In the last few hours, some users have found themselves by surprise with a new version of Android on their device. We refer to the presence of Android 7.0 Nougat which apparently is already reaching some Samsung Galaxy S7.
Apparently those with Android 7.0 Nougat are very specific terminals, contrary to what we discussed a few days ago in which we informed you that Samsung would equip its Galaxy S7 and S7 Edge withAndroid 7.1.1 Nougat January 2017.
Android Nougat Security Update
The surprise comes because the arrival of Android 7.0 Nougat to the Samsung Galaxy S7 has not been officially announced. The strangest thing is that it has come “disguised” through the security update of the phone for this month of January.
That is to say, when it should be another security update, the user can be surprised since when checking the information in the phone's settings, they will find that it also included the final version of Android 7.0 Nougat.

Possibly this version of Android, corresponding to build G935FXXU1DPLR and which has reached a very small group of Samsung Galaxy S7 terminals, be used to polish details and catch bugs before officially releasing Android 7.1.1 Nougat, which would be the version to which the Galaxy S7 would update.
You have to keep in mind that new versions of operating systems usually cause problems and it seems that Samsung wants to avoid errors for millions of people, which is why it would have chosen to bring a preliminary version and test it on a small number of people before launching the official one later.
