I am sorry to hear that you are having this issue. This is usually caused by a glitch in the firmware and can be resolved by a forced reboot, then your iPhone will work normally again.press the home button and the power button at the same time for about 40 seconds or until the apple logo appears then release.
Let me know if this does not work and we can try another solution.
