Motorola is dropping its signature software enhancements as part of the plan to update its phones to Android Marshmallow.

That means no more Motorola Assist, Migrate, and Connect add-ons bundled with your device. Motorola says that with all the new features in Marshmallow, they’re no longer necessary.
Assist handles voice commands, and is always listening for the phrase, “OK, Moto X” (or any phrase you set). Migrate transfers in contacts and other content from another phone. Connect lets you send SMS messages from a Chrome extension, which sync up with your phone.
On the Motorola Blog the company notes that Marshmallow takes on much of this feature set with its new features. Google Now already had an “always listening” capability if you enable this through the Google app and it's supported by your phone's hardware. Also, Google already had bumped up its own migration tools with Lollipop, making Migrate feel like a needless duplication.

And Motorola noted that many are switching to “over-the-top” messaging services like Hangouts or Facebook Messenger instead of texting.
