click Done.

2. Hide photo
Another useful feature of the iPhone is the ability to hide photos. It will help if, for example, you want to hide some of your photos from colleagues or friends to whom you show vacation photos on your phone.

3. Shooting video and photos at the same time
There are situations when you want to shoot a video and take a photo at the same time. On the iPhone, you can do both at the same time. For this: Start recording video in the Camera app. Next to the shutter button, you will see a round icon (in earlier iPhones, the camera). Click on this icon;

look for the received videos and photos in the Photos app.
Important: The resolution of pictures taken during video will be slightly lower than in Photo mode.
