Camera's 2x Button is a digital zoom, not an optical zoom

[airibis]

The 2x button is not actually switching cameras, it is just preforming a digital zoom on the wide camera.
I placed a piece of electrical tape over the long range lens, in 1x I can see clearly, in 2x I can see clearly (but digitally zoomed in)
Only in Live Focus is the camera blocked by the electrical tape.

So my question is, is Live Focus the only way to use the second camera?
Seems like a waste of a second camera. This is not how it was handled on other dual camera phones, what gives Samsung?

And as per Slashgear: Instead, just as we’ve seen on the iPhone 7 Plus, Samsung mixes together the data from the wide-angle and telephoto lenses on the Note 8 to give the effect of a zoom. The result is the equivalent of 2x optical zoom, completely lossless, as well as a 10x digital zoom.

Going from 1x to 2x is an optical zoom on the wide angel camera, not digital. Beyond 2x is digital zoom.
Nowhere did Samsung claim that going from 1x to 2x was done by switching cameras.

They insist the 2x button triggers the other camera.

The Cnet reviewer is mistaken on the 1x to 2x camera switching.
As stated above, the test is pretty simple to figure out which lens is being used.
