After a delay of 2 weeks, OnePlus finally released Indian builds. Scroll down to read more about this (after the changelog section).

2020-09-23 21:02 IST: Added link to OB2 announcement

OnePlus had released the first Developer Preview for Android 11/R earlier this year. It was only available for 8-series devices. They quickly got DP2 on 14th JulyDP3 on 12th August, and DP4 on 31st August.

On 8th September, OOS11 was promoted from Developer Preview to the Open Beta track - right on schedule! Now 8-series devices just got OB2 as well.

We've listed the changelog of both OB1 & OB2 for 8-series, so that users who haven't installed any OOS11 Open Beta build yet (or users who don't have an 8-series device) can see what's new:

We wrote about OxygenOS 11 changes in this article, which is based on DP3 knowledge.

OB2 changelog has something quite interesting:

The Ambient Display "Canvas" feature. Image credit: XDA

With this feature, you can quickly create a wireframe-version of the image you choose, which will be displayed on your lockscreen while Ambient Display is active. We personally love this feature and it certainly makes OnePlus' Ambient Display different from all the other OEM implementations. If you want to learn more about this feature, either install OB2 and play around with it or check these articles:

At this time, only the 8-series devices can install this OB. We will update this article and send notifications again, in case more devices receive OOS11.

If you received a notification about this article and you don't own an 8-series device, we sincerely apologize.

Which devices support OxygenOS 11 OB2?

  • OnePlus 8 (all variants except carrier-branded e.g. TMO/VZW)
  • OnePlus 8 Pro (all variants except carrier-branded e.g. TMO/VZW)

OnePlus did not create regional builds for OB1, but they promised OB2 would have it. However there's still no regional build for OB2, which means Indian users who're installing OB2 on their 8-series devices may experience some features missing (e.g. Red Cable Club etc). While we're offering downloads for all regions, we recommend waiting for future builds if you care about missing India-exclusive features you're already used to.

On 8th October (2 weeks after OB2 was announced), OnePlus finally released Indian builds. We've analyzed the ZIPs and can confirm that there are quite a few India-specific APKs. Whether you call that "features" or "bloatware" is up to you. If you own an Indian variant of 8-series and haven't installed OB2 yet, you can use the app to install OB2 now (instructions below). They should contain all India-specific features like Red Cable Club etc. We're disappointed that they released an India-specific build so late - most people in India have already installed global OB2 by now, and it seems there's no way to install this India-specific build now, as it's an older build (OnePlus doesn't allow installing older builds via Local upgrade). Comparison of build dates:

  • OnePlus 8
    • Global: 2009181221 (18th September 2020 at 12:21)
    • Indian: 2009181216 (18th September 2020 at 12:16)
  • OnePlus 8 Pro
    • Global: 2009181219 (18th September 2020 at 12:19)
    • Indian: 2009181217 (18th September 2020 at 12:17)

You can clearly see that Indian builds are slightly older by a few minutes. So OnePlus basically had Indian builds ready, but claimed builds were delayed "for technical reasons". It's possible that the delays were either due to Google's CTS (Compatibility Test Suite), or an extended QA (Quality Assurance) period.

Other devices (7T-series, 7-series, etc) may get OOS 11 soon in the form of an Open Beta update.

Where can I install OB2?

This is meant only for 8-series devices - it WILL NOT WORK for other devices. Since this is a beta update, make sure to backup all important data before your proceed as it may not be stable!

Before installing, please ensure your battery level is at least 30% and you have at least 3GB space left on your device. If you encounter any bugs in OB2, make sure you report them to OnePlus.

You can install the preview using this app itself (switch to the "Open Beta" update method - you might have to enable "Advanced mode" as well) or by visiting the forum thread listed below:

Can I revert to the stable version of OxygenOS?

Yes, please read the forum thread of your device as linked above for detailed instructions. Rolling back will completely wipe all your data, so please take a backup before proceeding.

Below are the rollback/downgrade packages for each 8-series device. Make sure you choose the correct rollback package for your device and region. We are providing these links purely for your convenience, as rolling back isn't natively supported by our app. After downloading the correct rollback package, move the file from the "Downloads" directory to the topmost directory of internal storage (the same directory that the "Downloads" folder is in). Then, open Settings -> System -> System updates -> cog icon in the top right -> Local Upgrade, and choose the rollback package.

Rollback packages

The following packages will rollback your device to the currently latest Android 10 stable version, and will wipe all your data. These are not the packages you should download if you're looking to update to Android 11/R. For that, close this news article and change your update method to "Open Beta" in the app's settings (if your device is either an OP8 or OP8Pro).

Please take great care in downloading the rollback package meant ONLY for your specific device and region.
