Your question is a little confusing are you asking about the pb310 or your phone? What’s not working? If you are talking about the speaker download the JBL app you probably need a software update. Also there are buttons on the speaker where you can change the mode of the speaker from AUX to Bluetooth and to USB.
Sorry, there was a problem. Please try again later.Download the JBL app on your smartphone and you can control everything.
