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.

Apple Seeds First Beta of iOS 12.4 to Developers
Registered developers can download the new iOS 12.4 beta from Apple's Developer Center or over-the-air once the proper configuration profile has been installed from the Developer Center.
As a 12.x update, the new software may include more significant features than the smaller 12.x.x updates. iOS 12.4 will mark the the fourth major update to iOS 12 after iOS 12.3, which introduced a redesigned TV app with Apple's new Channels feature for subscribing to and watching third-party subscription content right in the TV app.
We don't yet know what we can expect to see in iOS 12.4, but we'll update this post as soon as we download the software and discover what's new. It's likely that this beta includes some Apple Card-related features, as the Apple Card is set to launch in the summer.
iOS 12.4 may be one of the last updates to the iOS 12 operating system as Apple transitions to iOS 13, which is expected to be introduced at WWDC in June.
