Why Does the Alarm Sound Keep Occurring in 'Vibrate' Mode Even During Calls on the Galaxy Z Flip6 and Galaxy Z Fold6?

In the One UI 6.1.1 SW version, the alarm/timer notification concept has been improved so as not to miss the alarm/timer information. When the alarm/timer notification comes up while making calls, the beep sound will occur continuously until dismissal.

• You can terminate it by tapping ‘Dismiss’ on the notification pop-up.
