The OTA update MPD24.65-18 weighs roughly 590MB and is likely to reach other Moto X Play users around the globe soon. It is worth mentioning that the Moto X Style, which launched along with the Moto X Play, started receiving the update last month. Users can manually check for update via Settings > About Phone > System Update.
For those unaware, some of the new features of the core Android 6.0 Marshmallow update include revamped app permissions; Google Now on Tap feature; new Chrome feature that will change the Web experience for Android users; new ways to handle Web links; Android Pay mobile payment system; new fingerprint APIs for developers to add into their apps, New Silent feature for sound and vibrate mode as well as a 'Do Not Disturb' mode to block all sounds or only alarms and notifications, and battery saver features called Doze that will make Android devices smart about managing power.
Apart from the regular Marshmallow features, Motorola will be also pushing some Moto-specific changes that users will see after updating to the new Android OS version. Some changes to Moto enhancements include removal of Moto Assist feature as part of upgrade to Android M. The company explains that the latest OS includes an option for 'Do Not Disturb' under the 'Sound and notification' settings that performs similar function what Moto Assist does.
Motorola in December also started rolling out the Android 6.0 Marshmallow update to the Moto X (Gen 2) as well.
