What to do if the screen of the iPhone goes black

The black screen of the Apple phone can be simply summarized into several situations: the first one: the iPhone itself is a refurbished machine or other machines with quality problems.

Occasionally, there will be an unstable black screen, but not a broken screen. The second one: accidentally entered Apple's DFU mode, which is Apple's recovery mode.

Third: Maybe the Apple system won't start. Fourth:

The hardware is damaged and the screen is broken. Except for the fourth point, which really needs to be sent to an Apple repair point for repair, the rest are soft problems that can be solved by yourself. Fifth:

The iPhone itself is unstable, resulting in a black screen. This black screen can be attributed to the unstable automatic shutdown, that is, the poor quality of the machine leads to shutdown for no reason. Because the hardware is actually not a big problem, just press and hold the power button and wait for it to boot up.

Precautions for forced restart for iPhone users:1Many iPhone users are worried that the data in the iPhone will be erased after a forced restart.

Bian Xiao had to explain that a force restart would not erase the data from the iPhone. 2.If your iPhone still won't turn on after force restarting, you can try again with the following methods.

Here's how to get your iPhone's screen black back to normal:

Usually, the automatic brightness adjustment function is turned on, and the screen may be blackened because the outside light is too bright.

4. Amplifier: There is a very practical functional amplifier on the iPhone, which can use the camera on the iPhone to quickly zoom in on things. If you notice that the screen display flickers on and off while using this feature, you can turn off the amplifier in the accessibility function of your iPhone's settings.

5. Dark mode: In iOS 13 and newer systems, Apple has brought dark mode, and users can choose to turn on the feature during a specific time period. If you're not used to this mode, you can go to the Display & Brightness settings to customize the time when Dark Mode is on.

The reason why the screen goes black when the iPhone is hot:When the internal temperature of your iPhone is too high and is out of its normal operating temperature range, the device will try to adjust its temperature to protect the internal components. These changes occur when your iPhone adjusts itself:

Charging slows down or stops, the display dims or goes black, the signal becomes weak, and the camera flash is temporarily unusable.

Slower performance when using graphics-intensive or augmented reality apps or features. As the weather gets hotter and hotter, it is easier for your iPhone to overheat if you run graphics-intensive functions or apps for a long time when the ambient temperature is too high. In such a situation, it is recommended to pause the use of your iPhone, rest it on the desktop and wait for it to cool down.

Precautions for using Apple mobile phones.

Please use your iOS device in an environment where the temperature is between 0 C and 35 C. Using an iOS device in a cold environment below the operating temperature range may temporarily shorten battery life and may cause the device to shut down. When you bring your device back to a warmer environment, battery life will return to normal.

And using an iOS device in a hot environment may permanently shorten battery life.

If you see a temperature warning screen, it is recommended to turn off the device, then move it to a cooler environment to cool down and wait for the temperature to drop before turning it on. If your device will suddenly dim during use even when the temperature is normal, you can bring the device to Apple's official after-sales service after making an appointment for repair to further detect the cause of the problem.
