What's wrong with the automatic call screen of oppo mobile phone?

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 and 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.

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 local official OPPO service center for testing and processing.
