The OnePlus 2 has started receiving the Android 6.0.1 Marshmallow update in the United States. The over-the-air (OTA) update is being pushed in phases and the incremental rollout means it may be a few days before the firmware hits all units.

OnePlus said the update would be rolled out to all OnePlus 2 handsets within “48 hours or so.” Users can either wait for the OTA update notification or navigate to the Settings menu to manually check for updates.

Device owners are advised to have a stable Wi-Fi connection and at least 50 percent battery before downloading the software bundle. This update will change the Marshmallow-based OxygenOS version to 3.0.2.

The standard Android 6.0.1 Marshmallow goodness includes Doze Mode, which helps in saving stand-by battery life of the Android handsets by putting them to deep sleep after prolonged periods of inactivity.

Furthermore, OnePlus 2 will reportedly receive system wide performance improvements, along with enhancements to the fingerprint sensor to make it improve its accuracy.

The OnePlus 2 specific updates include new Camera UI and AF optimization. MaxxAudio and Tuner have been removed from the list of pre-loaded apps. However, OnePlus has integrated Dirac HD Sound technology in the speaker, promising excellent audio experience.

After updating to the Marshmallow OS, apps can be locked in “recently visited apps list”. OnePlus has also added “clear process” and “clear all” options to control background activities.

The Shelf UX has reportedly been improved and OnePlus 2 users can “long press” in order to edit a board. In addition, SwiftKey has been updated to version 6.3.3. Once the user selects a network operator, it will now “stick to your choice” to avoid accidentally using other networks.
