By far the greatest phone ever
on December 5, 2025
Posted by: Slothman
[This review was collected as part of a promotion.] The Galaxy S25 Ultra is hands down the best phone I’ve ever owned. The camera quality is insane—photos come out crisp with amazing detail, even in low light. The performance is lightning fast, no lag at all, and the battery lasts all day without even trying. The screen is super bright and smooth, and the build quality feels premium. Samsung really outdid themselves with this one. If you’re thinking about upgrading, this is absolutely worth it

Phone Works Great
on December 5, 2025
Posted by: NoOnEMaJoR
[This review was collected as part of a promotion.] Man, I use my Galaxy Ultra 25 for everything: gaming, surfing, paying you name it, I do it on my phone. I even use the Galaxy AI to help me shop, figure stuff out, or just ask it about something that's been bugging me. It handles everything perfectly. The only thing is, the battery drains pretty fast when I'm streaming, gaming, or whatever! Other than that, I love this thing, no complaints. Oh, and I can't forget the memory. I've got the 256 GB model, so I can load up on apps, and they all run super smooth, no lag or buffering whatsoever!

I loved the s10 plus and its features.
on December 5, 2025
Posted by: MissMyS10Plus
[This review was collected as part of a promotion.] S25 ultra feels boxy and feels and looks like a step backwards. The text messages can no longer be customized. It is a bit awkward when trying to hold in one hand. I drop it frequently. I really enjoyed the look of the beveled edges on the s10 plus it made the cases thinner and easier to hold. It is fast and responsive. Battery never last an entire day without charging.

Best phone I've ever had since the S1
on December 5, 2025
Posted by: Metaltekhead
[This review was collected as part of a promotion.] If you’re looking for a phone that can truly do everything and then some, the Samsung Galaxy S25 Ultra is on another level. I’ve owned a ton of smartphones over the years, and nothing even comes close to what this thing delivers.
The camera alone is insane. The clarity, the dynamic range, the detail… it’s like carrying a professional setup in your pocket. Expert RAW makes every shot feel cinematic, and low-light photos look like they were taken with a full-size camera. Winter shots, night shots, fast motion — it handles it all without breaking a sweat.
Performance is flawless. This thing is lightning fast. Apps open instantly, multitasking is smooth, and even heavy usage—navigation, deliveries, scanning, video, and music—all at once doesn’t slow it down. The battery life is wild too; it easily gets me through a full day of real-world use.
The screen? Absolutely gorgeous. Bright, crisp, colorful — you can see everything perfectly even in direct sunlight. Watching videos, editing photos, gaming, scrolling… it all looks next-level on this display.
What I love most is that the S25 Ultra just feels reliable. No lag, no hiccups, no fuss. It’s the kind of phone that makes everyday stuff easier and the fun stuff way better. For anyone who wants the best camera, the best performance, and the best overall experience — this is the phone to get.
Hands down the best device I’ve ever owned.

Galaxy S25 Ultra: Power, Camera, and Speed
on December 5, 2025
Posted by: JlovesSamsung
[This review was collected as part of a promotion.] I’ve been using the Samsung Galaxy S25 Ultra for a while now, and it has quickly become the most capable phone I’ve ever owned. The overall performance is incredibly fast and smooth—apps open instantly, multitasking is effortless, and the new chipset makes everything feel more responsive than previous models.
The display is one of my favorite features. It’s bright, sharp, and vibrant, making videos, photos, and even simple browsing feel immersive. Outdoors, the visibility is excellent, and the adaptive refresh rate keeps everything fluid without draining the battery too quickly.
The camera system is where the S25 Ultra truly shines. Photos come out crisp with impressive detail, even in low light. The zoom performance is cleaner and more stable than before, and the AI enhancements noticeably improve clarity without making images look artificial. Video recording is equally strong, delivering smooth footage with great stabilization.
Battery life has been reliable. It easily lasts a full day with mixed use, and charging is faster than I expected. The build quality feels premium, and despite its size, the phone is well-balanced and comfortable to hold.
Overall, the Galaxy S25 Ultra is powerful, polished, and packed with features that actually make a difference in daily use. It’s a device I enjoy using every day, and I feel confident recommending it to anyone wanting a top-tier smartphone experience.
