[This review was collected as part of a promotion.] The Samsung Galaxy S25 Ultra is an amazing phone. It's fast, has an incredible camera, and the battery easily lasts all day. The display is beautiful, and the S Pen is a great bonus. Definitely one of the best phones I've owned! The Galaxy AI is out of this world!!!

Best so far!

[This review was collected as part of a promotion.] I've owned smartphones from several brands over the years, but my Samsung Galaxy S25 Ultra has been the best experience I've ever had. What really sets Samsung apart isn't just the phone—it's the entire ecosystem. My phone works seamlessly with our Samsung TVs, smart home appliances, Galaxy watches, and tablets through SmartThings, creating one connected experience that's incredibly convenient.
The AI features have genuinely impressed me. From productivity tools and photo editing to real-time assistance and everyday tasks, Galaxy AI has become something I use daily. Everything feels intuitive, fast, and designed to make life easier instead of more complicated.
SmartThings has also given me real peace of mind. Whether I'm checking on devices while I'm away, controlling appliances remotely, or receiving notifications, I always feel connected to my home. The integration is smooth, reliable, and works exactly the way you'd hope it would.
Samsung has created an ecosystem where every device complements the others, and once you experience that level of connectivity, it's hard to imagine going back. The build quality, performance, innovation, and AI capabilities make the Galaxy S25 Ultra an outstanding flagship device. If you're already invested in Samsung products—or you're thinking about it—I highly recommend it. It has completely changed the way I interact with my technology every day.

Premium flagship experience at its best
on July 26, 2026
Posted by: Jackal
[This review was collected as part of a promotion.] I can't say enough good things about this phone. It was my first android phone in many years. My last android before this was the Galaxy S3. Definitely sticking with Samsung after this experience. From the external aesthetics of the phone to One UI it's a great package. The camera is unbeatable in my opinion.
Everything is as buttery smooth and fast as when I first purchased it. (Have had it about a year and a half now) Came from the fruit phone and after about a year and a half it was noticably slower and battery degradation was becoming an issue. Not an issue with this phone.
I work in construction and I don't baby the phone but I've never had any issues with it's durability. Does literally everything I need it too. I have received quite a few updates since I've gotten it that have only made the experience better.
The Galaxy AI features combined with the baked in Google AI features are actually really impressive. Never cared for the phone assistants of old but this is a whole different experience.
Specifically, I've had some photos completely saved from using the AI to tweak the photo. I've got two kids and getting them both to sit right and smile for a photo is almost impossible. Using some of the AI photos editing, I'm able to always get at least one good shot of the family.
Even in 2026, this is still a very impressive phone. I'd recommend it to anyone looking for a premium flagship experience or if you just want a really good camera.

The ultimate phone
on July 25, 2026
Posted by: Ilikecatz
[This review was collected as part of a promotion.] This is the most powerful phone I have ever had. It can run any app or game I throw at it. Along with that, the screen is huge, allowing me to relax and watch videos on it. But the best part is, with GALAXY AI, I can check the grammar and spelling and not have to worry whenever I need to send texts or emails.

The Best Phone I've Ever Owned
on July 24, 2026
Posted by: Goldie
[This review was collected as part of a promotion.] I absolutely love my Galaxy S25 Ultra. I've been a huge fan of the Galaxy Ultra series ever since the S21, and each new generation just keeps getting better. Samsung has never disappointed me.
The camera is outstanding. In fact, it's usually better than many of my friends' phones, and they often ask to borrow mine whenever we want to take pictures because the photos turn out so much better.
The battery life is excellent and easily lasts all day, even with heavy use. The performance is incredibly fast, and searches load almost instantly. On the rare occasions when I've forgotten my phone and had to use someone else's, it felt like it took forever for search results to appear. It really made me appreciate just how fast and responsive my Galaxy S25 Ultra is.
I've also been really impressed with Galaxy AI. I use it all the time to help me search for information, improve my writing, and make everyday tasks quicker and easier. It's one of those features you don't realize you'll use so often until you have it.
Another feature I absolutely love is the S Pen. I use it constantly, especially when editing photos. It gives me much more precision than using my finger, whether I'm making detailed edits, selecting objects, or adding quick notes. Once you get used to having it, it's hard to imagine owning a phone without it.
If you're looking for a smartphone with an incredible camera, long battery life, lightning-fast performance, useful AI features, and the versatility of the S Pen, I
