The Android 7.1 update for the Samsung Galaxy S8 and S8+ flagship smartphones is likely to arrive anytime now. Vodafone Australia has provided a heads-up on its website that the update has been submitted for review, which is the last stage before the roll out begins. So in all likeliness, other key markets should also get the update sooner than later. Sadly, there's currently no information on the exact roll out time-frame, but we'll let you know as and when that happens or more details emerge. Source | Via
