If you are a OnePlus 2 owner and waiting for Android Marshmallow update to arrive, then here is something to cheer about for you. As per an Android Police report, one user has confirmed that OnePlus has started the Android Marshmallow update soak test for the OnePlus 2.
The user has shared a few screenshots to back up its claim which shows that the soak test update is OxygenOS v3.0.0 based on Android Marshmallow v6.0.1. You can see that there are a few visual changes in the screenshots. For example, you can notice that there are some new wallpapers which are not available on the current OxygenOS available for the OnePlus 2.
Now, if you are wondering when will the stable Marshmallow build for your OnePlus 2 arrive, then it may happen that you will still have to wait for some time. Last year, OnePlus had announced that the OnePlus 2 would receive the Android Marshmallow update by the end of the first quarter of this year. There is still some time to go for it, so keep your fingers crossed!!!
