If your iPhone pulsates but there is no notificationthen what you do is go to “Settings”. Scroll down and going to see notifications. Go to “Show previews”. Make sure that it is not never. It’s either “when unlocked” or “Always ‘. So, the other thing which you have to takecare is if there is a particular app which does not show notification then you have togo to the app. For instance if Facebook does not show notification, I will go to “Facebook” and make sure that this “Allow notifications” is turned on andall of the buttons here they are turned on.
