 6 Plus iOS 10.0.1 Been having this issue for something even when I was on still on iOS 9. When I type words like top, it will automatically capitalise the entire word to TOP. Also when typing words like iPhone, usually it will auto capitalise the P, but it doesn't do so. Please take a look at the video in this link https://vid.me/ylj5 for a better understanding. I have previously done a restore on my phone before via iTunes but still having the same issue. Tried resetting the Keyboard Dictionary but still same issue. I didn't store all of those words in my Keyboard Text Replacement also.
