nullSamsung made the lenses bigger on the S26 Ultra. In camera terms, that means wider apertures, which means better low-light photos.
The main camera change:
The 200MP primary camera went from f/1.7 to f/1.4. Samsung says it lets in 47% more light. That's a significant improvement.
What does more light mean in practice? Clearer indoor photos. Better evening shots. Less blur because the camera can use faster shutter speeds. Sharper detail in challenging lighting.
The telephoto improvement:
The 5x zoom camera moved from f/3.4 to f/2.9. Samsung claims 37% more light.
This matters because telephoto lenses typically struggle in low light. When you're zooming in at night, the S25 Ultra often struggled. The S26 Ultra handles these situations noticeably better.
What stayed the same:
The ultrawide keeps its f/1.9 aperture, already good. The 3x telephoto stays at f/2.4. Samsung focused improvements where they were needed most.
Why you can't just update your old phone:
Aperture is hardware. It's the physical size of the lens opening. No software update can make your S25 Ultra's f/1.7 lens act like an f/1.4 lens.
Other camera improvements:
Samsung fixed the noise problem S25 Ultra users complained aboutβweird distortion when shooting the sky in low light. New processing algorithms produce cleaner images. The faster Snapdragon 8 Elite Gen 5 means Night mode processes faster too.

If you're still curious about the , here are some other answers you might find interesting:
It depends on which storage size you buy. Samsung ties the RAM amount to the storage configuration, which is a bit annoying if you just want more RAM without paying for a terabyte of storage.
| Storage | RAM | Price | |---------|-----|-------| | 256GB | 12GB | ,299 | | 512GB | 12GB | ,419 | | 1TB | 16GB | ,659 |
Want 16GB of RAM? You're buying the most expensive Galaxy S26 Ultra model.
Probably not. Here's the truth: 12GB is plenty for almost everyone.
You can have a bunch of apps open, switch between them without reloading, play games, browse with dozens of tabsβ12GB handles it all. Android has gotten really good at managing memory, and Samsung's software is optimized for it.
If you do serious creative work on your phoneβediting 4K or 8K video, working with huge photo files in Lightroom, or using DeX as a legitimate desktop replacementβ16GB gives you more headroom. Heavy gamers who keep multiple games and apps running simultaneously might appreciate the extra RAM too.
Some people think Samsung should offer 16GB on all S26 Ultra models at this price point. Other flagship phones are starting to do that. But in day-to-day use, most people won't feel the difference between 12GB and 16GB. It's one of those spec numbers that looks good on paper but rarely translates to real-world benefits for typical users.
Ever watch a video where you can barely hear people talking over the wind or background noise? Audio Eraser is Samsung's solution for that, and on the Galaxy S26 Ultra, it does something pretty clever.
The basic feature has been around, but now it works in real-time on apps like YouTube and Netflix. Watching a video with annoying background noise? The S26 Ultra can filter it out on the fly. The audio gets cleaner while you watch.
The AI listens to different elements in the audioβvoices, music, wind, crowd noiseβand lets you dial down the stuff you don't want. All processing happens right on the phone using the Snapdragon chip's AI capabilities, so nothing gets sent to a server.
Open any video you've recorded in the Gallery app, and you can clean up the audio before sharing. Windy beach video? Kill that wind. Concert recording where the crowd is drowning out the music? Tone them down.
It's not magic. Sometimes when you crank up the noise removal, you'll notice weird audio artifactsβvoices can sound a bit robotic or hollow. And if the sound you want to keep and the sound you want to remove are too similar, the AI struggles.
For casual cleanup though? It works surprisingly well. Just don't expect studio-quality results from a phone feature.
Here's something Samsung doesn't tell you during setup: your fancy new Galaxy S26 Ultra isn't running at full resolution out of the box. They ship it set to FHD+ (basically 1080p) instead of the gorgeous QHD+ (1440p) the screen can actually display.
You paid for a phone with a 6.9-inch screen capable of 3120 x 1440 pixels. That's insanely sharp at around 500 pixels per inch. But Samsung cranks it down to save a bit of battery, and most people never know to change it.
Super easy:
Done.
Definitely. Text looks crisper. Photos show more detail. Apps with small UI elements are easier to read. It's one of those things where you might not realize what you were missing until you turn it on.
This is why Samsung does it. They're trying to squeeze every bit of juice they can. But honestly, for most people the battery impact is minimal. Maybe 5-10% over a full day, if that.
Unlike older Samsung phones, you can use the full 120Hz refresh rate at QHD+ resolution. No compromises.
If you're paying ,299+ for the S26 Ultra, turn on full resolution. Experience what you paid for.
