The long-awaited Marshmallow update for the Droid Turbo 2 appears to be actually pushing out. This is following a previous announcement of a soak test and roll-out that don't seem to have gone according to plan. Motorola's Product Manager, David Schuster, took to Google+ to say that it is now pushing.
I'm pleased to announce we have started soak testing with the Android Marshmallow 6.0 upgrade for Droid Turbo 2 on Verizon. We will monitor for a few days and with good results, proceed to full deployment.
If you own the Turbo 2, and didn't receive the Marshmallow update previously, you will want to check for the update now. To check manually, head into your Settings, then About phone and finally check for the update. If you receive the update, be sure to let us know how it is treating you.
