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 Creates Tool to Check Activation Lock Status on iOS Devices
Accessible via iCloud.com, the Activation Lock Status Checker allows users to enter a Device IMEI or Serial number to check whether a device has Activation Lock turned on.
Activation Lock was introduced alongside iOS 7 and is designed to prevent iPhones and iPads from being stolen. When Find My iPhone is enabled, it effectively locks an iOS device to a user's Apple ID account, and even when wiped, the device will require the original Apple ID and password.
Activation Lock has cut down on iPhone-related thefts in major cities, but it has also affected users who purchase an iOS device used. If Activation Lock is enabled, a used iOS device will be entirely useless until unlocked by the original owner.
If an iOS device does have Activation Lock enabled, Apple's tool will give users a clear warning that an Apple ID and password will be required before another user can activate the device. It also provides instructions on how to remove Activation Lock from a used device, which requires contacting the previous owner.
Anyone who is purchasing or selling a used iOS device should find Apple's new tool very useful, as it can be used before a transaction takes place to ensure the iOS device will be usable by the new owner.
