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.

iOS 13.3 Beta Includes Screen Time Communication Limits
With Communication Limits, parents can control who their children are able to contact. Communication Limits apply to the Phone, FaceTime, and Messages apps, along with iCloud contacts.
There are settings to control communication during Screen Time, with options to allow just contacts or everyone to be contacted. There's also a toggle that either allows or disallows users to be added to a group chat when a contact or family member is in the group.
There's also a separate setting for communication limits during downtime, which is also able to be set to everyone or just specific contacts.
Finally, there's a toggle for allowing or disallowing contact editing, which can change some of the contact settings.
Regardless of Communication Limits settings, calls to emergency numbers are always allowed and will turn off communication limits for 24 hours when placed.
With the Communication Limits feature, parents will be able to better control who their children are contacting during different periods of the day, cutting off access to friends during school, for example.
There are other smaller tweaks in iOS 13.3, including an option to disable Memoji and Animoji stickers from showing up on the emoji keyboard and a change to the Apple Watch app that shifts the Digital Crown on the icon from black to gray.
