There may be some virus attack on your device .
You need to have good antivirus such as Quick Heal or Avast antivirus and scan your whole device.
Also uninstall unsecured or unknown application from your device for this-

1-Go to settings from main menu.
2-And then select application option.
3-And then go to manage application option.
4-And select your unknown application from the list the application and uninstall it.

If still facing same issue then factory reset your device for this-

2-And then select privacy settings.
3-And factory reset your device.
