Why can't my s9 WeChat send voice?

When qq, Momo, WeChat and other software cannot send voice, please follow the following steps:

1. Please confirm that the current network is available.

2. Try sending voice again with another contact.

3. Settings-Application Manager-All-WeChat /QQ- Clear Data.

4. Please uninstall WeChat /QQ software and try to reinstall WeChat /QQ.

5. Try to install another version of the software.

6. Try to restart your phone.

7. If all the above methods fail, please back up the data (contacts, text messages, photos, etc. ) and try to restore 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.
