Has anyone downloaded the Mgo app? I downloaded it and it is a little slow but the problem is that whenever you use the app the volume buttons and mute button act up. I press the volume down button once and it just continously decreases the volume. Same with the volume up. I press the mute button and I have to wait a second or two before pressing it again to unmute. If I press it immediately nothing happens. When I exit the app, the volume and mute buttons work fine again.
