Thanks so much for writing, and sorry to hear you’re having issues listening.
Let’s try the following steps to troubleshoot the app (not to worry, your Pandora account and stations won’t be affected):
1. Update the app to ensure you are on the latest version of Pandora.
2. If you have a battery saver or task manager app, make exceptions for Pandora or try turning it off completely.
3. Clear data for Pandora in your phone’s settings.
4. Make sure the app is installed to the phone’s local memory.
5. Lower your audio quality in the Settings menu. To get to your Settings, open your Pandora app to the Station list, tap the menu icon, and select Settings.
-If you’re a Pandora Premium subscriber, select Audio Quality & Download.
-If you’re not a Pandora Premium subscriber, select Advanced and then uncheck Higher Quality Audio.
Then, try Pandora again. If the issue continues, please proceed with the following steps:
6. Uninstall and reinstall the app.
- From the home screen, tap on the menu or App Drawer, select Settings, and open your Applications folder (sometimes located under Device).
- Go to the Application Manager, scroll down and select Pandora, then Uninstall.
- Once that’s done, reinstall the app through the Google Play Store or Amazon Appstore. Finally, launch the Pandora app and sign in.
Keep in mind that the steps to find certain settings on Androids can be different depending on the type of Android phone you have, as well as what Android OS you are running.
If you’re having trouble completing these steps, try contacting your device’s manufacturer for further help navigating their operating system.
Let me know how it goes.
