When it comes to major OS updates, Samsung is not the fastest company in supporting its devices. But it always provides decent long-term support, at least for its most important handsets. Samsung Galaxy S7 and S7 Edge were announced in early 2016 with Android Marshmallow out of the box and they have been officially updated to Android Nougat more than a year ago. Now, the two handsets have been certified by Wi-Fi Alliance with Android 8.0 Oreo installed, and this suggests that the final update should be coming soon.
Alongside Samsung Galaxy S7 and S7 Edge, the mid-rangers Samsung Galaxy A3 and A5 (2017) have been certified with Android Oreo as well and they have appeared in the database of WFA with Oreo installed. Usually, when devices get certified by Wi-Fi Alliance with a new OS version, the final update to that version gets released within some weeks at max. So, expect Samsung Galaxy S7, S7 Edge, A3 and A5 2017 to be updated to Android Oreo in the coming weeks. Actually, Android Oreo is already present on some Samsung devices such as Samsung Galaxy S8 and Galaxy A8.
The operating system is customized by Samsung Experience 9.0, the latest version of the Samsung custom user interface. Samsung Experience 9.0 contains several improvements and new features which were not present in the previous version. Among the most important features added, there are 4 new keyboard modes and a toolbar with shortcuts which can help you to find emojis, stickers, and animated GIFs. Further, there are hundreds of new emojis, GIFs, and stickers available. The keyboard settings menu has been simplified, and the main screen of Bixby virtual assistant has been improved with new cards and options. Among these options, there are background music reproduction and colors matching the actual weather in the user location.
