According to Rahman’s findings, code exists on Android 14 that enables the distinction of different buttons on a stylus. These buttons include the primary button located closest to the tip, the secondary button, the tertiary button, and the tail button. The tail button is what some USI styli, such as the Penoval brand, use as an eraser tool. However, it looks like the tail button functionality will now be launch the note-taking application of your choice.
This makes perfect sense considering that we already have USI styli available for sale right away, while a proprietary pen for the Pixel Tablet wouldn’t necessarily be available right at launch. This does not mean that Google won’t try to launch its own branded Pixel Tablet stylus sometime in the future, as it was rumored before the official announcement for the tablet took place.
