If you have elected to lock your camera with a pin, passcode, or pattern, you will notice a lock icon appear over the gallery when your camera is locked.
If you want, you can remove the passcode on your camera so you don't need to unlock it every time you want to see your photos.
To do so:
1. Swipe down from the top of the screen 3 times to reveal the Control center.
2. Tap the gear icon to open the camera's settings menu. You will need to enter your passcode at this step.
3. Tap Security.
4. Tap Screen lock and enter your current passcode again.
6. Tap "None" then "Yes, Remove."
Tip: If you have forgotten your pin, passcode, or pattern, you can reset your device.
