The news from the recent days shows that the Galaxy Note 9 stylus will probably be the most practical stylus made by the company so far.
The Wacom-built S Pen isn't exactly like Wacom's stylus for other tablets. Although it uses the same pressure-sensitive nib, its buttons are not the same as other functions, it's not familiar to users. The 'right click' is a shortcut button that calls up Air Command.
The latest exposure shows that there are many more features besides this feature. In addition to the usual digital features, the S Pen will also work as a Bluetooth accessory. This means that the button above can act as a remote controller. In fact, it has been reported earlier that this button can be used for camera remote shutter control, and now it is very likely to add control over functions such as music playback.
Although the idea of a mobile phone with a remote controller sounds really appealing, as to how its usability is currently unverifiable, it depends on the user's own imagination.
