Samsung Galaxy S25 vs Samsung Galaxy S26 Ultra

Samsung Galaxy S25

The Galaxy S25 retains the same flat-edge design language as its predecessor with minimal visual changes. It's slightly lighter and thinner, but you'd be hard-pressed to tell them apart.

• I swear these are the new phones, even though they look exactly like last year
• Compact form factor remains a rarity in the Android flagship space — fills an important niche
• One of the laziest and most uninteresting flagship families Samsung has ever released from a design perspective

Samsung Galaxy S26 Ultra

The S26 Ultra is the thinnest (7.9mm) and lightest (214g) Ultra ever, ditching the titanium frame in favor of Armor Aluminum. Rounder corners improve the hand feel significantly. Gorilla Glass Armor 2 protects the display. The design change from titanium to aluminum is divisive — some see it as a downgrade, others say it doesn't matter in real use.

• At 7.9mm thin and 214g, this is the thinnest and lightest Galaxy Ultra ever — noticeably more comfortable to hold than the S25 Ultra
• Rounder corners give the S26 Ultra a more comfortable grip — a welcome departure from the sharp-edged Ultra design language of recent years
