I can't send voice messages in a game. What can I do?

Please try the below:

1. Go to Settings > Security & privacy > Privacy > Permission manager > Microphone to confirm whether the game has a microphone function. If yes, turn it on.
2. Please check your network connection.
3. In game App, go to App info > Storage & cache > Clear cache, and clear the data.
4. Uninstall and reinstall the game.
