Typically, Android handset makers promise at least two years worth of major Android updates for their phones. Anything after that is pretty much up to the company if they want to continue supporting the device with additional updates. This is why it sounded like great news when it was suggested that both the Samsung Galaxy S8 and Note 8 could be on the receiving end of Android 10.
Both phones received their Android 9.0 Pie updates back in 2019 and according to erroneous statements made by Samsung reps (apparently on multiple occasions), they stated that both these phones could be updated to Android 10. It has since been confirmed by SamMobile, who spoke to Samsung at the company’s Unpacked event, that this is simply not true.
Like we said, handset makers usually release at least two major Android updates, and Samsung has lived up to their promise with the Galaxy S8 and Note 8. To receive Android 10 would have been a nice bonus, but if you were holding your breath for the update, it looks like you can start breathing again.
That being said, it should be noted that while both devices will no longer receive major Android updates, they are still very much eligible for security updates that will patch bugs and vulnerabilities, so you can safely continue to use either handset for a while more.
