If you're hoping the Galaxy S9 will be a phone that can last for years and years, there's some good news to support that. It's officially been confirmed that Samsung's latest flagship will support Project Treble, which should theoretically make it easier and faster for Samsung to continually push out updates to the device over its life.
Project Treble was announced with Android 8.0 Oreo during Google I/O 2017, and as a refresher, it was a low-level change to how Android works that creates a separation from Android as an OS from the work done by hardware partners like Qualcomm. In practice, that minimizes the amount of work someone like Samsung would have to do to get the latest version of Android to work on their devices.
Of course, if you really stay on top of the nitty-gritty Android news this shouldn't be much of a surprise; Google already said that any device running Android 8.0 Oreo would have to support Project Treble out of the box. Samsung skirted this with the Galaxy S8 which does not support Project Treble after its Oreo update, but all devices going forward should have the compatibility.
So if this was the make-or-break decision for your Galaxy S9 purchase, you can buy with confidence. Just avoid a wireless carrier when you do.
