How do I get back to standard keyboard
I don't know how, but somehow I've changed the characters that show on the numeric keyboard. How do I get back to the standard one? To be specific, I've lost the "(" and ")" characters, which are critical because I use them in passwords. So if I can't find them, I can't enter my passwords!
How do I get back to the standard, preferably without having to do a total system reset?
This is an iPhone SE using iOS 10.
Thanks.
