The Droid Turbo 2 employee edition has the Android 6.0 update since December last year, but now the software is available to the wide public.
You'll need to be on Wi-Fi to download it.
As usual, the update brings new function such as Now on Tap, additional modes for better battery performance, better storage system, expanded volume controls and much more. The build will change its number after the installation to 24.14.9.
