Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy Note9 should be supported until around August 2021. Buying it today still gets you about -4.8 years of safe use (Apple's written legal minimum is 5 years).

Our verdict

The Note that introduced the Bluetooth S Pen and a big 4000mAh battery — beloved in its day, but fully out of support since 2021.

Pros

  • First S Pen with Bluetooth remote-control tricks
  • Large 4000mAh battery, headphone jack, and microSD support
  • Variable-aperture 12MP camera that was top-tier for 2018

Cons

  • Security updates ended around 2021 — well out of support
  • Stuck on Android 10 with no path forward
Best for: Collectors or S Pen fans wanting a cheap classic NoteBest for: Users who still want a headphone jack and expandable storageAvoid if: You need a secure, supported daily phoneAvoid if: You want modern app and OS compatibility

Frequently asked questions

How long will the Galaxy Note9 get updates?

The Note9 launched on Android 8.1 and received about 2 OS upgrades (to Android 10) and roughly 3 years of security patches, which ended around 2021. It receives no further updates.

What was special about the Galaxy Note9 S Pen?

It was the first S Pen with Bluetooth Low Energy, letting it act as a remote to trigger the camera shutter, control slideshows, and skip music tracks.

Is the Galaxy Note9 safe to use in 2026?

Not for sensitive tasks. With no security patches since 2021, it carries known unpatched vulnerabilities and should only be used as an offline or secondary device.
