Why can't Samsung S8 always receive QQ messages?

If mobile QQ can't receive information, it is suggested that:

1. Check whether the network is in good condition and try to use a stable wireless network if possible.

2. Please try to update the QQ version.

3. If the QQ software is downloaded by yourself, it is recommended to uninstall it before trying to download it.

4. If the phone comes with its own software, please back up the data (contacts, text messages, pictures, etc.). ) and try again after restoring the factory settings.

If the problem still exists, 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.
