OnePlus has announced that OnePlus 8 and OnePlus 8 Pro users will now have access to try out the Android 11 Developer Preview 3 and get a first look at the refreshed design and features of OxygenOS 11.
Android 11 Developer Preview 3 is designed for most technically-inclined community members to test out the new features and share feedback directly to OnePlus. As this is still in an early stage of development, we do not recommend flashing this ROM if you have little to no experience in software development or flashing custom ROMs, or if you expect to use the device as a daily driver. As always, proceed at your own RISK!
