Your iPhone’s text message alerts can display previews of messages that you receive. One of the options is for these previews to display on the lock screen, allowing you to see both the name of the contact sending a message, as well as a brief snippet of the message that they have sent. In the case of short messages this can allow you to read the whole message without even touching the screen.
Unfortunately this also means that anyone within view of your iPhone screen (or maybe even your iPad if you’ve set up text message forwarding) can see this, too. If you find that people are sending you sensitive or private information, you might prefer that the contents of their messages not display at all in these alert previews. Our guide below will show you where to find and change the setting that controls this.
How to Turn Off Text Message Previews on the Lock Screen of an iPhone 7
The steps in this article were performed on an iPhone 7 Plus in iOS 10.3.3. The result of completing these steps will be text message alerts that appear on your lock screen, but only show the name or phone number of the contact. You will no longer see a snippet, or preview, of the text message that they sent.
Step 1: Open the Settings menu.
Step 2: Select the Notifications option.
Step 3: Scroll down and choose the Messages item.
Step 4: Scroll to the bottom of this menu and tap on the Previews option.
Step 5: Select the Off option to prevent showing previews in any alerts or banners, or choose the When Unlocked option to see previews only when the device screen is unlocked.
If you would like to stop showing any indication of a new text message on your lock screen, then you can also consider turning off the lock screen alerts as well. This will make it so that you need to have the phone unlocked to be able to both see that new messages have been received, as well as read the contents of those messages.
