After months of waiting, Motorola has started rolling out Android 5.1 Lollipop update for Droid Turbo. Verizon Droid Turbo users will receive the OTA (over the air) update shortly on their device which will update the device from 4.4.4 KitKat to 5.1 Lollipop. As the firmware is rolled out in phases, it will take few days to reach the update on your device.
If you have not received the OTA update notification for Android 5.1 on your phone, you can check it manually by going to phone’s settings -> about phone -> system update. However, your Droid Turbo should be running on stock Android 4.4.4 KitKat with locked bootloader.
Along with Android 5.1, the update will also bring many improvements and new features like Material design, new device protection, smart lock, app pinning, better battery management, smart internet, new quick settings menu, flashlight, Moto Display + Ambient display, Moto Assists & Downtime, and more.
If you have not received the OTA notification for some reasons, you can update your Droid Turbo manually by downloading the update zip file. Some folks have captured the official Android 5.1 Lollipop OTA zip file for Verizon Droid Turbo that you can download and install manually.
