Again you fail to understand the point. That line does not tell you it is 1" corner to corner, it's there to tell you that it is a 1" sensor.Not the way it's shown with diagonal lines corner to corner. Maybe this version more clearly indicates what they are telling consumers.
Pretty clear here with the arrows clear at the ends of the lines.
I know it but don’t care. It’s the results that matter not the specs.
I believe that most of the listed phones, by "optical zoom" they mean whatever x compared to the main wide angle lens and don't actually have a lens that can change focal lengths.
They use the phrase "optical zoom" to refer to the cropped FoV relative to the main camera, not a zoom lens. This is standard practice in the smartphone world, and often causes confusion among photographers. It started as a way to differentiate from advertisements claiming "2x digital zoom" or similar, and as you know digital zoom does not make a zoom lens either.
The list of phones with cameras offering true "optical zoom" capabilities by the movement the elements of a lens in front of a sensor is extremely short.
As a matter of fact, my Asus Zenfone zoom (ZX551ML), an early 3G phone released in 2015, already used a 3x Hoya optical zoom lens in periscopic design:

I don't think that article is true (the first one to have an optical zoom lens). My 8 years old Asus Zenfone zoom already had a 3x optical zoom lens (in periscopic design) from Hoya. Just it is not a very popular brand in the world making and Asus itself has never marketing its phone product well as its computer product therefore not many people aware of it.
The article doesn't say it was "the first one to have an optical zoom lens", it says it was “the world’s first optical zoom* 85mm-125mm on a smartphone”.
Oop then it makes sense.
I'm pretty sure he, like the rest of us, knows that a 1" sensor is about only 0.62" corner to corner diagonally.
You bet... that's how the marketing people justify their jobs.Oop then it makes sense.
We can expect many more World's first optical zoom for smartphone, says 24-70, 35-105 or 100-300....
I'm pretty sure that the marketing material in question implies nothing more than some marketing exec or artist not knowing how old vidcon tube sizes related to modern imaging, combined with working in a country that uses metric measurements.
What you "believe" the phone companies "mean" is irrelevant. What will hold up in court when the things get to false advertising charges is what matters, and that is based entirely on "standards of the community", in short "how does a photographer define an 'optical zoom'?" Not an advertiser, a photographer.
I'm almost certain you are. Your arguments are literally not making any sense to me.
You can "believe" whatever you wish to believe, or you can look at the images of the print ads that state exactly what I said they do.
Nope.
Again, no. Did you notice elsewhere where someone posted the mechanism of a smart phone from over a decade ago with an optical zoom lens.
How do you "differentiate" by claiming that the same thing is different.
Yep. Which only means your claims won't hold in court.
Bingo. People aren't describing "the sony phones as the only phones with true zoom lenses", so by your logic, your points are groundless. It's a classic "If A then B" fallacy, because A is not true, therefore you can't say anything about B.
Why?
In that case, every phone in the world that shifted between two cameras would be advertising "optical zoom".
