After a series of Beta releases and constant testing, Samsung finally started rolling out Android Oreo-based Samsung Experience 9.0 for the Galaxy S8 and Galaxy S8 Plus. The beta program ran for months for both the devices and focused on refinements before the final rollout took place. The OTA was unfortunately called off due to unexpected reboots caused after updating. The majority of users facing this issue had updated their device over-the-air.

After about two weeks later the company has resumed the release as users started to receive the OTA notifications. Since the update is incremental, it will be pushed to a few regions initially and will later expand on to others in the coming weeks. If you haven’t had the chance to update yet, then follow the steps below to install Galaxy S8 and S8 Plus Android Oreo update manually.

Since the new software is based on Android 8.0 Oreo, it offers all the standard Oreo features like Notification Channels, Autofill Framework, Picture-in-Picture mode, faster boot time, and more. On the OEM end, the all-new Samsung Experience 9.0 offers a series of its own exclusive features as listed below.

The app finder window is now revamped and displays smart results for the keywords you enter. Samsung has also included a new Color Lens feature to shift display modes and prevent eye-strain. The new keyboard offers a customizable toolbar, which means you can easily control which features you want up there. Phone’s settings have been simplified. For those who want to use multiple messenger accounts simultaneously, the “Dual Messenger” feature has been introduced. A new permission monitoring section is present as well to effectively control background apps.

That’s quite a lot for the Oreo update itself. Before you head down over to the instructions and install Galaxy S8 and Galaxy S8 Plus Android Oreo update, let us take a quick sweep of the changes that the new CRB7 build will bring to your phone(s). According to the OTA screenshot, the new OTA update is around 530 MB in size. Which means it is bringing a considerable amount of changes to the system. Allegedly, the dreaded issue related to unanticipated reboots should now be fixed. If you’re running the previous CRAP build, you wouldn’t notice much difference at all.

Now, if you have already tried installing the Galaxy S8/S8 Plus Android Oreo update manually via regular Odin, you would have failed. The Odin program will probably halt down at the file-selection window. Well, there’s a solid reason behind this behavior. Samsung has implemented a new compression method for the Oreo firmware. The new firmware files are packed in .lz4 format. The Odin Flash Tool has finally been updated to v3.13.1 that supports the compressed binaries (lz4).
