An app isn't working

    If an app on your device isn't working properly, try these actions one after the other. Verify after each action whether the problem was solved before trying the next one.


    Downloaded apps that you have not downloaded on Google Play may not be fully compatible with your device. If the following actions do not solve the issue, contact the developer of the app for further information.


    The following steps may differ between Android versions. To learn which Android version your device has, find and tap Settings → About phone → Android version. If you do not see About phone under Settings, tap System.

These include rendering performance, screen brightness, image enhancement, and GPS while the screen is off. Synchronizing of background app data or streaming may be disabled for some applications.
