Considering that Android 7.0 (also known as Android N or Nougat) is coming soon, there has been a lot of talk about what it will do for newer Android devices like those from Samsung. However, there still hasn't been Android Marshmallow (also known as Android 6.0 or Android M) coming to more recent Samsung Android phones. This is the latest news of 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, AT&T, US Cellular, T-Mobile, and Sprint.
With the popular Samsung Galaxy S7 arriving with Marshmallow within its packaging, it was pretty clear that all the smartphones down the line were going to get it. So far, the older models of the Galaxy S6, Galaxy S6 Edge, and Galaxy Note Edge are pretty much taken care of. Even the Galaxy S6 Active is getting its update now, according to Tech Radar.
With the Galaxy S5, there are reports for Marshmallow being available on Sprint, T-Mobile, and Verizon. The signs don't seem good for AT&T, as there doesn't seem to be any sign of when that is coming.
Fortunately, things are looking very good when it comes to phablets. Most of the subscribers for the Note 5 should have the upgrade, and it sounds like the Note 4 will get their upgrade on subscribers like Sprint, U.S. Cellular, Verizon, and now T-Mobile.
There was a definite surprise when it came to the Note 3. It wasn't really believed that this older phablet from Samsung would be getting the Android update, but a report from Neurogadget revealed that it has received a surprise upgrade to Marshmallow. The issue is that it isn't an Over The Air (OTA) event from any carrier, but this is a custom ROM that requires a little bit of know how to install, but instructions are available at the link to the article here.
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.
There is a report from PC Advisor stating that Android Nougat could be available in September and come straight to 2016 Nexus phones. As for when it will comes to Samsung, there is much speculated that Android N will officially roll out onto Samsung devices at the first quarter of 2017. This is just following the pattern of the release of Android M from last year.
