Did you know your iPhone could do this?

Respond to texts without unlocking the phone.  When you get a notification, swipe left on the message and a blue “Reply” button appears.  Just tap it and text away! Take a photo with the volume button.  For that ultimate, one-handed selfie, open the camera app and press the “+” button for volume on the side of your phone.  Have Siri read your texts out loud.  This is a great tool for when your hands aren’t free or you’re on the road. Press the home button and hold it.  When the beep sounds, tell Siri, “Read my texts.” When done reading, she’ll ask you what to do with the messages.  You can have her reply or read them again.
