OnePlus is now rolling out the OxygenOS 4.0.1 dev preview to OnePlus 3 devices. We don’t have an exact official changelog for the update yet, but it’s only 36MB in size, so guess it’s just bug fixes and performance improvements.

OxygenOS 4.0 is based on Android 7.0 Nougat. After several beta tests, OnePlus rolled out the stable version OxygenOS 4.0 to OnePlus 3 and OnePlus 3T devices earlier this week.

OTA zip for the OxygenOS 4.0.1 dev preview isn’t posted yet, but it should be available shortly as the update rolls out to more users/developers. We’ll be sure to post the OTA zip on this page once we get hold of it.

If in case you’re still running your OnePlus 3 or 3T on Android 6.0.1 Marshmallow, you can grab the Nougat based OxygenOS 4.0 full ROM zip for your OnePlus 3 or OnePlus 3T from our update pages linked below:
