How did Apple's mobile phone knock down the screen?

Whether Apple's mobile phone turns the screen upside down depends on whether the screen direction lock is on or off.

Screen direction locking switching method:

First, hold down the bottom of the desktop and slowly drag the screen up.

Step 2: After entering the control center, if the small lock icon of the shortcut switch is white, it is locked. Click to release the locked state.

When it is necessary to keep the screen upside down, click the small lock icon of the shortcut switch once to achieve the goal.

Here are some tips for using Apple's mobile phone:

1, click the plus sign under safari, and you can open one directly from the desktop after saving it to the home screen.

2. Apple has 270,000 applications and can normally install 2 160 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-If you don't enable the installation of the application, you won't have this icon when you return to the desktop, and you can also prevent the software from being dumped.

3. Are you still worried about listening to songs when you sleep, and will the songs continue to play after you fall asleep? In fact, you can choose to turn off the iPod regularly in the clock tool that comes with the iPhone: advance the "clock" that comes with the iPhone, then enter the "timer" and then enter the "when the timer ends", and find the "iPod sleep mode" inside to use it.

4. There is no backspace key on the surface of the calculator, but you can backspace by sliding left or right on the digital screen.

5. Some friends find that electricity is used very fast. In fact, you have opened something that is unnecessary and consumes power: Settings -WIFI- Off; Settings-Mail-Get New Data-Close; Settings-General-Location Services-Off; Settings-General-Bluetooth-Off; Settings-brightness-automatic brightness balance; In addition, at least one electric cycle is guaranteed every month (electric cycle: refers to the automatic closing of the handle when in use, and then continuous flushing for 6-8 hours).

6. Shake iPhone/iPod touch to play music randomly. The microphone on the original earphone, click Pause, double-click Fast Forward, and triple-click Back to rewind the song. Click Yes to the previous song and the next song, and press and hold it to be the same song.

7. When writing a short message, if you want to delete all the content, just shake the iPhone a few times and a window will pop up. Select "Cancel Typing" to delete everything without pressing and holding the delete key.

8. Press and hold the line control button, and you will enter speech recognition. You can call, for example, xxx. Or ask: which band is it? It's the same if you press the home button without wires. (3Gs/4 only)

9. Have you ever encountered a situation where you want to enter the unit symbol "degree" (small circle), but you can't find it? Now tell you: press and hold 0 on the numeric keypad and this symbol will appear!

10. A short message came, and many people nearby saw it intentionally or unintentionally. What should I do? To teach you: Settings-SMS Interface-Turn off the display preview. In this way, when the message comes, there will only be the caller's number or name, and people around you can't see your message.
