Step-by-step explanation:
How to Slide Down Notifications on an iPhone
To view notifications on your iPhone, you can simply slide down from the top of the screen. On an iPhone with Face ID, swipe down from the top-right corner of the screen. This gesture will open the Notification Center, where you can view all your notifications. If your iPhone has a Home button, you will instead swipe down from the top center of the screen.
Remember that the exact method might vary slightly depending on the iPhone model and the iOS version it is running. However, the basic gesture remains consistent across most iPhone models.
To close the Notification Center and return to your home screen, simply swipe up from the bottom of the screen or press the Home button if your iPhone has one.
