Try these steps please.
This sounds like a glitch in the software and the iPhone needs to reboot, lets try and force a reboot > Hold the home button and the power button down for about 30 seconds or until the Apple logo appears on the screen, then release both buttons.
Let me know if this does not work and we can try another solution.
