The only thing that really moves on a modern smartphone these days are the mute switch, the lock button, a volume control and, if you're lucky, a dedicated button for Bixby.
So, it is natural that we are curious to see how the new dual opening of the Samsung Galaxy S9 works. Luckily for us, the mandatory disassembly of the iFixit phone includes a pair of close-ups of the opening in action.
As iFixit points out, the opening of a normal camera is controlled by several aperture blades, which are designed to maintain the hole through which the light (that's all an aperture) passes approximately circular. The S9, however, does so with only two blades, since the opening only has two configurations, f / 1.5 and f / 2.4; two blades were apparently enough.
Here is a fancy sliding widget, built from two iFixit photos of the S9 Plus, so you can have the virtual opening adjustment experience:

Still not sold on this phone? Check your local Best Buy. The Samsung section in the New York store that I just visited had a giant opening demo. I think it was built in cardboard, but that does not mean it can not be educational. The adjustable aperture may not be enough to save Samsung in the wars of phone cameras, but it's certainly an excellent conversation topic.
And, of course, be sure to check the rest of the disassembly of iFixit. In general, the S9 does not work well on reparability. It is built with very modular components, but the phone is difficult to disarm without breaking it, and the battery is difficult to change. But that opening, however!
Here is the video disassembly of iFixit from the regular S9:
