So, what can be expected of new Android devices? Well, it seems like most of them have the upgrade to Android 6.0 (also known as Android M or Marshmallow), and Samsung is one of them. Now, there is Android 7.0 (also known as Android N or Nougat) coming, and this is the latest news about Android M Version 6.0 Marshmallow and Android Nougat Release Date for Samsung Galaxy S6, S6 Edge, S6 Edge +, Note 5, Note 4, Note 3, and S5 on Verizon, US Cellular, AT&T, T-Mobile, and Sprint.
So far, Samsung has its Marshmallow situation well in hand, according to Gotta Be Mobile. With the new flagship of the Samsung S7 and Galaxy S7 Edge, it comes with the new version of the operating system right out of the box. This leaves the question of last year's Samsung Galaxy S6, and it came out for Sprint, Verizon, T-Mobile, US Cellular, and AT&T. This goes for the Samsung Galaxy S6 Edge, and there is the S6 Edge Plus, which has come for AT&T, and should come for everything.
So what about the flagship from two years ago with the Galaxy S5? Well, it should be available for Sprint, T-Mobile, and Verizon. Any flagships lower than that are not going to get it.
Now, it is time to talk about the phablet community. Well, it came to Verizon, Sprint, T-Mobile, and AT&T. As for the last year's model with the Note 4, it should be on Sprint, US Cellular, Verizon, and T-Mobile. The word on Tech Radar is that the upgrade has come to the Galaxy Note Edge in most regions.
As for the newest version of Android, Nougat, there is a report that it could be coming to Samsung phones as early as...next month? This report from PC-Tablet should be taken with a grain of salt, as it seems highly unlikely that it would come out this fast. Samsung is a champion for Android, but even its latest flagships didn't receive Android Marshmallow until earlier in the year. This probably means that Nougat won't be coming to the Samsung S7 and other contemporary flagships until early 2017.
If you own a "newer" Samsung devices are encouraged to check your "Settings" and "System Updates" to see if Marshmallow is ready to download OTA. This upgrade might not be ready depending on your U.S. carrier, as it has been shown that certain carriers receive the Android upgrade before others, with no real pattern.
