OnePlus has been working for several months to update OnePlus 2 to Android 6.0.1 Marshmallow and since yesterday at night we can give a look to the first fruits of this hard work thanks to some screenshots.
The Chinese company, in fact, is releasing an update to OxygenOS to some beta testers in order to see how the new firmware behaves on the field and this allows us to see some news that it brings. There really is not any more news in addition to Marshmallow: we find a new call setup Alert slider, to manage the priority of notifications through the physical slider, and small visual clues in the launcher, in particular regarding Shelf.
Specifically, it is the OxygenOS 3.0.0 based on Android 6.0.1 Marshmallow introducing all functional enhancements developed by Google for its operating system. First of all the new control system and management of permissions for applications, the Not-Disturb mode that blocks notifications and sounds, also Doze mode that optimizes energy consumption. All properly optimized from OnePlus as a way that brings some improvements to the launcher graphics and a new setting for notifications.
Do not know any other information on this release, whose release notes may be longer. Same goes for the official release which could begin later this month unless the beta testers do encounter bugs and malfunctions such as to compromise the user experience. In that case, there could be further delays. In any case, when the update is available you will be notified and just follow the onscreen instructions to proceed with the installation in the Firmware-Over-The-Air mode.
There seems to be more and this means that OxygenOS 3.0.0 should not differ much from OxygenOS 2.2.1. At this point we believe that the update roll out is pretty close and then the announced deadlines could be met.
