(Hint: iPhone put the liquid touch indicator on the SIM card, after taking the card, if you see a red or pink dot, it means that there is water, under normal conditions, it is white or silver).

Solution 2 for Apple 8 8plus Black Screen of Death:

Try to turn it back on, press and hold the power button and the home button at the same time to hard shut down the device and then turn it on until the white apple logo appears.

Reasons for the black screen of the iPhone:

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.

In general, it may be due to the battery running out, resulting in a black screen that cannot be turned on. If this is the case that we can't turn it on, please connect the phone to the power first, if you see a charging sign on the screen at this time, and the battery is very low, it will be scattered because the battery is dead.

Some friends think that when they are connected to the power supply, they can turn on normally after charging again. In fact, if you use up all the power of the battery, the charging needs to be charged to 5% before it can be turned on normally. So in this case, please let the phone charge for a while before turning it on.

If you are sure that the current battery of your phone is sufficient, but it cannot be turned on normally, there may be a problem with the software system of the hand-held phone. It is recommended to bring your mobile phone to a regular Apple customer service center for inspection and repair.
