Why can't WeChat make voice calls and videos?

Possible reasons why wechat can make voice calls but not video calls:?

1. The mobile phone didn't grant WeChat permission to use the camera?

2. The version of WeChat is too low or WeChat is not compatible with the current mobile phone. In this case, we just need to update to the latest version.

The specific operation steps of access are as follows:

Wechat version 8.0.32

Example mobile phone: Huawei p40pro

1, we open the settings in the phone, and then slide down to find applications and services.

2. After opening the application and service, click Rights Management.

3. Here we find the camera click.

4. Then scroll down in the camera page and find the WeChat click.

5. After clicking Open, we choose to allow clicking during use, so that we can open the permissions.
