From Samsung Brazil comes a hint that Android Oreo will soon run the International Galaxy S8/S8+
The International Samsung Galaxy S8 might soon receive Android Oreo
This could mean that the unlocked International variants of the Galaxy S8 and Galaxy S8+ (SM-G950FD and SM-G955FD, respectively) will soon offer features like Notification Dots, allowing users to see at a glance if they missed any notifications. A long press on an app icon sporting the dot, will open a menu showing missed notifications. And don't forget adaptive icons, which allows you to choose between different shapes for the icons displayed on your handset. The choices include Squircle, Rounded Square, Square and Teardrop.
