OnePlus 15 vs Galaxy S25 Ultra: Sample Photos Comparison

The OnePlus 15 is here and it has to answer one big question that comes up every year: is the camera finally good enough?

This year, OnePlus switches the established round camera style for a new rectangular camera island on the back. It loses a bit of its signature styling for a more generic look, but after all, it's the image quality that matters.

And this year, image quality also changes quite a bit. OnePlus cuts the ties with long-time partner Hasselblad with the 15 series, but surprisingly... this might not be a bad thing after all.

So how does the OnePlus 15 compare to the one phone most Android fans talk about, the Galaxy S25 Ultra?

$999 ⁹⁹

The powerful OnePlus 15 can now be yours with two gifts worth up to $200 at the official store. OnePlus.com pairs the flagship phone with a free SUPERVOOC cable (USB-C to USB-C) and an optional gift, which includes a magnetic charger, a magnetic power bank, and the OnePlus Buds Pro 3. You can save extra with a trade-in.

The 50-megapixel main camera on the OnePlus 15 still uses a slightly smaller sensor than the one on the Galaxy and you still lack a secondary telephoto camera like you have on the Samsung flagship. But on the flip side, the 3.5X telephoto camera on the OnePlus actually has a bigger sensor than the 3X camera on the Galaxy, and the ultra-wide setup is quite similar across these two.

Let's see if all of that means photos will look worse on the OnePlus, or if it can make up for that with good processing.
