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 13.2 Beta Includes Icon Depicting New AirPods Design
Today's iOS 13.2 beta release includes an icon showing redesigned AirPods that appear to have rubber ear tips that would likely be needed as part of a noise cancelation feature.
The file name includes reference to a B298 code name, and the image is contained in the Accessibility Settings folder. This could suggest these new AirPods will contain a new accessibility feature such as being able to use them as hearing aids, or it could be related to existing Live Listen capabilities.
There's no specific word on when the new AirPods could debut, but Apple has a number of rumored pending announcements that could point toward an October media event.
Update 11:55 AM: As noted by a MacRumors reader, a claimed photo leak last month from 52 Audio bears a strong resemblance to the image found in iOS 13.2, suggesting the leak may be accurate.
