It has been about a month since Google has had their big announcement of the official rollout of Android 6.0, the latest version of the company's operating system for smartphones and tablets. As most Android users know, the rollout of a new version can be slow when it comes to an entirely new version of Android, so what is the word on the Android 6.0 (also known as Android M or Marshmallow) Release Date for the Samsung Galaxy S6, S5, Note 4, and Note 5 for major US Carriers Verizon, AT&T, Sprint, and T-Mobile.
According to Neurogadget, the Marshmallow update for the Galaxy S6, S5, Note 4, and Note 5 will be "released in phases". With this report, this means that once the OTA update is available for one of these devices, there will be no estimated time of when this update will come to your device, and it depends on your region and carrier.
Speaking of carriers, PC-Tablet reports that Verizon Wireless, AT&T, and Sprint are among the networks that will also get their Android 6.0 update along with the International counterparts. They also suggest that the upgrade will come to the Note 5 and Note 4 by the end of the year, but do not project a release date for the Note Edge or the Note 3. There are doubts whether the Note 3 will be receiving the Marshmallow upgrade, like the older generation flagship Galaxy S4.
The general rule of Android updates is that when the newer version rolls out, the latest devices receive it first. Therefore, the current flagship, the Samsung S6, should be the first to receive it. The same trend happened last year with the rollout of Android 5.0 (also known as Android L or Lollipop).
Following the same trend, this means that the earliest to receive it would be the Samsung Galaxy S6, S6 Edge, Note 4, Note 5, and the S6 Edge+, according to Tech Radar. It stands to reason that older versions of Samsung Galaxy devices, such as the former flagship Galaxy S5 and Galaxy Alpha, might have to wait longer. Also included on the list of devices to be upgraded include the S6 Duos, Note 4 Duos, Note Edge, and Tab A, according to YouMobile.
It would be good if Samsung were to bring Marshmallow to the more recent users by the end of this year, but older ones will probably need to wait until early 2016 for their upgrade. However, Trusted Reviews states that Samsung's Android updates tend to be drawn-out affairs, as the company has to work to tweak its own custom TouchWiz UI on top of new Google software. For this reason, it takes a while for the newest Android version to roll out completely to newer and older models.
