Changelist appears for first-generation Motorola Moto X Android 5.1 update
Because the update takes the first-gen Moto X directly from KitKat to Android 5.1, it includes all of the features we saw in Android 5.0 and those from Android 5.1 including Material Design animations, Lock Screen notifications, Smart Lock which allows you to unlock your phone when paired with a Android Wear powered device, and the 64-bit ART compiler which will open apps faster.
Also part of the update is the Battery Saving Mode which limits apps running in the background to extend your battery life, a new battery setting panel which shows how much time is remaining until your battery is dead and how much time is left until it is fully charged. The new Recent Apps menu is part of the update, and Quick Settings will now appear with a two-finger slide down from any page. Speaking of Quick Settings, a new flashlight feature can be found on that page.
This will be a good example of what to expect when Motorola starts updating the first-gen Moto handsets and the Verizon exclusive Motorola DROID Turbo from Android 4.4.4 to Android 5.1 like it has promised.
