Correct the title, and version 3.1.9 not 3.2.0

I noticed that there is a bug, with version 3.1.9 Teamspeak
on Android.

The problem is that if I open the teamspeak app, and I connect to a server, then even if I close the app, and I receive call on the phone, the caller, does not hear me when I speak, but I hear him, and as if the microphone becomes mute, and to solve I have to restart the phone.

I have the LG Phone K10 2017, Android 7.0

Solve please, and very annoying.
