While much of the current Android talk surrounds Android N, there are a number of Android devices still waiting on the update to Android 6.0 (Marshmallow). Although Marshmallow updates have been rolling out fairly regularly for major flagship devices recently, there are some leading devices which are still waiting on their update. The OnePlus 2 being a prime example with its most recent update coming at the start of this month and as a minor update for Android 5.1 (Lollipop) in the form of OxygenOS 2.2.1. However, it could be the case that the OnePlus 2's wait for Marshmallow is about to come to an end.
Screenshots that have been passed on to Android Police today seem to show the OnePlus 2 running on Android Marshmallow, as well as highlighting a couple of the tweaks which will be included in the next update, along with a look at some of the new wallpapers too. According to the details, it seems OnePlus is in the process of soak testing the update which comes in as OxygenOS 3.0, based on Android 6.0.1 and including the March security update. While soak testing does typically mean that an update is near to its rolling out stage, it does not guarantee that it will happen anytime soon. Typically, these tests are dependent on whether any major bugs are found, which will likely determine how quickly the update moves from testing to rolling.
Of course, those who use a OnePlus device (which runs on OxygenOS) will already know that in spite of this being a skinned version of Android, it is one which is not that far removed from stock Android, so the assumption would be that there should not be any major issues with the update and once it has finished soak testing, its rolling out announcement should not be too far behind. If you have not seen this update rolling out to your device, then it is probably fair to assume your device will not be part of the soak testing. Either way, for those interested in seeing how Marshmallow is likely to look on the OnePlus 2, check out the images below.
