Owners of the first-generation Motorola Moto G, released in 2013, would be happy to know that their smartphones will finally be receiving the long-awaited update to take the device's operating system to Android 5.0.2 Lollipop.

The update has long been in the making, with Android 5.0.2 Lollipop making its first appearance in devices back in December of last year.

The delay was more pronounced especially after an engineer in Motorola claimed earlier in January that the Android 5.0.2 Lollipop update for the Moto G 1st gen was already coming "really soon."

However, the longer wait time could also be seen as a good thing for first-generation Moto G users, as the delay should have given Motorola enough time to iron out the many bugs that have been associated with the early releases of Android Lollipop. As such, users are expecting that no such problems will be seen on their first-generation Moto G smartphones once they upgrade operating systems.

Included in the Android 5.0.2 Lollipop update for the first-generation Moto G are several changes in the user interface, along with the new features that were introduced in Android Lollipop. The details were discussed by Motorola on the official changelog for the Android 5.0.2 Lollipop update for the smartphone.

Foremost is Material Design, which is the new design language that Google has started implementing with Android Lollipop. There were also changes to the user interface for notifications, with the notifications that appear on the user's lock screen to be intelligently ranked depending on the source of the notification.

Users are also now allowed to set up several accounts on their smartphone, allowing for multiple people to share the same device. The call and text privileges of each user can be restricted depending on the owner of the device.

Upgrading to Android 5.0.2 Lollipop also adds a Smart Lock to smartphones, replacing the trusted devices feature of the first-generation Moto G.

The upgrade also makes performance enhancements to the device, with the smartphone to begin using the new Android Runtime upon upgrading. The new runtime will help in the optimization of the performance of applications, with apps undergoing a one-time process for optimization upon installing Android 5.0.2 Lollipop.

For the corresponding Android 5.0.2 Lollipop update for the 4G LTE model of the Moto G, Motorola said that the smartphone will no longer get an upgrade to this version of the operating system. Instead, the Moto G 4G LTE smartphone will jump directly to Android 5.1 Lollipop.
