It appears that Samsung's Galaxy Note series is officially on the rocks as the company has moved from monthly to quarterly updates for the Note 9.

Samsung’s Galaxy Note 9 smartphone isn’t broken yet, but it does appear to be losing ground. According to Samsung’s official security update list, updates for the Note 9 have officially been scaled back to once per quarter. The device is now three years old and Samsung is really pushing its foldables, so this isn’t much of a surprise.

While this is undoubtedly a planned phaseout, you don't need to throw out your phone just yet. 9to5Google suggests that the Galaxy Note 9 will likely continue to get quarterly updates for the next year, before switching to semi-annual updates after that.

Then, after a year of biannual updates, support will likely end for good. Not ideal if you still have and are using a Galaxy Note 9, but support doesn’t end until 2023 (at the earliest).
