When you add your Google Account to LYF mobile device, the data that you previously backed up for that Google Account is restored to the device. You can choose to restore app settings when you reinstall an app on your LYF smartphone. This feature requires that you have already backed up your data with your Google Account and that the app also uses the Android Backup Service. Some apps may not back up and restore all data. Steps to restore app settings on your LYF mobile device:
1. Open your device's Settings menu.
2. Under "Personal," touch" "Backup & reset".
3. Touch “Automatic restore” to switch it on
