Apple's mobile phone suddenly went black, but what's the matter with talking?

The mobile phone running system is unstable, just add the volume button and the home button to force it to start.

1. Solve this situation first, the iphone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to the instability of automatic shutdown, because the quality of the machine is not good, which leads to unreasonable shutdown. Because there is nothing wrong with the hardware, just press and hold the power button and wait for it to start.

2. If there is something wrong with the Apple system, you can't boot, but you can use itunes to resume when you enter the recovery mode. However, there is nothing wrong with your mobile phone. People think it's a cell phone fault because you entered DFU mode by mistake. Actually, it's easy to solve the problem. Just hold down the power button and the Home button at the same time and wait for your iphone to respond, usually 10 second. If you don't respond for dozens of seconds, don't be persistent.

3.？ Then connect the phone with black screen to the computer with usb cable, press and hold the power button and the HOME button 10 second (preferably accurately), then release the power button in the tenth second (don't make a mistake) and keep pressing and holding the home button. It doesn't matter if there is a connection icon or a black screen on the screen. Itunes will respond to the recognizer, then press the shift key on the keyboard, select itunes to restore your phone, and then prompt that after the recovery is completed, the boot should be solved.

4. None of the above three can solve the problem of black screen, so it may be a hardware problem. We all know that hardware problems can only be fixed. Unless we are professional enough, we may damage the mobile phone. At this time, find a reliable shop to send it for repair.
