The oppor11 phone screen won t open

It may be caused by the failure of the third-party software installed in the phone, and the following methods can be taken to solve the problem:

1. When the phone is completely turned off, press and hold the volume down + power button for about 8 seconds (the phone will automatically enter the official recovery mode), select Wipe Data Factory Reset to restore factory settings, and then restart the phone.

2. If there is still a problem with the mobile phone, you can flash the phone and flash it into the new system.

You can go to the line brush to try the line brush.

The phone screen suddenly went black.

Finish? I'm more anxious than you, follow my guidance, let's try to deal with it first!

1. If the mobile phone is not liquid, the power button and volume button can be used normally, it is recommended that you charge for 15 minutes, and then press and hold the power button + volume up button for 12 seconds to force restart the mobile phone.

2. If multiple apps have a black screen, it is recommended that you clean up the background running programs to ensure that the storage space of your phone is greater than 10% to avoid unsmooth operation or slow loading.

3. When the mobile phone system version is low, there may be incompatibility between the application version and the system, it is recommended that you upgrade the mobile phone system to the latest version.

5. If a single app has a black screen, it is recommended that you press and hold the app icon > App Info > App Permissions to check whether the app permissions are turned off and turn on app permissions.

6. The application will store a large amount of data after long-term use, it is recommended that you try to clean up the application data as needed (it will lead to the loss of application data).

If the above methods cannot solve your problem, it is recommended that you bring your mobile phone and purchase voucher to OPPO customer service center for testing and processing by professional engineers.

This is available for all OPPO models.

No matter how you press it, how you point it, it's not good, you're in a hurry, don't worry, let's try these methods!

1. It is recommended that you remove the tempered film.

Turn off your phone and try to restart it. If there is a blister between the screen and the film, it is easy to cause the touch to fail. If both the power on button and the volume button + and - button (physical buttons) are out of order, you can try to force restart your phone by pressing and holding the power button and the volume + button at the same time for 10 seconds.

2. If the back button, menu button, home button, and power button of the mobile phone are not sensitive or cannot be used, it is recommended to uninstall and delete the recently installed software.

3. If you use the back button to go back to the previous interface or exit when running a program, it is recommended to click the home button to return to the standby interface and re-enter the program.

4. If it is simple to destroy the power on and off buttons and volume buttons that are prepared for early destruction, it is not easy to press, and the keys are damaged, please go to the OPPO customer service center for repair.

If you still can't restore after trying the above methods, you can back up your phone data and restore your phone to factory settings.

Or please bring the purchase voucher and mobile phone to the nearest OPPO official service center for testing and processing.
