Galaxy S25 Ultra vs Galaxy S24 Ultra
Let’s compare the S25 Ultra with last year’s S24 Ultra:
| Feature | S24 Ultra | S25 Ultra |
| Display | 6.8” AMOLED | 6.9” AMOLED, brighter |
| Body | Square corners | Rounded design, easier to hold |
| Chip | Snapdragon Gen 3 | Faster Gen 3 Elite |
| Main Camera | 200 MP | Same but with better software |
| Ultra-wide | 12 MP | Upgraded to 50 MP |
| Zoom Camera | 10x | Changed to 5x, but better quality |
