What are the unknown tips of iPhone?

This is a very clever function of hiding photos. Long press the photo and select "Hide". After hiding, the hidden photos will not appear in the collection and year, but will be stored in a hidden album that only you can see. So no one will know which photos you took with your iPhone.

2, SMS mute

IOS 8 can silently receive messages from designated people. 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. This function makes the information you don't want others to see inconspicuous, which is more convenient than hiding all the information.

3, more text control

IOS 8 has developed more short message editing and receiving functions, including deleting short messages in batches. Press and hold the selected SMS, and the options of "Copy" and "More" will appear. Click "More" to forward the selected SMS to others or delete it.

4. Credit card scanning

When you shop through Safari browser, you will find an option to "scan credit cards" instead of manually entering credit card information. This function will automatically appear on the keyboard. After selection, put your payment credit card into the lens area of your mobile phone, and it will safely input your personal information.

5, black and white mode

For those mobile phone users who want to experience the retro feeling, enter "General" and click "Accessibility" to open the "Grayscale" mode. Every software and email on the main screen of the mobile phone will be displayed in black and white.

6. Interactive reminder

You don't have to stop working when replying to text messages, emails, calendar reminders and messages. When you receive a text message or email, a reminder sign will appear at the top of the screen, and you just need to slide the reminder down to reply. Yes, this is the best new feature of the iOS 8 system.
