On the iPhone 14, the notification panel can be accessed by swiping down from the top of the screen. This will reveal any new notifications, such as text/message alerts, missed calls, and other app notifications.
If you have multiple pages of notifications, you can swipe up or down to browse through them. To clear notifications, swipe left on a particular notification to reveal the "Clear" option or tap the "X" icon on the top right corner to clear all notifications at once.
Alternatively, you can also access the notification panel from the lock screen by swiping down from the top of the screen. However, depending on your security settings, some notifications may not be visible until you unlock your device.
It's worth noting that in iOS 16, you can also customize the notifications that appear in the notification panel by navigating to Settings > Notification Center and selecting the apps and types of notifications you want to receive.
