How to turn on the hidden function of iphone?

How to open the hidden function of iPhone: 1. Hide photos: This is a very clever function to hide photos. Long press the photo and select "Hide".

Click "Details" in the SMS conversation to open the Do Not Disturb mode, so that you can silently receive the SMS from the person you specify in the ringing mode.

More text control: iOS 8 has developed more short message editing and receiving functions, including deleting short messages in batches. Long press the selected SMS, and the options of "Copy" and "More" will appear. Click More to forward the selected message to others or delete it. 4. Credit card scanning: When shopping through Safari browser, you will find an option of "scanning credit cards" instead of manually entering credit card information.

Interactive reminder: When replying to text messages, emails, calendar reminders and messages, you don't need to stop your work.

Yes, this is the best new feature of the iOS 8 system. 7. Medical ID: IOS 8 provides a brand-new health software HealthKit with a medical ID card.

Timed selfie: The new system adds a timer to the camera, which can accurately capture the picture you want within three or ten seconds.
