In the previous/recent versions of the Android Teamspeak app (pre 3.1.9), when using hands free mode, i.e. using the loud speaker, incoming voices were automatically cancelled out and would not transmit back through the mic. This of course is optimal. In the most recent version, 3.1.9, any incoming voice is instantly picked up by the microphone, no matter how much I change the voice activation level or any volume level. There doesn't seem to be any sort of echo cancellation changes in the changelog, and there's certainly no option for it in the settings. This is making the Android Teamspeak app unusable unless push-to-talk is enabled, when this was not the case before this update. Is this a bug?
