OnePlus has started rolling out a latest and surprising update to the OnePlus 3 closed beta group. The update is weighing at around 800MB and it brings Android 8.0 Oreo for OnePlus 3.

The latest Android 8.0 Oreo update, unsurprisingly, isn't stable - NFC isn't functional yet, WiFi is buggy, hotspot and Bluetooth are unstable, and so on. The OnePlus is trying to roll out the stable build by mid-September. It's worth mentioning that the OnePlus 3T and OnePlus 5 closed beta groups are also expected to get the Oreo update soon. Time-frame for their respective stable builds is similar to the OnePlus 3, which is mid-September, as reported by GSM Arena.

However, several reports mention that it is a bit surprising that OnePlus 3 has received Android 8.0 Oreo closed beta before OnePlus 3T and OnePlus 5 that are newer flagship from the Chinese company. Following the rollout in the mid- September, OnePlus could be the first smartphone player to offer Oreo update for its devices, as reported by Indian Express.

Google has started rolling out Android 8.0 Oreo to its Pixel, Pixel XL smartphones across the world earlier this month. Apart from Pixel device users, those who have Google Nexus 5X, Nexus 6P, Nexus Player, or Pixel C tablet can also get this new OS on their smartphone. Android 8.0 Oreo brings several features to the device, some of them are an improved battery performance, picture-in-picture option for several apps, and improved notifications channel.

Previously, OnePlus' CEO Pete Lau has Tweeted informing users that OnePlus 3 and OnePlus 3T will receive Android 8.0 Oreo update within this year. "OP3/3T will receive Android O within this year," OnePlus confirmed during a Reddit AMA. The announcement by CEO Pete Lau was followed by a blog post by OnePlus' Head of Product Oliver Z, who has claimed that OnePlus 3 and OnePlus 3T smartphones won't receive any Android version update after Android 8.0 Oreo.
