Google's upcoming Android 15 update, initially previewed to developers earlier this year, has introduced a new feature called "notification cooldown." This function is designed to gradually decrease the volume of notifications, when an app sends multiple consecutive alerts. However, it was noted that this feature did not stop the continuous vibration of the phone due to these alerts. In the latest Android 15 Beta 1.2 update, a new toggle has been discovered labeled "vibrate when unlocked."
