Cam goes over five of the changes noticed in iOS 8 beta 5. It's the 5th iteration of the next generation of iOS and it comes with a few neat touches. Among them is a new toggle switch for predictive text, locations in photos, Medical ID on your lock screen and a couple more.
The most useful of the new set of features is the ability to have your Medical ID on the lock screen. This way, if someone finds you in need of medical attention, they have quick access to your medical details. They can see what conditions you may have, what medications you take and find an emergency contact to call without accessing any other part of your phone.
