What is the black screen of OPPO mobile phone?

If you are using an OPPO/ One Plus mobile phone and a black screen appears, you can follow the following steps to troubleshoot:

1. If the phone is not full of liquid, both the power button and the volume button can be used normally. It is suggested that after charging 15 minutes, press and hold the power button+volume up button 12 seconds to restart the phone.

2. If multiple applications have black screens, it is recommended that you clean up the programs running in the background to ensure that the storage space of the mobile phone is greater than 10% to avoid unsmooth running or slow loading.

3. When the mobile phone system version is low, the application version may be incompatible with the system. I suggest you try to upgrade your mobile phone system to the latest version.

4. If this problem occurs after downloading the third-party application, it is recommended that you uninstall the third-party application to see if it can be restored.

5. If a single application has a black screen, it is suggested that you "long press the application icon >; Application information (application details) > application permission ",to check whether the application permission is turned off or turned on.

6. After the application is used for a long time, it will store a lot of data. It is recommended that you try to clean up the application data as needed (which will result in the loss of application data).

7. If the power button is pressed for a long time and vibrates, but the display screen is black, it may be a hardware problem of the screen. It is recommended that you take your mobile phone and purchase certificate to the official service center of OPPO for testing and handling by professional engineers.

If the distance sensor at the receiver is blocked during the mobile phone call (such as answering near the ear), the screen will be black at this time, which is a normal situation designed to prevent accidental touch; If the distance sensor is not blocked during the call and the screen of the mobile phone is black, I suggest you try the following operation methods:

1. Check whether the film covers the distance sensor and tear it off for observation.

2. If the mobile phone system version is not the latest, it is recommended to upgrade to the latest version.

3. Back up the important information of the mobile phone (contacts, text messages, etc.). ), restore the phone to the factory settings to see if the phone can return to normal.

4. If the mobile phone has a black screen in the horizontal game interface or other interfaces after the WeChat voice call is connected, this is the anti-misoperation design of WeChat. It is recommended to switch the WeChat voice phone to speaker mode after answering.

If the above methods can't be solved, please back up your mobile phone data and bring your mobile phone, invoice and warranty card to the official service center of OPPO for testing and processing.
