The update was obviously a mistake made by someone at the Samsung development team or related departments, who must have pushed a seemingly finished build of the update. It isn’t possible that Samsung would purposefully release such an update to the S7 before the newer Galaxy S8. Aside from this, Samsung did not even hold a an Oreo Beta trial for S7 edge users.
We don’t know how many people actually managed to download and install the update in Vietnam, but there may be at least one. These screenshots were sent to AndroidU from a dual-SIM, international variant of the Galaxy S7 edge via a public Galaxy S7 edge group chat on Telegram.
The update in question weighed in at about 1.4GB with a build number of G935FXXU2ERB2. See the screenshots below.
We already knew that Samsung was working on the Oreo update for the Galaxy S7, we just didn’t expect to see anyone get it this early. Then again, this isn’t the first time folks have accidentally received a major update far before its public release.
Thanks for the tip!
