Have you...

1. Restarted (turned off and back on) the phone?
2. Checked the phone for viruses?
3. Checked the phone for malware? (the are different)
4. Uninstalled any newly installed apps or app updates that were installed/updated just before the problem started? (be sure to restart the phone after the uninstallation).
