Everything I Could Imagine
on June 19, 2026
Posted by: Gingerwithsoul
[This review was collected as part of a promotion.] The Galaxy S25 Ultra's plethora of features span beyond those I could imagine having. Galaxy AI is an understated plus as it only adds more options and enhancements to help my daily tasks flow more efficiently. I spend over half the day working from my phone, so whether the task involves photography, photo and video editing, streaming movies, performing geological research, or just simply scrolling through social media, I know I can accomplish everything I need to with this stellar device! I am looking so forward to the day I can upgrade to the newest Galaxy device.

[This review was collected as part of a promotion.] I play several games, stream and do my banking. The phone has become an attachment for my hand. Use it all the time. The camera does great and very easy to edit the photos.

Galaxies AI
on June 18, 2026
Posted by: Bkmau29
[This review was collected as part of a promotion.] Samsung Galaxy AI fundamentally redefines the modern smartphone experience by turning complex artificial intelligence into highly practical, everyday tools. Rather than relying on tech gimmicks, Samsung has successfully integrated intelligence directly into core user habits, making daily workflows significantly faster and smoother.

Wonderful features but useless with dead battery
on June 18, 2026
Posted by: bklabel
[This review was collected as part of a promotion.] Galaxy AI is an intelligent device. I use it as my GPS and to talk with Chatgpt and Google a lot. Great cameras. But it is use less to me if after 7 hours the measly 5000 maH battery is empty. Make the phone 30% .thicker and double the battery size. Your competition's solid state batteries are much better.

I liked the Note 20 Ultra better. No AI.
on June 18, 2026
Posted by: KeepItSimple
[This review was collected as part of a promotion.] I loved the Note 4. I liked the Note 20 Ultra, but the S25 Ultra is too big and I don't like the AI trying to do everything. I spend too much time correcting the AI.

Samsung Galaxy S25 Ultra love
on June 18, 2026
Posted by: OMEN1nONLYSamsung
[This review was collected as part of a promotion.] I absolutely love my Galaxy S25 Ultra. In fact I like it so much I'm going to hold off on the upgrade until they make a significant improvement over this model. My Ultra paired with Galaxy AI and my Watch 8 Classic, can't be beat in my opinion. This phone is lightning fast. Has storage for days. I am a loyal to a fault Samsung user. I love all of their products but this phone is my favorite so far. THANKS SAMSUNG!
