I recently updated my Samsung S6. As far as I can tell, because I'm now seeing rounded app icons, I'm now using Android 7 with the Samsung Experience UX, based on this post:

How can I confirm the Android version without installing a helper app that does this? There's no settings > about phone and I'm not seeing it under settings > about device, or settings > developer options
