    Probably during the OTA update to denim you got a glitch.
    Did you already do a soft reset.
    Hold down, power and volume down, simultaneously till the phone vibrates.

    If this does not help you should do a factory reset but be aware that this erases all the data on your phone so first be sure that you make an backup.

    If you still have questions please register and reply on this post.
