LG has already started testing out the beta build for Oreo since November and it looks like they might be ready for the actual released soon. Also, if you install the Oreo beta, you will continue to get the beta software updates and switching to the stable release channel will require a clean flash, which means full data wipe.
You can download the ROM from here. The first Open Beta for OxygenOS has rolled for the new 5T and it brings with it the first taste of Oreo on the phone. The company confirmed that the OxygenOS 5.0, which is based on Android Oreo, is reaching OnePlus 5 users. However, the tweet suggests that it could be available in the coming days days.
In total, not many devices are running Android 8.0 Oreo, at least comparatively.
Once the open beta goes live, the company expects that a lot of OnePlus 5T owners will upgrade their handsets.
OnePlus has added all the Android Oreo features in this update. The brand's products are sufficiently capable of taking on the latest models from the competition. It sports a "unique" 5.7-inch "FullVision" display that has a resolution of 1440x2880 pixels. There is also an 8GB + 128GB variant available for Rs 37,999. In a nutshell, the new Oreo update will completely change the OnePlus 5T smartphone's actual UI. The biometric unit is now located on the rear panel of its metal chassis. While it managed to keep its promise to push out an Android 7.0 Nougat update for the OnePlus 3 and the OnePlus 3T before the end of 2016, it's broken others, including a promised Nougat update for the OnePlus 2.
