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.

Apps Are Using Background App Refresh to Send Data to Tracking Companies
The Washington Post's Geoffrey Fowler teamed up with privacy firm Disconnect and used specialized software to see what his iPhone was doing and when. And while it's no surprise that apps are using trackers and sharing user data, the frequency with which apps took advantage of background refresh to send data off to tracking companies is surprising, as is some of the data shared.
Fowler found that apps were sending data like phone number, email, location, IP address, and more.
During the course of a week of testing, Fowler ran into 5,400 trackers, mostly found within apps, which Disconnect told him would likely send 1.5 gigabytes of data over the course of a month.
Trackers within apps, for those unfamiliar, serve different purposes. Some analyze user behavior to let apps streamline advertising campaigns, combat fraud, or create targeted ads. Delivery app DoorDash, for example, was found using a whopping nine trackers in its apps, sharing data like device name, ad identifier, accelerometer data, delivery address, name, email, and cellular phone carrier.
DoorDash also has trackers from Facebook and Google Ad Services, which means Facebook and DoorDash are notified whenever you're using the DoorDash service. DoorDash is not alone in sending tracking data, nor are the apps listed above - using tracking information is standard practice - but most people aren't aware that it's happening.
Not all data collection is bad, such as when it's anonymized and stored for a limited period of time, but some trackers are collecting specific user information and don't provide clear information on how long that data is stored nor who it's shared with.
As Fowler points out, there is no way to know which apps are using trackers and when that data is being sent from your iPhone, nor does Apple have tools in place that give iPhone users a way to see which apps are using trackers and for what purpose. Apple was contacted for comment, but provided a standardized privacy response.
"At Apple we do a great deal to help users keep their data private," the company says in a statement. "Apple hardware and software are designed to provide advanced security and privacy at every level of the system."Fowler suggests Apple could require apps to label when they're using third-party trackers, while privacy company Disconnect suggests greater privacy controls in iOS to give users more control over their data.
"For the data and services that apps create on their own, our App Store Guidelines require developers to have clearly posted privacy policies and to ask users for permission to collect data before doing so. When we learn that apps have not followed our Guidelines in these areas, we either make apps change their practice or keep those apps from being on the store," Apple says.
iOS users concerned about the data apps are sending, especially at night and without user knowledge, can turn off Background App Refresh in the Settings app and can use a VPN like Disconnect's Privacy Pro to limit the data apps are able to send to third-party sources.
