Dual Capture Mode
The Galaxy Note 8 has two cameras on the back. One takes great photos, while the other offers a 2x optical zoom and is a telephoto lens. As an added benefit, the Note 8 is the first dual camera phone where both rear cameras have optical image stabilization. This means you'll get great photos even when you zoom in.
One of the best things the camera can do though is Dual Capture Mode. This takes two photos at the same time, and it's really easy to do. Fire up the camera and swipe to the left to access the different modes. Then, select dual capture and take some cool photos.
Dual Capture mode takes both a regular and a zoomed in photo at the same time. One click, two photos. Yes, it's sort of a novelty feature, but I've had countless moments where I take a photo and crop it later. This way, you'll probably already have the perfect shot.
The Note 8 also has "live focus" so you can change the focus point on a photo before OR after you take it. That's neat too.
