How to solve the black screen of oppo mobile phone call

If the distance sensor at the receiver is blocked during a cell phone call (for example, answering a phone call near the ear), the screen will turn black at this time, which is a normal situation 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 version of the mobile phone system is not the latest, it is recommended to upgrade to the latest version.

3. After backing up the important information of the mobile phone (contacts, text messages, etc.). ), restore the phone to the factory settings and see if it can be restored to normal.

None of the above methods can solve it. Please back up your mobile phone data and bring your mobile phone, invoice and warranty card to the nearest OPPO customer service center for testing and processing.

This answer applies to all OPPO models.
