Motorola has just announced that the Android 5.1 Lollipop update for the Moto X (2014) is currently rolling out on several U.S. carriers. Customers of Verizon, AT&T and U.S. Cellular can now access the update on their smartphones.

Last week, Motorola announced that the Moto X (2014) would be receiving an update to Android 5.1 Lollipop: "We are excited to announce a new software update for Moto X (2nd gen) by Motorola. This update brings Android 5.1 Lollipop to your phone along with other improvements. Android 5.1 Lollipop improves stability and provides better control over notifications."

Now, the company has confirmed that the Android 5.1 Lollipop update is currently rolling out in various stages on several top U.S. carriers. David Schuster, vice president of Product Sales and Operations at Motorola Mobile Devices Unit, has announced that the update is ready for customers of Verizon, AT&T and U.S. Cellular.

Schuster, who has acted as the defacto spokesperson for recent operating system updates on Motorola devices through his Google+ account, announced that the Android 5.1 Lollipop rollout for the Moto X (2014) on U.S. Cellular is now being fully deployed. The carrier published release notes for the update in May, and last week, Schuster confirmed the soak test for the device on the network, which was apparently successful enough to engage full deployment.

Schuster also announced that the previously announced soak test for the device on Verizon has been expanded, and Android 5.1 Lollipop is now available for open pull. "Open pull" means that users of the smartphone on the network can access the update manually via the settings menu.

A full soak test for the Moto X (2014) on AT&T was also announced to be deployed today, and then later, Schuster updated his notes to announce that the Android 5.1 Lollipop update on the network was also available for open pull.

The Android 5.1 Lollipop update for the Moto X (2014) will include fixes for various bugs and issues in addition to several performance improvements. The update will also include user device protection, which prevents anyone other than the owner signed in with their Google password, from using the device, even if the smartphone is factory reset.
