iOS9 how to change back to ALL CAPITAL keyboard?

After using Apple iPhone keyboard for close to 4 years, I'm quite proficient with typing on the keyboard, almost touch typing, while relying on autocorrect.

The new lowercase keyboard totally throws me off.

How can I get my iPhone with iOS9 to go back to default keyboard where all characters are capitalized?

Go to Settings > General > Accessibility > Keyboard and set the 'Show Lowercase Keys' to off.
