The comprehensive Android Oreo device update list
UPDATE 20/9/17: Motorola
Android O was released on August 21 and with that out of the way, we can focus on the race between OEMs to see which ones push updates out faster.
Oreo, as a major update, brings a slew of significant improvements, most notably in the UX, UI, and security departments. Other functionalities like improved Bluetooth connectivity and audio processing are extras on top of what is already an incredible package.
As usual, the bigger OEMs will be the first to get updates, with Google paying attention to its own Nexus and Pixel lines. "We're pushing the sources to Android Open Source Project (AOSP) for everyone to access today. Pixel and Nexus 5X/6P builds have entered carrier testing, and we expect to start rolling out in phases soon, alongside Pixel C and Nexus Player," the proprietors of the Android OS said on their official blog. "We’ve also been working closely with our partners, and by the end of this year, hardware makers including Essential, General Mobile, HMD Global Home of Nokia Phones, Huawei, HTC, Kyocera, LG, Motorola, Samsung, Sharp, and Sony are scheduled to launch or upgrade devices to Android 8.0 Oreo. Any devices enrolled in the Android Beta Program will also receive this final version. You can learn more at android.com/oreo."
At the moment, only users of devices in the Nexus and Pixel lines have access, as OTA updates rolled out over the past few weeks. Those yet to get OTA updates can flash the update manually with the files here—at the cost of their data, of course.
Samsung has been mostly silent on the issue, which is to be expected, really, as its Galaxy S8 is still yet to get an update to Android 7.1 Nougat. The newly released Note 8 runs on Android 7.1.1 Nougat, though, so updates for other devices won't be so far off, we expect. There are rumors, however, that the OEM is working on the Oreo update for the S8 and S8+. While there's no concrete information at the moment, Samsung tends to release major updates for two years, so devices released from the tail end of 2015 onwards should have hopes of receiving Oreo.

Alongside Motorola, Sony has a great reputation of releasing timely updates, with the OEM reportedly sending out updates within weeks of the Nougat launch last year. This year may not be as impressive as the last one but users of recently released Sony devices can expect Oreo on their devices in the near future. This includes devices like the Xperia XZ Premium, Xperia XZ, Xperia XZS, Xperia XA1, Xperia XA1 Ultra, Xperia XA1 Touch, Xperia X, Xperia X Performance, and Xperia X Compact. The Z3, Z3+, Z5, XA, and XA Ultra are examples of devices that will not receive the update.
The Nokia 8 was touted to release with Oreo on board in what would have been a nigh-poetic move (Eight on Eight) but the Nokia flagship ended up being launched before the Android package. There aren't a lot of Nokia devices out at the moment, with HMD Global having only the Nokia 3, 5, 6, and 8 to its name. This makes updates a much easier task, with all devices expected to get the upgrade to Oreo. There's already word of Oreo being tested on the Nokia 8, so it won't be long before users get it.
OnePlus released the OnePlus 5 a few months ago, and the OEM has promised that the device will get the Oreo update, with users in the OnePlus 3 closed Beta Program already receiving the 800mb+ Oreo update. Both the OnePlus 3 and OnePlus 3T will receive Oreo, although that will be the last major update they receive, with the OEM reducing updates to simple security patches after that. The OnePlus 2 and OnePlus X will not get Oreo.
Update 18/9/17: Motorola has released its official roadmap for Android Oreo. According to the press release, the devices to receive Oreo updates are the Moto Z, Moto Z Droid, Moto Z Force Droid, Moto Z Play, Moto Z Play Droid, Moto Z2 Play, Moto Z2 Force Edition, Moto X4, Moto G5, Moto G5 Plus, Moto G5S, and Moto G5S Plus. The G4, G4 Plus, E4, E4 Plus, C, and C Plus all miss out, sadly.
Update 20/9/2017: Motorola has confirmed that the G4 Plus will, in fact, be getting Oreo.
Huawei devices run on the OEM's own EMUI skin, so specific information on software release roadmaps aren't an exact science. The OEM has reportedly claimed that its Honor 8 Pro and Honor 6X will receive Oreo, though. We also expect all midrange and flagship devices released from 2016 onwards to get updates to Oreo. This includes devices like the Honor 8, Honor 8 Lite, Huawei P9, Huawei P9 Plus, Huawei P9 Lite, Huawei P10, Huawei P10 Lite, Huawei P10 Plus, and the Huawei Mate 9.
Asus, at the unveiling of the Zenfone 4 series a few weeks ago, announced that devices in the Zenfone 3 and 4 series are going to get the Oreo update.
We'll be sure to keep this list updated with new information and official confirmations.
