How to Install Pre-Release Android Oreo on the AT&T Samsung Galaxy S7 & S7 Edge

Android Oreo was released many months back, but Samsung has finally approved the official release for the Samsung Galaxy S8/S8+. Recently, a version of Android Oreo for the Exynos Samsung Galaxy S7 Edge was leaked, and can be installed as a custom ROM on our forums. Now, an Android 8.0 build for the AT&T Samsung Galaxy S7/S7 Edge is available.

This is the first release of Android 8.0 for Snapdragon Samsung Galaxy devices, and it brings a bunch of new features and improvements. On top of all the new features that come with Android Oreo such as picture-in-picture mode, notification channels, background app optimizations, notification snoozing, and more, there are also plenty of Samsung-specific changes with Samsung Experience 9.0. This update also contains Samsung’s Bixby.

With Samsung Experience 9.0 comes a new keyboard with stickers and GIFs built in, the App Pair feature from the Samsung Galaxy Note8 which was previously for the S7 Edge only, and much more. The build comes with the latest February security patches so all of the recently disclosed major security vulnerabilities such as BlueBorne, KRACK, and Spectre/Meltdown have fixes in place for them. The update also brings native support for Overlay Manager Service (OMS), the theme engine behind Substratum. Before, the Sungstratum plugin was necessary to apply custom themes, but now you should transition over to the Andromeda plugin which is more stable.

Want to install this update on your AT&T Samsung Galaxy S7 or S7 Edge? Well, you’re in luck, as this update was pulled from the ATT servers and perfectly safe. This update is not a beta, but rather a pre-release build so it might be unstable. Currently, the only way to install this is if you have a Galaxy S7 or S7 Edge on the latest update. There are no Odin builds currently available to flash, unfortunately, so this is the only way. If you feel that this is unstable and you want to uninstall it, you can use this file in Odin for the S7 edge and this for the S7.

How to Install Android Oreo with Samsung Experience 9.0 on the AT&T Samsung Galaxy S7/S7 Edge

Samsung Galaxy S7 Edge (Exynos) receives Android Oreo ROM with Samsung Experience 9.0

Android 8.0 Oreo was released back in August of last year, but it has taken Samsung many months to even begin an official beta program for the update. The beta program was our first introduction to the new Samsung Experience 9.0, but unfortunately, it was limited to the Samsung Galaxy S8/S8+ and unofficially available on the Samsung Galaxy Note8. However, by a stroke of luck, some users in Vietnam (via SamMobile) began receiving the Android Oreo update on their Samsung Galaxy S7 Edge. Thanks to this, any Exynos Samsung Galaxy S7 Edge can now enjoy Android 8.0 Oreo with Samsung Experience 9.0!

Initially, users were rightfully skeptical of the claim that Samsung rolled out Oreo to users in Vietnam. After all, it’s rather easy to fake screenshots, isn’t it? Why would Samsung roll out Oreo to the Galaxy S7 or S7 Edge before rolling it out to its flagship models, the Samsung Galaxy S8/S8+/Note8? Indeed, while these reports seemed fake at first, but we can now confirm their authenticity.

Earlier today, XDA Senior Member Kill-Switch posted a system and kernel dump from this alleged leaked S7 Edge Oreo build. Thanks to this, XDA Senior Member ProtoDeVNan0 was able to quickly put together a ROM that can be flashed on any Samsung Galaxy S7 Edge (Exynos). This ROM is based on the leaked firmware, and it brings Android 8.0 Oreo with Samsung Experience 9.0 to the Galaxy S7 Edge.

If you are a lucky owner of the Samsung Galaxy S7 Edge Exynos model, then you can upgrade unofficially to Android Oreo right now thanks to this ROM! You’ll be able to enjoy Samsung Experience 9.0 before most Samsung Galaxy S8/S8+ owners (excluding those users who followed our guide on manually updating to Oreo). The only requirement is that your bootloader is unlocked (easy for Exynos models) and you have flashed TWRP onto your device.

I will link the TWRP thread that contains detailed instructions on unlocking your bootloader and flashing the custom recovery, as well as the S7 Edge firmware that you can install right now. Please read each thread thoroughly before proceeding with modifying anything on your device!

Android Oreo accidentally lands on Galaxy S7 Edge, here’s a video of it

A video of the Samsung Galaxy S7 Edge running Android Oreo has appeared online. The footage was published yesterday while reports that the update had accidentally been pushed to S7 Edges in the region were coming in. 

Editor's Pick

The update, firmware version G935FXXU2ERB2, appeared just ahead of the Samsung Galaxy S8 Oreo update, and was seemingly an isolated incident. For these reasons, there were suspicions that the story was fake.

The unofficial Samsung Viet Channel (via SamMobile) uploaded the video which appears to prove otherwise. It shows a screen-recording of the S7 Edge running the Experience 9.0 skin as seen in the recent Galaxy S8 Oreo beta, with the same home screen UI, buttons, updated camera app etc. Check it out below.

While we don’t know for sure if this is the exact software that will roll out when Samsung begins its official S7/S7 Edge Oreo deployment, we can assume it represents something very similar to what will be in the final build.

In related news, Android Oreo has started rolling out to Galaxy S8 devices in Germany. The Note 8 rollout should follow soon, before the S7 series is expected to become the new priority.

Galaxy S7, A5, A3 and Tab S3 Android Oreo update reportedly in development

After completing its Android 8.0 Oreo beta for the Galaxy S8, Samsung will now be turning its attention to updating other devices—and we might know which ones. While the Galaxy Note 8 will no doubt be Samsung’s new priority, after that, reports suggest it will work on updating the Galaxy S7 and S7 Edge, Galaxy A5 and A3 (2017), and the Galaxy Tab S3.

The news arrives via Samsung fansites SamMobile and GalaxyClub, who have jointly confirmed the plans. However, we have no clue as to when any of these rollouts will begin. Samsung is yet to deploy the final Oreo software to the Galaxy S8—though it should be happening in the coming weeks—and we haven’t heard about the Galaxy Note 8 update since its test firmware was leaked in December.

While we could be waiting for some months to see all of these updates arrive, at least we have some idea of where Samsung is headed next with its update schedule.

The websites also touched on the status of the Galaxy S6 Oreo update, stating that they have no information to indicate it’s in the works. Giving that the S6 arrived in April 2015, running Android 5.0.2 Lollipop, it would be odd if Samsung did upgrade it to Oreo; manufacturers tend to deliver two major Android updates to their flagships, and the S6 has already received those.

Here’s a list of Samsung Galaxy devices that may receive Android Oreo according to leaked firmware

Android 8.0 Oreo was announced in August of last year. Since then, multiple companies (such as Sony and HTC) have either confirmed which devices will receive the Oreo update, or have started to actually roll out the update (such as OnePlus and Nokia). However, the largest Android smartphone OEM, Samsung, has only rolled out an Android Oreo beta program to its Galaxy S8 and S8+ devices, leaving every other Galaxy device owner in the dark about when to expect the update.

So which Samsung Galaxy devices will actually receive the Android Oreo update? While we don’t have a 100% confirmed list, we have put together a list (thanks to help from XDA Senior Member mweinbach) of devices we believe will receive the update based on a deep dive into the framework files of the leaked Oreo beta for the Samsung Galaxy Note 8 (the latest of which can be found here).

Within the framework-res file of the unreleased Note 8 Android Oreo beta, we found a list of XML files that appear to describe the hardware that is present on certain Samsung devices. Most importantly, the titles of these XML files contain the internal code-names of many current Samsung devices. The existence of these XML files isn’t proof that the devices listed below will receive Oreo since they could be leftover files, however, the fact that several code-names for unreleased Samsung devices are also mentioned suggests to me that Samsung is experimenting with Oreo on these different devices.

Samsung Galaxy Tablets that may get Android Oreo

The only device that seems out of place in this list is the Samsung Galaxy Tab A 8.0 (gt58) which was released in 2015 with Android 5.0 Lollipop. I’m doubtful it will actually receive Oreo, but Samsung could surprise us. It’s also possible that Samsung is merely evaluating an Oreo update for this device, and that such an update will never see the light of day.

Finally, we didn’t see any of the following devices listed in the framework files, but given their release dates and the fact that their sister devices will likely receive the update, we can presume that these Samsung Galaxy devices will also get a taste of Android 8.0 Oreo.

Those are all of the devices that we found in the framework files. Again, this list (save for the 2015 Galaxy Tab A 8.0) lines up pretty closely with the devices you would expect to receive the 8.0 Oreo update. However, nothing is confirmed until Samsung makes a public statement on the matter. Companies can test software releases for any number of devices, but later can them if they decide it won’t run reliably on that device.

We’re sure that many are disappointed, though not surprised, to see that the Samsung Galaxy S6 isn’t on the list. The device is certainly capable of running Android Oreo as evidenced by the numerous unofficial ports on our forums, but whether Samsung wants to invest resources in updating a two and a half year old device is a different story.
