It said so on the tin. Sometimes this news make it sound like someone suddenly decided to fuck customers over, but this was the plan all along. Newer, more robust versions and designs are getting more time. Samsung is one of the few Android vendors who actually follow through with their support promises. Even if software updates and OS security updates stop, the phone software itself will continue to receive security updates to the user shell modules like Google Play services for another 6 years. OneUI perhaps for half of that time. The phone will likely continue to work just fine for all that while. It always sucks when there are articles that frame “company did today what they said they were gonna do today, 4 years ago!?” like some sort of gotcha. If you didn’t want in on the deal, that’s on you from 4 years ago. Samsung did exactly what they said they were gonna do with their experimental prototype toy. They have worked out the kinks and newer phones get longer support times now they’re established products.
