The answer to this question is quite simple: Samsung’s Marshmallow update rollout time is less than impressive because it’s very, very slow.
Android 6.0 Marshmallow was first released to certain Nexus gadgets in October 2015. Several manufacturers immediately implemented the new update in their devices while others, like Samsung, were slow to react. Granted, rolling out an update to millions of smartphones and tablets in different countries and regions isn’t exactly a walk in the park, but five months have passed and it still hasn’t been fully rolled out to all Samsung devices around the world. This leaves Samsung fans asking: “Will we ever get the Marshmallow? How long do we have to wait?”
To be fair, dealing with Android updates isn’t always easy for manufacturers since they need to release a high-quality update that would seamlessly blend with their hardware. Samsung, for instance, has to make changes to its TouchWiz UI while working on the Google software, which means it has to double the effort and spend twice more time.
Despite this, Samsung has been able to release Marshmallow updates to several models in certain countries starting this year. In February, for example, it rolled out the update for Samsung Galaxy S6 and S6 Edge in South Korea, India, Iraq, Russia, and the United Kingdom as well as in European countries like Spain, Italy, Germany, Macedonia, Croatia, the Czech Republic, and the Netherlands. Recently, the Samsung Galaxy S6 Android 6.0.1 Marshmallow began appearing in Asia, the Middle East, the United States, and the rest of Europe.
Samsung has also released the Marshmallow update for the Galaxy S5 SM-G900L in South Korea just last week, and many Samsung owners in the country have reported that they have received the update over the air (OTA). With this South Korean release, it’s fair to say that Galaxy S5 Marshmallow update will be made available in other regions soon, although no one can really predict the exact dates.
Several timetables that refer to Samsung Marshmallow release dates have been leaked in the past months. The most recently leaked roadmap showed that a few Samsung devices (such as the Galaxy S5 and the Galaxy A8) will receive their updates on either March or April. It’s important to note that this timetable is just a leak and isn’t exactly an official announcement from Samsung, so the release dates mentioned in the timetable aren’t exactly set in stone.
