OnePlus reveals Android Marshmallow upgrade schedule for its devices

OnePlus owners will have to wait until next year to get the latest and newest Android upgrade. The Chinese start-up has just revealed the Marshmallow upgrade details for its flagships.

Last year's OnePlus, which is currently running Cyanogen OS 12.1 featuring Android 5.1.1, will receive Marshmallow in the first quarter of 2016, which is sometime between January and March, though the company has not given a specific date for the rollout. The phone which originally ships with Cyanogen OS, also supports the company's native-grown firmware, OxygenOS. However, OnePlus promises to update its custom OS.

The OnePlus 2 will also be updated around the same time as the OnePlus One. While there are no details about the new features Marshmallow would bundle for OnePlus One, the update for OnePlus 2 will include Marshmallow API for fingerprint sensor.

"We've heard requests for us creating an API for the current fingerprint implementation in Oxygen OS, but have decided against this since we're switching over to the standard Android M implementation soon," asserts the company.

However, the company has been working on improving fingerprint authentication on OnePlus 2. Oxygen OS version 2.0.2 seeded last month added improvements for fingerprint recognition accuracy, following users' complaints about the non-responsive fingerprint scanner, where they had to unlock the phone manually using pattern or passkey as the fingerprint would not respond. Some were even forced to use On Screen Navigation as that helps to keep the issue under control.

As for the OnePlus X, the company says: "We are working hard to bring Marshmallow as soon as possible to the OnePlus X, and will update you on a time frame at a later time."
