Q: upgraded iphone5C to ios 9.0.2 - now do not have keyboard to add or edit contacts-help!

Close all open apps by double-tapping the home button, then swiping up the app window until it flies off the screen.

Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

Glad to hear that You can do this any time something is not working right or things are going wonky; it's like rebooting your computer.
