Hello, I'm very sorry for the inconvenience. This situation is caused by the modification of some parameters in WeChat version 5.4. We are currently communicating with Tencent to solve the problem. Before that, you can enter Settings-More Settings-Application-Factory Program Management, find the WeChat version (5.2) that comes with the system, and cover the installation will solve the problem temporarily. This operation will not cause your WeChat chat history to be lost. Please feel free to operate. After solving the problem, we will achieve compatibility with WeChat version 5.4 through online upgrade.
If you have any questions, please feel free to consult us. Thank you very much for your support of our vivo. I wish you a happy life!
