Glitch in iOS design

Question

I can't submit the answers to the final quiz bc when I hit 'check' button it just opened the keyboard. No way to hit button without opening key board.😕 actually no option to close the keyboard in a number of situations including the this comment submission form.

Answer 1

Just hit the back-button on your phone. Don't iPhones have 2 settings for the home-button? Pushing it down all the way (2 clicks) takes you home, while pushing it down half-way (1 click) acts as a back button, right?
