iphone 8p What is the reason for the black screen ?

One situation where the iPhone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to an unstable automatic shutdown, which is because the machine is of poor quality, resulting in shutdown for no reason. Because there is no big problem with the hardware, you can just press and hold the power button and wait for it to turn on.

The second scenario. DFU mode is the mode in which the Apple system cannot be turned on if there is a problem, while entering the recovery mode can be recovered with iTunes. But the phone is fine, and it can't be turned on because it can't be turned on because it has entered DFU mode by mistake, but it's actually very easy to solve.

You only need to press and hold the power button and the home button at the same time and wait for the iPhone to react, generally for more than 10 seconds, if there is no response for tens of seconds, the following steps continue.

In the third case, you need to enter DFU mode, first of all, iTunes must be installed on the computer, and you can ** a new iOS system. Or restore files with a backup beforehand. Of course, during the recovery process, the computer can be connected to the Internet, and it can also be ****, but the wait is longer.

There are too many reasons for the black screen, the motherboard is broken and can't be turned on, the battery is broken and can't be turned on, the screen can be black, it is recommended to send the repair official, do not repair the phone on **.

The iPhone automatically restarts by first finding the settings on the main page of the phone and opening it. Then tap "General", find "Restore" and tap it. Finally, click "Erase All Content and Settings", and click "Erase Now" in the pop-up window.

First, the black screen appears randomly, about three times a day, it will automatically recover in tens of seconds to one or two minutes, and it can also be recovered by forced restart, not automatic shutdown and restart, like the system is suddenly stuck, and the black screen simply turns in circles; Second: the black screen mainly appears on iOS or later, and this system happened to be launched in December last year. Third:

The black screen issue may also occur on other models, but the probability is lower than that of the iPhone XR. Last year, there was also a batch of black screens in the iOS system.

When I got home, I remembered that my friends who had recently taken an iPhone had a black screen turning in circles, which were an iPhone 6P, iPhone 7P, and iPhone 8.

It's been a person who has been playing the machine for many years.,The first time my colleague's mobile phone iphone8 had a problem, it was the "power button" + "home button" to deal with.,I found that there was no effect.,I thought it had become a brick.。

Later, I encountered a 6p, and the "power button" + "home button" happened to be good again.

After encountering 7p today, the "power button" + "home button" is not good.

After checking it, I realized that different models require different operations.

1.Restore your iOS device to its original factory settings.

Open Settings General Reset All Settings to reset your iPhone to factory defaults, but still keep all apps and internal data, which is the fastest and most effective way to deal with it. Reminder, if there is still an abnormal situation after the reset, it is recommended to try to re-perform the reset.

2.Force a reboot.

For models earlier than iPhone 7, press and hold the "Power button" + "Home button" at the same time until the iPhone appears with a white apple icon.

On iPhone 7 7 Plus models, press and hold the Power button and the Volume Down button for a few seconds until the Apple white apple icon appears in the curly bend.

For iPhone 8 and iPhone 8 Plus models, press the "Volume Up" button, then the "Volume Down" button, and then continue to press and hold the power button until the Apple White Apple icon appears.

iPhone X, press the "Volume Up key" once, then press the "Volume Down key" once, and then press and hold the power button on the right side for about 10 seconds or so, until the screen appears with a white apple icon.

3.Modify the region.

Click on "Language & Region" and change the region to United States.

4.Modify the system date.

Click "Date & Time" to turn off automatic setting, and set the system time and date to before December 1, such as November 30. However, this method may affect the confusion of the ** time setting stored on the mobile phone, and it is not recommended to use this solution unless necessary.

1. The distance sensor function of the mobile phone makes it block the distance sensor at the top of the screen when making a call, and the screen automatically turns off with a black screen, which is a normal situation.

2. The distance sensor is not set correctly, resulting in a black screen. It is recommended to go to the settings of your phone, find the sensor checker, and re-check to adjust.

3. The mobile phone has turned on the power-saving function, and the light sensor system on the front of the mobile phone causes the mobile phone to be close to the head when playing **, and the light sensing system detects that the light is darkened, and the black screen is used to save power, and the mobile phone leaves the head, and the screen recovers.

4. When the distance sensor fails, it is impossible to correctly judge whether there is an object approaching, which may cause a misjudgment when dialing ** and then turn off the mobile phone screen, so it is recommended to send the mobile phone to the official designated repair center for maintenance.
