9. Smart Invert
Accessible under Accessibility in General settings, Smart Invert changes and reverses the colour of the entire display, except for images, media and some apps that use dark colour schemes. It’s worth noting that this doesn’t replace the ‘Invert Colour’ functionality that’s already present in iOS 10.
10. iCloud family storage plans
If you and your family members own multiple Apple devices, and use them to share media such as photos, images and videos, it makes no sense for each member to have their own iCloud storage plan. Thankfully, iOS 11 makes it possible to have shared iCloud storage plans. Up to six members of a family can share a common iCloud storage plan between them. This can be done without having to pay any extra costs on a monthly basis.
