Here's How to Fix Some Problems You Might See in iOS 10

Did Touch ID stop working for you after updating to iOS 10? You can do two things to fix this. First, go to Settings > Touch ID and Passcode and turn off the option for "iTunes and App Store," and then turn off and on your iPhone. If that doesn't work, go to Settings > Touch ID and Passcode and delete your fingerprints. Add them again and Touch ID should work!
