Motorola has started a soak-test of Android 5.1 Lollipop for the first generation Moto G 4G in the United States. David Schuster, senior director for software product management at Motorola Mobility confirmed the update.
As expected, Android 5.1 features Material Design. Notifications have also been changed to intelligently present the most important ones first. The Quick Settings in the notification tray will now offer Flashlight feature.Source (1) | Source (2)
