Sadly and unfortunately, the 2017 flagship device from Samsung, the Galaxy S8 and S8+, are still running on Android 7.0 and not on 7.1.1. The Samsung Galaxy S8 and S8+ users, and even S7 users have been waiting for the 7.1.1 update from Samsung for some time now.
While Android 7.2 is the latest build of Nougat, it brings minor improvements, whereas Android 7.1.1, an incremental update brings many new features such as Daydream support and other features.
On the brighter side, looks like Samsung will release the Android 7.1.1 update soon for Samsung Galaxy S8 and S7. Now, why do we say that? Well, Samsung has released a new device in China that goes by the moniker Samsung Galaxy J3 2017. The device comes pre-installed with Android 7.1.1. You can download the Android 7.1.1 firmware for Galaxy J3 2017 with build number J3308ZMU1AQG3 from here.
So far, the latest in software from Samsung was Android 7.0. Now, that there is an Android 7.1.1 device from Samsung out there, the 7.1.1 build is surely ready, and the update could be rolling out for the Galaxy S8 units pretty soon, followed by S7.
Meanwhile, while Samsung users are still waiting for Android 7.1.1, Google is set to release the latest Android OS version, Android O in August. Android O will bring new features such as smart text selection, snooze notifications, improved battery life among other important features.
