The mobile phone cleared the memory and found that WeChat could not send and receive messages.

Hello, I am very sorry for the inconvenience caused to your use! According to your description, first of all, I suggest you try to uninstall the third-party software you installed. If it still cannot be restored, in order to ensure the normal use of the mobile phone, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test it.
