Oppok5 incoming call black screen is not displayed.

OPPO mobile phone blocks the distance sensor at the receiver during the call (such as answering near the ear), and 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 blocks 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. 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.
