Camera

The dual-camera system on the Note 9 is similar to that of the Note 8 and the S9+, consisting of a 12MP primary wide-angle lens (with the notable addition of a dual-aperture system going from ƒ/1.5- ƒ/2.4 with a 1/2.55-inch sensor and dual-pixel PDAF) and a 12MP ƒ/2.4 telephoto lens capable of 2x optical zoom and 10x digital zoom (with a 1/3.6-inch sensor and AF). Both lenses are optically stabilized. The lenses were arranged horizontally in the camera module on the back of the phone. Like on the S9, the Note 9 supports video recording at

There is also a water carbon heat pipe on the phone as part of the touting towards its gaming capability allowing for longer gaming sessions without thermal throttling.

S Pen

The biggest change to the Note 9 is to the S Pen. The S Pen now has Bluetooth capabilities, including the ability to tap the button on it (hold, single or double) to do certain tasks, such as moving forwards or backwards in presentations or taking photos, and third-party support is provided for apps via an SDK. S Pen Bluetooth capabilities have been removed in the Galaxy S25 Ultra. The S-Pen now has a "battery" (essentially a

) that charges wirelessly when the pen is docked in the silo, with Samsung claiming 30 minutes of usage (or up to 200 clicks of the button) with only 40 seconds of charging.

Software

''Notebookcheck'' stated that the Note 9 had better longevity than contemporaries released in 2018, stating "Unlike most flagship phones from that era, however, the Note 9 still manages to look fresh, while offering premium features and performance, even by today's standards. And that, perhaps, is why it'll go down as the last truly great Android flagship." According to ''Android Police'' in 2025, "If you polled long-time, hardcore Samsung fans, I think they’d choose the Galaxy Note 9 as one of their all-time favorite devices. I know the

It still has a loyal fan base today, as I hear from users on their second batteries and third screens — anything to keep their beloved Note 9 in service". The Note 9 includes a microSD card slot, 3.5mm headphone jack, iris scanner, rear fingerprint sensor, and MST payments, all which are missing in the Galaxy S25 Ultra (Samsung had rebranded the Note as the Ultra starting with the Galaxy S22).
