A few hours ago, Verizon was spotted hosting a software support page detailing the Android 6.0 Marshmallow update for the Motorola Droid Turbo 2. In the meantime, the carrier took down that page, but not before the information was able to spread. Please note that we're not sure what this means in terms of rollout, but all signs point that the update is imminent.
Android 6.0 Marshmallow is a major update that brings enhancements such as the battery-saving Doze mode, Google Now on Tap, manual control over app permissions, and a volume control system that actually makes sense, among others.
On top of these standard Android 6.0 Marshmallow features, the update for the Motorola Droid Turbo 2 will also bring a few device-specific changes. The Ambient Display feature is now gone, being replaced by Moto Display. Furthermore, the update will bring new Moto Assist functions as well.
Due to the size of the update, you'll have to keep close to a Wi-Fi connection to download the new software, which is expected to roll out in batches. The Turbo 2 will notify you when the update is available, but just in case you need to manually check for its existence, head on over to Settings>System updates.
