My second generation Moto G now has an update available for Lollipop! To check, go to Settings, then About phone, then System updates. Hopefully now or at some point in the near future it will show a screen like this:
The Lollipop update promises a lot of improvements, as listed on the Motorola website. As well as featuring a Material design, notifications will be improved, a flashlight built into the Quick settings, multiple user accounts on the phone, the ability to pin an app (perfect for stopping children getting access to other parts of the phone), a new battery saver mode and more. I’ll write another post once I’ve had a chance to try out Lollipop properly.
