Although spam-warnings work even when the app is closed completely, the spam protection can not be updated. The app has to run in the background. If you rarely or never open the app, spam protection will quickly become obsolete. This can mean that you are no longer reliably warned from spam calls. New spam numbers are constantly added, so an always up-to-date spam protection is essential.
That’s why we send a notification (push notification) periodically to alert you to a possible update. When the notification is pressed, the app will open and the update will start.
It’s best not to close the Clever Dialer app completely, but keep it running in the background.
