Every specification here is taken from the manufacturer’s own published figures and checked by a person before it appears. A tick marks the higher figure only where higher is simply better, such as battery life or memory. Not published means the maker does not publish that figure, not that the phone lacks it. Prices are the cheapest we have right now and change as stock moves, so take the price on the product page as the real one.
The verdict
Both launched in 2025. On the specifications Samsung publishes, they share the same refresh rate, chip and RAM. They differ on screen size (6.2in against 6.9in), main camera (50MP against 200MP) and main camera aperture (ƒ/1.8 against ƒ/1.7). 12 other rows on this page differ as well. There is more than price between these two, so it is worth reading down the table before choosing.
