If I use my smart device's other features (texts, social media, etc.) will I be disconnected?

No, if the application is updated to version 1.1.0 or higher, voice chat will continue in the background, even if you press the home button or sleep button on your smart device.

A notification will appear when the app is minimized to let you know when it is running in the background. If you wish to disable voice chat while remaining in the chat room, you can press the X button at the bottom of the chat screen to suspend voice chat.
