Well, it seems like most of the newer Android devices 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.
Samsung is pretty good at getting the latest version of Android to its devices. After all, the flagship series of the S7 and S7 Edge already came with Marshmallow right out of the box. Then, when it comes last year's Samsung Galaxy S6, it came out for all five carriers, and this goes for the Galaxy S6 Edge. As far as the S6 Edge Plus is concerned, it has come to AT&T, and then it should come to every carriers. So what about the Galaxy S5? It should be available for Sprint, T-Mobile, and Verizon. Any flagships lower than that are not going to get it.
So, what about Samsung phablets? Well, it came to Verizon, Sprint, T-Mobile, and AT&T for the Samsung Note 5. The word on Tech Radar is that the upgrade has come to the Galaxy Note Edge in most regions. According to the Nashville Chatter Class, T-Mobile rolled out the Galaxy Note 4 Marshmallow update toward the end of last month, and it is one of the last among the four major American carriers to bring the firmware.
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.
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.
