Open the Camera from the Lock Screen
Granted, most of us probably already knew this trick, but Apple Support still wants to share it with the world.
You can access your camera without ever unlocking your iPhone, which is great if you want someone else to take pictures without having full access to your phone.
All you need to do is swipe to the left on your iPhone’s Lock Screen. Or you can also long-press the camera icon in the bottom right corner of the Lock Screen, and both options will take you to the Camera app.
