No, I found what it did. . . now I am asking you what more DOES it do. What the website shows it does is nothing much more than what you can do with your finger on the screen. That deserves mocking.
That is NOT true about what you were mocking which does things you cannot do with your finger on the screen. YOU mocked something you had no clue about. . . you just started in without knowing anything about the product, not even it's correct name.
I am asking you to educate me about what your Samsung stylus will do that is not in the instructions provided by Samsung. Frankly, I can see no practical purpose for the button. It's a gimmick.
That's fairly representative of a lot of the gadgets and other additions Android phones and tablets have added to their functions. They are gimmicks some engineering geek says "Hey, that'd be cool to add" and they add it, with out thinking it through as to what real functionality it might have.
My favorite example of such useless gimmicks is that some Samsung phones have Blood Oximeter sensors in them. . . I work in the medical field and not one single doctor that I have talked to can think of a situation where a phone mounted blood oximeter sensor would be useful or even accurate for any medical purpose. Another is that Samsung mounted Atmospheric Hygrometers in some of their phones. Totally useless when measuring the water in the atmosphere when they've been carried within several feet of the water exuding human body.
The question arises that just because you can add something to the spec list, SHOULD you? Steve Jobs took the view that perfection comes from what you can take OUT.
Is it true that he said "If you see a stylus, they blew it." back in 2010?
Pathetic. More misdirection so you can keep shilling for Apple.
You are a joke of a man.
