I'm having trouble with sound

For iOS users:

We added an advanced menu with options that help your device use a different microphone.
If others can't hear you, or there's static in your Polos, try these steps:
1. Tap the  Settings icon on the bottom of the home screen
2. Select Advanced 
3. Tap on Microphone
4.Select a different microphone, typically switching to the bottom mic will help. It may help to try another mic if selecting the bottom mic doesn't help.

For Android users:
If you're not hearing any sound when watching or recording a Polo, please try restarting your device.
