Samsung is not known for providing timely updates to their devices, not even the flagships. So perhaps users of the Galaxy S7/S7 Edge would have to be grateful that Samsung finally released the Android 8.0 Oreo update for the devices in May 2018. Android 8.0 Oreo was originally released by Google in August 2017. Samsung rolls out the updates by CSC (Country Specific Code). Thus, depending on where you live, you either get the update right away or have to wait. The waiting can be as long as days or even months. However, if you don’t want to wait, you can install the official Android Oreo update manually. Keep in mind the update we’re talking about here is for the Samsung Galaxy S7 and S7 Edge Exynos variants. Follow the steps provided below to install Android Oreo firmware on Galaxy S7 and S7 Edge (Exynos).
The update brought a bunch of new features including all the Android Oreo goodness. These features include picture-in-picture mode, notification channels, background app optimizations, notification snoozing, etc. There are also plenty of Samsung specific changes which come as a part of Samsung Experience 9.0. One of the major features you’ll love or not care about at all is Bixby, which is here now for the Galaxy S7/S7 Edge with this update. There’s a new keyboard with stickers and GIF support as well as the App pair feature from the Galaxy Note 8.
Since this is an Android Oreo update, there’s native support for the Overlay Manager Service. In other words, you can use Substratum themes, which you could also use earlier on Samsung devices. The difference is that you can now use the more stable Andromeda plugin instead of Sungstratum.
- Perform a complete backup of your personal data, including the storage. If you have TWRP installed, you may as well perform a full NANDroid backup from the recovery and/or a Titanium Backup backup if your device is rooted. We’ve already put up guides on using Titanium Backup if you’re interested. We also have some other backup guides which aren’t as wholistic but if you’re not looking to pay for the full version of Titanium Backup, these might be helpful.
