Why does oppor9plus end the call as soon as the text message comes when answering the phone?

Hello, what type of mobile phone are you using? You can observe whether the SIM card signal displayed at the top of the mobile phone screen is normal. You can change the location and compare it with different contacts.

At the same time, you can take out the SIM card and reinstall it, or use someone else's SIM card to install it in your mobile phone to see if the same phenomenon exists.

Please observe whether the mobile phone is enabled with 4G network. This phenomenon occurs during a call. Please set it to 3G/2G mode in phone settings-general-network-preferred network mode, or directly turn off the data network before observing the call. Because of the voice fallback scheme adopted in the 4G communication scheme, when the 4G network is unstable, it may affect the call.
