Enabling background data
Google Play requires you to enable background data in order to function properly.
To enable background data and auto sync on your device:
- Press Menu from the home screen, then visit Settings
- Under Wireless & Networks, select Data usage
- Tap the menu button in the top right corner
- Make sure "Restrict background data" is not selected and "Auto-sync data" is selected
Please note that on some devices, you'll find the background data option here: Menu > Settings > Battery data manager > Delivery > Background data.
