This is a phased roll-out, as now it is only being rolled out in the UK. Folks at SamMobile report that alongside the update for unlocked Galaxy S7 users, the Android Oreo update available for Vodafone UK-locked Galaxy S7 and Galaxy S7 Edge units.
The software update is also only available over-the-air as of now, but should soon be available for download via Samsung SmartSwitch as well.
If you're not seeing the OS update on your Galaxy S7, keep checking back over the next few weeks. It comes installed with the April Android Security patch and is about 1.2GB in size. The update will bring not only the latest version of Android but some new features to the phone. After several beta versions and months of testing, the final public build is now out. Verizon customers in the USA and all other GS7 and GS7 edge owners around the world shouldn't have to wait too long for the update to reach them now as the global rollout will surely follow. It's an update to the Android 8.0-based EMUI 8.0, which is a tad disappointing, as you'd expect a heavily marketed device like the Honor 7X to be receiving Android 8.1 by now. However, some users have reported that they never did get the update even after signing up, although that seems to be an occurrence in most beta programs.
Unfortunately for owners outside of the United Kingdom, there is no word on when Android 8.0 Oreo will begin rolling out to other regions.
Do you use a Galaxy S7 or Galaxy S7 edge as your daily driver?
