In the Settings menu of your phone, go to Apps, find Snapchat under the list, select Permissions, and turn on Camera permission. Visit Settings on your iPhone, choose Snapchat, and toggle the Camera access to ‘On’.
To allow Snapchat camera access in 2025 (or any time!), Go to your phone's settings. Find "Apps" or "Application Manager," then locate Snapchat. Tap "Permissions" and ensure the "Camera" permission is toggled on. If it's off, Snapchat can't use your camera!
