All functionalities of a badge are available while a background update is in progress.
If you make or receive a call, the background update is automatically paused so that it does not affect call quality. The following icon represents the background updater:
While background update is paused, the icon does not appear on the screen. When you finish the call, the background update process resumes and, the icon appears on screen again until the update is finished.
The duration of the update varies based on whether the badge is used to receive or make calls during the update process. If you pause the update several times to make or receive calls, the update process will take longer. However, since the background update does not prevent users from using the badge, the duration of the update is insignificant. You may not even notice that an update has occurred.
