What should I do if my vivo phone has a black screen and freezes?

Then there is only a way to reinstall your phone's system, and there is no other way.

I hope mine can help you, hope, thank you.

If the black screen of vivo smart phone does not respond, you can refer to the following reasons and solutions: 1. If the mobile phone system fails, press and hold the power button (for the full screen, you need to press and hold the "Power" button and the "Volume Down" button at the same time).

Will go to the after-sales service and let him fix it.

Causes

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the telephone meter to detect whether there is a change in the indication, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

Recommended when using a mobile phone:1: Try to pick up in an area with a good signal**;

2: Reduce talk time in areas with poor signal quality;

3: If you play for a long time, it is best to use wired headphones to call**.

In fact, the most important thing is not to play for too long.

There are several solutions to the black screen of vivo phones:

1. The phone screen is black due to too low battery

Generally speaking, the low battery of the mobile phone will prompt it to turn off automatically. But sometimes the power is depleted too quickly, and the black screen is directly shut down. So when you encounter a black screen on your phone, first consider whether it is because your phone is running out of battery. (If the temperature of the mobile phone is too high, wait for the mobile phone to cool down naturally before charging).

2. There are too many application processes in the background, resulting in a black screen of the phone

If there are too many applications enabled in the background of the phone, and the system running memory is difficult to load, it may cause the phone to freeze and go black. You can turn off and restart your phone and clean up the apps in the background. (If you can't press the power button to power off, you can try 'press and hold the power button for 10 seconds' or "power button + volume down button" to force restart).

3. Black screen caused by water ingress on the phone:

When your phone gets into water, don't shake it hard and don't restart it right away. It's best to get out in the sun and make sure the inside of your phone is dry before restarting your phone.

4. The black screen caused by the mobile phone being hit hard or falling from a high altitude, etc.:

If the mobile phone is hit hard by an external force, or after falling from a high place to the ground, the screen is black, and the phone cannot be turned on or the screen is not displayed after turning on, then most of the hardware has been damaged. It is best to leave it to a professional to handle the repair.

5. The black screen of the mobile phone caused by the outside temperature is too low

When the mobile phone is manufactured, the internal hardware is set up with a variety of temperature monitors. Once the optimal temperature range set by the system (generally 0-35 degrees Celsius) is exceeded, the system will often automatically shut down and black screen in order to protect the internal hardware of the mobile phone. Therefore, if the outside temperature is too low, you can consider warming up the mobile phone environment.

It doesn't matter if the black screen is black, restart the phone first and see if it can be solved. Then pay attention to what program is causing the black screen. If it's regular, it can be solved. If it is irregular, it is recommended to return to the factory for repair.
