The Samsung Galaxy S26 Ultra from Samsung is a phone that really strikes me as one of the best models you can buy today. I'm using the 12GB RAM and 256GB storage version in black and the first impression was great - the phone looks very sleek and feels really premium. The large display is one of the biggest advantages in my opinion. The picture is beautifully sharp, colours are vibrant and the high refresh rate makes everything run smoothly - whether you're scrolling through social networks, playing games or watching videos. Watching movies or YouTube on such a large display is really enjoyable. In terms of performance, the phone is really fast. Thanks to 12 GB of RAM, it handles multiple apps at once without any problems, and even with more demanding games I didn't notice any lag. Everything runs smoothly and quickly, so using the phone is very convenient. The camera is another big plus. Photos are very detailed and sharp, even in low light. I also like the zoom, which allows you to zoom in on distant subjects without much loss of quality. If someone likes to take photos with a mobile phone, this phone will not disappoint. The battery lasts about a full day of normal use, which is sufficient in my opinion. With less demanding use, it can last even longer. I also appreciate the fast charging, so that when the battery runs out, the phone recharges fairly quickly. Overall, I would say that the Samsung Galaxy S26 Ultra is a great phone for people who want performance, a quality camera, and a big beautiful display. The only drawback is the higher price, but for such a well-equipped flagship phone, it's quite expected. If someone is looking for a high-end smartphone for a few years ahead, I think this is a very good choice.

I've switched from the Samsung S23 Ultra to the new Galaxy S26 Ultra and the difference is noticeable, especially in the details that take the use further. The size of the phone stayed virtually the same, so I didn't have to get used to the new grip. The biggest change for me is the new Privacy Display technology - it really works and the display is much harder to read from an angle in public, which I appreciate. The brightness of the display is excellent and sunlight readability is a level better than the S23 Ultra.
The battery life pleasantly surprised me - in my normal use, the phone lasts two days on a single charge without any problems, and the faster charging is noticeable. Overall, the phone is fast, smooth and feels premium.
The negative for me is the change in the roundness of the corners, which I had to get used to, and also that the battery capacity remained the same as the previous generation. Another small thing is that the camera modules protrude from the body of the phone a little more than in the S23 Ultra, so the phone "wobbles" more on the table if you tap on it. It is not a major problem, but it is noticeable.
Despite these minor issues, I rate the S26 Ultra as a very good upgrade that makes sense.
The size has remained relatively the same
New Privacy display technology
Brightness, sunlight legibility
Lasts during the day - lasts 2 days on a single charge, charging is faster

I'm very pleased with this smartphone. It's very fast and doesn't overheat when gaming (I played Honkai Star Rail for an hour straight on maximum graphics settings). The cameras are very good, the photos are very detailed. And of course, the AI features are very cool, very useful in everyday life. The Privacy Display feature works very well, but I don't use it all the time and even when it's off, the viewing angles for other people are narrower. Another very important thing: the screen works perfectly in bright sunlight.

I’d been eyeing up ultras for a very long time. To be honest, this is my first Ultra; I’ve switched from the OnePlus models. So I can say that I’m very pleasantly surprised. The system’s optimisation is first-class; if you set it up properly the first time you start it up, you’ll have a very powerful and reliable phone in your hands. To be honest, I was a bit disappointed that the phone came out of the box without any screen protector or protective glass. It’s standard practice with Samsung, but even a basic screen protector would still be a nice surprise. Generally speaking, I can’t really criticise the phone; the drawbacks I’ve mentioned above are more or less common knowledge, and anyone considering buying this device will come across these points in reviews or discussions anyway. To sum up, the Samsung Galaxy S26 Ultra is a superb, high-performance device that certainly has all the hallmarks of the brand’s flagship model. If you’re thinking of buying one and have a practical use for such a device, you certainly won’t regret it.
High-end cameras
privacy display – despite its drawbacks, it’s a huge step forward and a brilliant feature
OneUI is very user-friendly
Even with a capacity of just 5,000 mAh, the battery life under normal use is almost two days (with a charging limit of 80%)
A stylus, which is very useful, for example, when editing photos
Speaker quality
Software support (7 years)
The latest Snapdragon
Storage speed
The privacy display reduces the overall brightness of the screen, but it can be easily integrated into ‘Modes’, so you can activate this feature, for example, only when using public transport
5,000 mAh battery; the capacity has remained unchanged for several years
Samsung’s pre-installed bloatware, which you can get rid of straight away and then you’re sorted

I haven’t had the phone for very long yet, so I can’t really judge it, but it’s a top-of-the-range model and the best phone this company has produced. I’ve had this Galaxy model several times in a row now and I’m absolutely delighted with it; I wouldn’t want to change it just yet.

This level of compatibility with wireless chargers will be hard to beat by the competition 🤡
The CPU has optimizations for running local LLMs with Q8 quantization.

The Samsung Galaxy S26 Ultra is a very decent phone. They are not just blank numbers on paper. The feeling in the hand is good, but it depends mainly on the appropriate packaging. The new One UI 8.5 system runs very smoothly and you don't have to wait for anything. When I compare it to the older S24 Ultra, the difference is noticeable. The S24 Ultra was a decent worker, but the current novelty is more fine-tuned, better photography is simply a class better, especially at night the resulting photo is noticeable thanks to the f/1.4 brightness. The 5000mA battery is decent, but could have been 6000-7000mA if it didn't significantly affect the dimensions. The display of the phone is also very good, but compared to the S24 ultra I could not tell the difference by eye.
Privacy Display
S Pen
Video stabilization
Fast 60W charging
Convex rear cameras (need a suitable case to keep the phone from wobbling)
Lack of English in AI functions (Call screening, translations, etc. )
