Mic likes to unmute itself without warning especially if you change sound sources. It also won't connect to Bluetooth speakers so your call in meetings are srickly on your phone. You can barely hear and you're paranoid the mic turns on the entire time. Good luck not touching the screen. Also the app stops working and kicks you out of your meeting if you disconnect from wi-fi. Or if you go in and out of wi-fi. So you have to keep switching to cell service.
