Skills of using Apple 4s

1. When writing a short message, if you want to delete all the contents, just shake the iPhone a few times and a window will pop up. Select "Cancel Typing" to delete all contents without pressing the delete key for a long time. If you want to restore the content you just deleted, shake the iPhone and select "Redo Typing", and the content you just deleted will come back; If it is just pasted, you can "undo pasting" by shaking it. Users with two iCloud accounts get traffic by SMS, and there is no SMS fee.

2. Have you ever encountered such a situation: you want to enter the unit symbol "degree" (small circle), but you can't find it. Tell everyone: press and hold 0 on the numeric keypad and this symbol will appear.

3. A short message came, and many people nearby saw your short message intentionally or unintentionally. What should I do? Let's teach you:

Enter the Settings-SMS interface-close the display preview, so that when the SMS comes, only the number or the name of the caller will be available, and people around you will not see your SMS content.

4. Some friends find that electricity is used very fast. In fact, you have turned on some unnecessary power-consuming things: Settings-WIFI-Off; Settings-Mail-Get New Data-Close; Settings-General-Location Services-Off; Settings-General-Bluetooth-Off; Settings-brightness-automatic brightness balance.

5. Apple has 270,000 applications and can normally install 2 149 softwares. However, if there are too many softwares, they often need to be upgraded, which leads to the little red dot of the App Store icon, which is very eye-catching and troublesome to upgrade. I believe that most people have some feelings. It can be solved by setting. Settings-General-Access Restrictions-Do not enable the installation of applications, so when you return to the desktop, there is no such icon, which can also prevent the software from being misplaced.

6. Are you still worried about listening to songs when you sleep? Are songs still playing after you fall asleep? In fact, you can choose to turn off the iPod regularly in the clock tool that comes with the iPhone. Try the fruit powder you don't know yet! The operating steps are: advance the "clock" that comes with the iPhone, then enter the "timer", then enter the "when the timer ends", and find the "iPod sleep mode" inside to use.
