Lenovo bright enough to continue to support xp apps on its hardware!!!
After launching the second generation of the Moto X in September and manufacturing Google's new flagship smartphone in the Nexus 6, Motorola has launched its own flagship phone in the Droid Turbo.

Motorola was acquired by tech giant Lenovo, which plans to use the Motorola Mobility brand to expand its reach into the U.S. market. Lenovo is one of the top smartphone vendors in its local China market, and is the third largest vendor in the world. The company plans to use the Motorola Mobility brand to expand into the United States.

Camera and sound recorder work flawlessly on the TracFone LG L39C. Not so on the 840G. But audio quality better on 840G.
I tested Lollipop on Google’s new Nexus 6 phone, released this week. I can only hope that as other phones get the upgrade over time, it will be as good as what you get on the Nexus.

It’s a shame many phone manufacturers that use Android believe they have to tweak it extensively to make the software theirs and not Google’s.
