Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

PSA: Group FaceTime's Video Chat Not Available on Older iOS Devices
Group FaceTime is designed to let iPhone, iPad, and Mac users conduct video and audio chats with up to 32 participants at one time, with new camera effect features like filters, stickers, Animoji, and Memoji included.
Unfortunately, Group FaceTime is limited on older Apple devices. On the iPhone 5s, iPhone 6, and iPhone 6 Plus, it is available in an audio-only capacity with no video. In its recently released iOS 12.1 user guide, Apple says that Group FaceTime video is not compatible with these devices.
"Note: iPhone 5s, iPhone 6, and iPhone 6 Plus support only audio Group FaceTime calls. Group FaceTime may not be available in all regions."Group FaceTime is also limited to audio-only on the iPad mini 2, iPad mini 3, iPad Air, and iPod touch.
According to Apple's official Group FaceTime support document, Group FaceTime with full video is limited to the iPhone 6s or later, iPad Pro or later, iPad Air 2, or iPad mini 4, and iOS 12.1 is, of course, required for the feature to work.
Group FaceTime calls can be initiated via the FaceTime app or through a group conversation within the Messages app. When you're on a Group FaceTime call, the interface is organized into tiles, with the tile of the person speaking at the time getting larger so you can focus on each person.
Like regular FaceTime calls in iOS 12, Group FaceTime calls support a range of camera effects so you can use stickers, Animoji, Memoji, and filters during your calls.
Group FaceTime supports ringless notifications to let people join calls without disrupting conversations already in progress, and there are built-in tools for seamlessly adding or removing people from your chat.
