It's a bit drastic, but you can try performing a hard reset on your phone.
''Be aware that a hard reset will erase all your downloaded apps and user data. It will restore your phone to a factory default condition. It will be like when you first bought it.''
Before performing a hard reset:
1.Perform a backup of your data. Unfortunately using the phone's backup and restore feature doesn't help in this instance in that if you save your data/apps using the phone's backup feature when you restore your phone using the restore feature (using the backup that you made) you will just be re-introducing the problem back into your phone. Instead just copy your data (e.g. photos etc.) onto a PC. You will have to reinstall all your downloaded apps again
2. Ensure that the battery is fully charged.
3. Do not leave the charger connected when performing a hard reset.
4. Remove the external SD Card (if any installed).
