These niche phones never fail to run old versions of Android. This phone runs Android 11, which was released October 4, 2021. Android 13 was released 15 August 2022.
If all the niche phones don't have updates, that's probably a failing of the OS rather than the niche phones.
Somehow, Microsoft manages to get Windows updates out to everywhere and computers in stores end up having the latest OS on there. Google makes Chrome OS devices update. I think there's two or three projects that were supposed to make Android updates actually happen, but where's the pudding?
