What happen when your iphone black screen but still on?If your mobile phone screen has suddenly turned black and you can't fix it, it does not mean that the mobile phone is broken.Below we introduce some situations that make you phone screen black.

1.Environment temperature.Most smartphones use lithium batteries with a working temperature of -20℃~60℃. When the mobile phone is exposed to a super low temperature for a long time, the mobile phone will consume electricity in a short period of time, or shut the phone down by itself.The same is true in a super high temperature environment,the phone may be overheating and suddenly turn black. If the black screen of the mobile phone cannot be turned on due to temperature problem, you can change the environment to normal temperature, charge the mobile phone, and then it can be turned on normally.

2.System crashes.Smartphones are built-in "software systems". When a user installs too many Apps or runs multiple software, it will cause the system to malfunction. The most common malfunction is a crash. At this time, the screen of the mobile phone does not light up and it goes black. In this case, you can press and hold the power button for 3 to 5 seconds, turn off the phone, and then reboot.

3.Display failure.Vibration caused by collision or fall of the mobile phone will easily make the cable of the screen to loose, which will lead to the separation of the screen and the frame of the mobile phone, and the screen will fail. This is a hardware problem and it needs to be repaired in a repair shop.
