Wait If You Want the Best Software Support
If you plan on keeping your next phone for several years, you might consider holding out for the Galaxy Note 9.
Samsung didn't advertise this on stage during the Galaxy S9 launch event (and it probably won't talk about it during the Galaxy Note 9 launch either), but these devices should receive at least two years of major Android OS upgrades and several more years of bug fixes and patches.
While you might be tempted to skip the Galaxy Note 9 and go with a cheaper alternative like the Galaxy Note 8, Galaxy S8 or Galaxy S7, their software support will come to an end much faster than the Galaxy Note 9's.
The Samsung Galaxy Note 9's hardware upgrades ensures the device will get feature-rich versions of Samsung's upgrades for several years to come.
Samsung's Android updates for older phones are often limited by their aging hardware.
We expect the Galaxy Note 9 to benefit from software upgrades to Android and Samsung's Experience user interface. We expect some carry-over from the Galaxy S9's software, and it will likely have some exclusive features of its own. Again, Samsung is reportedly hard at work on upgrades to the Note's S Pen stylus.
Samsung appears to be testing Android 8.1, a newer version of Android Oreo, on the Galaxy Note 9. Last year, the Galaxy Note 8 launched with Android 7.1.1 Nougat.
The company is reportedly developing a new Samsung Experience 9.5 UI on top of Google's Android 8.1 Oreo update.
Specifically, Samsung is supposedly working on tweaks to the software that could make the Experience UI less intensive on the Galaxy Note 9. This in turn could make the device's software experience smoother.
According to mobile leaker Ice Universe, the Galaxy Note 9's "UX design and interactive experience are worth the wait." This implies that there will be some key upgrades to the company's user interface.
If you plan on keeping your next phone for several years and you think you might want the latest features, fixes, and patches without having to install custom software, think about waiting for the Samsung Galaxy Note 9 launch.
