Without knowing the root cause of your issue my advice would be to restore it to new by connecting your iPhone to your computer and restoring it thru iTunes
Another option might be to take your device to the Apple Store and have them run a diagnostic on it and see if there are any hardware issues. Try Kataran's suggestion first, and if that does not work then contact Apple....
