Best Phone Ever
on October 8, 2026
Posted by: Coxs06
[This review was collected as part of a promotion.] Camera quality is superb especially when used at nights as the night detection option gives that quality light addition effect. Audio is amazing. RAM runs excellent. Phone runs smoothly and quickly. The 512gig model gives all the storage you need and more for both applications, videos and pictures.

Not good
on October 8, 2026
Posted by: Libi
I purchased the Samsung Galaxy S25 Ultra expecting a top-tier flagship experience, but the reality has been deeply disappointing. Since July of this year, the device's performance has dropped drastically, suffering from constant lag, excessive overheating, and rapid battery drain.
I have been extremely careful with this phone from day one: I never leave it charging overnight, I don't keep unnecessary apps installed, and I use it under completely normal conditions. I have meticulously followed every single optimization tip provided by customer support to improve battery life, but nothing has worked.
It is unacceptable for a phone in this price range to experience this level of battery degradation after just one year of use. Unfortunately, this is not my first bad experience with the brand; I had the exact same issue with a Samsung smartwatch whose battery became useless after a year. Given this recurring pattern of product durability issues, I have completely lost faith in the brand and have decided to switch to other manufacturers for the rest of my family's devices. I do not recommend this phone.

Loving my Phone!
on October 8, 2026
Posted by: BlueTaz
[This review was collected as part of a promotion.] I have been wanting a Samsung for a LONG time lol and i finally got one! ☺️ I really love my Samsung S25 Ultra! I chose the S25 Ultra version off of the phone my sister has, which I thinking an S23. I absolutely LOVE the fact that I can zoom into the moon 🌑 and get AMAZING photos! You can see all the craters! I was issuing my phone for all kinds of stuff but mainly photos and schooling. Only thing that i wish is if it had more storage for photos 😅 I love taking pictures what can I say lol!

Excellent phone
on October 8, 2026
Posted by: Gigi18s
[This review was collected as part of a promotion.] The phone's camera is excellent; I've taken photos of the moon and they turn out beautiful—the best camera and the best phone. Movie resolution is excellent; Samsung is always the best—I wouldn't trade it for anything. I like the software; it's easy to use

[This review was collected as part of a promotion.] I chose the the Galaxy S25 Ultra. This phone is great. The battery life is better than any of my past phones. And the processor is super fast, which helps me in my daily work activities. The cameras are amazing, I have to take a lot of pictures in my job. And the detail and quality of the pics is the best I've seen. Overall, I'm extremely happy with this phone. I've had it a little over a year and it has and still exceeds all of my expectations.
