Quoting the tl;dr in the linked article:
Samsung could be stepping up its game by offering seven years of major Android updates for the Galaxy S24 series, and the generous update policy might extend to other Galaxy flagships.
The Galaxy S24 series might also introduce charges for AI features like Live Translate and Pixel-like photo editing tools after 2025.
There’s speculation that users may need to sign in to their Samsung accounts for certain AI functionalities.
Which Chinese phone does that? They were the first to copy Apple when they removed all that. The only ones that still have card slots and headphone jacks are all the low-end phones, and heck, even those are going away. Xiaomi has been removing the card slots on the higher-end Redmi Notes.
