The Snapchat Camera icon next to a Snap means that the Snap is part of a Story that is being shared on Snapchat.
Stories on Snapchat are collections of Snaps that are shared with a user’s friends or followers on the app.
The Snapchat Camera icon indicates that the Snap is part of a Story and can be viewed by the user’s friends or followers.
If you see the Snapchat Camera icon next to a Snap, you can tap on it to view the Story and see all of the Snaps that are part of it.
You can also swipe left or right to navigate between the different Snaps in the Story.
If you want to share your own Snaps as part of a Story, you can take a photo or video using the Snapchat app and then tap on the Snapchat Camera icon in the bottom left corner of the screen to add it to your Story.
