Make Text Messages Private on iPhone
When you receive a new iMessage or Text Message on your iPhone, it immediately notifies you with a New Message Alert, which appears in your device’s Notification Area and on the Lock Screen.
In the New Message Notification, iPhone shows a brief preview or selected content of the Message to give you an idea of the content of the incoming message.
While this feature is handy, it also gives people around you an excellent opportunity to guess your activities by looking at Message Previews on your iPhone.
You can either disable Message Previews on iPhone or disable them on the Lock Screen while allowing them in the Notification area, depending on your privacy needs.
