OxygenOS Open Beta 3 (Android 7.1.1 Nougat) rolling out to OnePlus 3 and 3T
Well, that shouldn't be an issue any longer, as the Chinese company has just announced a similar update is now available for OnePlus 3 and 3T users that run Android Nougat based on OxygenOS.
For example, there's a new Shot on OnePlus wallpaper option, which will allow you to change wallpapers automatically on a daily basis. The Gallery has gone through some change as well, so you'll notice that there's a new editor with watermark and photo straightening options.
According to OnePlus, there are a couple of known issues, but at least one of them can be fixed. If you notice that Android Pay is not working on London TFL/Tube, then you should update the app via Google Play. Sadly, it looks like there are still compatibility issues with specific third-party apps, which haven't been named.
If you're running an Open Beta build, then the new Android 7.1.1 Nougat based on OxygenOS will arrive on your OnePlus 3 or 3T via OTA. Otherwise, you will just have to flash the new build by ADB sideload.
