Screen not turning on for incoming calls

Restart the phone

Press and hold both the Power and Volume Up buttons for at least eight seconds until you see the OPPO logo.

Remove the phone case and screen protector

Third-party screen protectors and cases may block the sensor and should be removed. We recommend our customers only to use the original case and screen protector.

Perform Component Check/Common Problems Detection

Check for sensor error using Common Problems Detection in Phone Manager. If detection results for Light Sensor returns Error or Not Detected, contact OPPO Support Team or take your phone to the service center.

For ColorOS 12 and above

1. Go to [Tools] folder > [Phone Manager] ＞ [┆] ＞ [Diagnostics] 

   

2. Select [Sensors] and disable other components. Tap [Run diagnostics] and follow the on-screen instructions to check if your Light Sensor works properly. 

For ColorOS 11:

Go to [Phone Manager] > [Diagnostics] > [Continue]. Select [Sensors] and disable other components. Tap [Run diagnostics] and follow the on-screen instructions to check if your Light Sensor works properly.

For ColorOS 6.1 to 7.2

Go to [Phone Manager] >  [Quick Check] > [Start Check]. Select [Sensors] and disable other components. Tap [Check] and follow the on-screen instructions to check if your Light Sensor works properly.

Use default Phone app and lock screen apps

Uninstall third-party call or lock screen application and use the default Phone app or lock screen passcode.

Update the phone software

Go to [Settings] > [Software Updates] and update your phone to the latest software version.

* DO NOT root your phone yourself, for that might affect phone’s system performance, and the warranty service will be terminated.

Reset the phone system settings

Go to [Settings] > [Additional Settings] > [Backup and Reset] > [Reset to Factory Settings] > [Reset System Settings Only]. (This option is available with devices ColorOS 3.2 and above).

Reset the phone to factory settings

Back up and transfer your data, then perform factory data reset. Go to [Settings] > [Additional Settings] > [Backup and Reset] > [Reset to Factory Settings] > [Erase All Data]/[Erase All Content and Settings] and follow the onscreen instructions to restore your phone to its factory settings.

If the abovementioned steps do not fix your concern, prepare your warranty card and contact your nearest OPPO Customer Service. You can also contact OPPO Support so we can help and assist you further with your concern. Depending on your region, you may check if you need to book an appointment before visiting your local Service Center.
