On an iPhone, "Show Previews" refers to a notification setting that controls how much information from incoming notifications is displayed on your screen. This setting can be adjusted for various apps and applies to notifications you receive on the lock screen, home screen, and in the Notification Center.
There are three main options for "Show Previews":
Always: When this option is selected, notifications will display the full content in the notification banner, lock screen, and Notification Center. This means that you’ll see the complete message or alert, including text messages, emails, and other app notifications.
When Unlocked: With this option, notifications will only show a preview of their contents when your device is unlocked. When your iPhone is locked, you’ll see the app name and that you have a notification, but not the detailed content. This helps keep potentially sensitive information private while the phone is secured.
- Never: If you choose this option, no preview of the notification content will be shown at any time. You will see only the app name and an indication that there is a notification, but not the details of the message or alert.
You can change these settings by navigating to Settings > Notifications, selecting the app you want to modify, and adjusting the "Show Previews" setting according to your preference. This feature helps you control your privacy and the amount of information displayed on your device based on your security needs.
