Available in Phantom Black, Titanium Gray, and Emerald Green, the S25 Ultra feels like a device built for executives and creatives alike.
On the other hand, the OnePlus 13 Pro opts for a more curved and ergonomic design, with a ceramic back and polished metal frame that feels luxurious in hand. It’s slightly lighter than the S25 Ultra, making it more comfortable for prolonged use. The camera module is seamlessly integrated into the rear panel, giving it a minimalist yet futuristic look.
