Samsung Galaxy S25 Ultra in hand: Transformed appearance, Human-like AI dominates the experience

While Samsung Galaxy S25 Ultra Still being launched at the event in the US, I had the opportunity to quickly experience this device in Vietnam and below are my initial comments about Samsung’s most advanced flagship model just released.

Design: A transformation in appearance

The first highlight and also the most notable change on the Galaxy S25 Ultra is the design. Samsung has made a spectacular “transformation”, bringing a completely new look, different from its predecessors. Instead of the sharp, square corners of the S24 Ultra, the S25 Ultra has softer, rounded corners, creating a modern and sophisticated feel. The frame is also completely flattened, replacing the previous curved design, keeping up with the design trend that is popular in the smartphone market today.

This change brings clear advantages in terms of grip experience. The rounded corners help the device hug your hand better, minimizing the feeling of tightness or hand pain when used for a long time, especially when holding the device horizontally to play games or watch movies. However, with a large screen size of 6.9 inches, plus flat edges, the S25 Ultra can still cause a slight feeling of discomfort, especially for users with small hands like me. This is unavoidable on large-screen smartphones, and users may need some time to get used to it.

According to information from Samsung, the S25 Ultra is also the thinnest Galaxy S ever, with a thickness reduced by 15% compared to the S24 Ultra. Unfortunately, at the event, I did not have an S24 Ultra available to directly compare the thinness between the two devices. Therefore, I will need to verify this information in the following detailed reviews. However, if this information is accurate, this will be a significant plus for the S25 Ultra, helping the device become more compact and elegant.

Regarding materials, Samsung continues to use a monolithic titanium frame for the S25 Ultra. Unlike some competitors who only cover the aluminum frame with titanium, the use of monolithic titanium brings more durability and sturdiness to the S25 Ultra. The device’s screen is also upgraded with the latest Corning Gorilla Armor 2 tempered glass, which Samsung claims is 29% more resistant to cracking compared to the S24 Ultra and reduces screen-related repairs by 60% compared to the previous generation. S24 Series and S23 Series. This is a valuable upgrade, helping users feel more secure during use.

Screen: Larger, sharp and smooth

The S25 Ultra’s screen has been increased in size to 6.9 inches, compared to 6.8 inches of the previous generation. The change, although small, brings the S25 Ultra on par with the screen size of the iPhone 16 Pro Max, making it one of the smartphone models with the largest screens on the market today. This will bring a more vivid and eye-catching entertainment experience, watching movies and playing games.

Other parameters of the screen remain the same as on the S24 Ultra, including QHD + resolution, adaptive scanning frequency from 1 to 120Hz and Samsung’s famous Dynamic AMOLED 2X panel. Thanks to that, the S25 Ultra continues to deliver excellent display quality with vibrant colors, high contrast, impressive brightness and wide viewing angles. The 120Hz scanning frequency ensures that all swipes, touches, and page scrolling are smooth and seamless.

AI artificial intelligence: Core highlights, enhancing the experience

One UI 7, pre-installed on the S25 Ultra, brings a series of groundbreaking AI features, which Samsung calls “Human-like AI Agent” – Almost human-like AI assistant. AI on S25 Ultra is deeply personalized, aiming to minimize hand operations and enhance voice interaction, providing a smarter and more convenient usage experience than ever.

AI Select: This feature automatically recognizes content displayed on the screen. For example, when watching a video, AI Select can create a GIF from it; When you circle an object, this feature provides detailed information about that object, including related images, videos, audio, and text.
Smart voice search: Voice search capabilities are widely applied in many applications, especially in photo managers. Users can use voice commands to search for photos based on objects, animals, subjects, locations, and AI will automatically analyze and provide accurate results, completely eliminating the need to search. Time-consuming manual work. This feature also applies to search in settings, allowing users to give natural voice commands like “make display text larger” to adjust display settings.
Cross Action – Cross-app action: This is an extremely useful AI feature that simplifies complex tasks with just a single operation. By holding down the power button, users can command the AI assistant to perform cross-app tasks. For example, you can say “Send me the Arsenal football team’s match schedule and add it to my calendar”, and the AI will automatically search for the information, then automatically add the match schedule to your personal calendar app. .

Cross Action can also be applied to many other situations such as searching for information and sending messages, searching for information and scheduling, summarizing YouTube videos and saving to notes app, searching for restaurants and saving to notes I often send the restaurant address in the message. AI even allows scanning ingredients in the refrigerator and suggesting suitable recipes. This feature supports both native Samsung apps and third-party apps, opening up countless possibilities for convenient usage.

Now Brief: This feature provides contextual, time-based personalized information. For example, in the morning, Now Brief will display the weather forecast, health information from the Samsung smartwatch, and the day’s schedule. Now Brief can also summarize events, snapshots, reminders about expiring coupons or travel tickets.

Smart lock screen with Now Bar: The lock screen on the S25 Ultra has been redesigned with the smart Now Bar taskbar, quickly displaying useful information in real time such as match results, map navigation, and notification updates from the application. Call a car, order food.

Security “to the teeth”

With a series of personalized AI features, user data security becomes even more important. Samsung is committed to protecting personal information by encrypting and protecting it through Samsung Knox Vault – an in-depth security platform that combines specialized hardware and integrated software. Samsung also equips advanced post-quantum data security capabilities, ensuring absolute privacy for users.

Performance rests on the shoulders of Snapdragon 8 Elite For Galaxy

The entire S25 Series, including S25, S25+ and S25 Ultra, are equipped with the Qualcomm Snapdragon 8 Elite For Galaxy processor, specially optimized for Galaxy devices. According to Samsung, this processor helps handle AI tasks quickly and accurately thanks to a 40% more powerful NPU, 37% more powerful CPU and 30% more powerful GPU than the previous generation. Ray Tracing processing ability has also been upgraded by more than 40%, promising to bring the ultimate gaming experience.

The cooling system has also been significantly upgraded, with the vapor chamber on the S25 Ultra being 40% larger than the S24 Ultra, and on the S25/S25+ 15% larger than the S24/S24+. This helps ensure stable performance, even when performing heavy tasks for long periods of time.

Another notable upgrade is the amount of RAM. The entire S25 line has been upgraded to 12GB of RAM, instead of 8GB like on the S24. Larger RAM capacity makes multitasking smoother, especially when using AI features. Internal memory options remain the same as 256GB, 512GB and 1TB.

However, the battery capacity of the S25 Ultra remains the same at 5,000mAh, equivalent to previous generations. This is the point that makes me feel a bit disappointed, because competitors are constantly upgrading the battery capacity on their flagships, even up to 5400 – 5600mAh for devices with screens smaller than the S25 Ultra. With a large 6.9 inch screen and many AI features, keeping the battery capacity at 5000mAh may affect the device’s battery life.

Camera: Upgraded super wide-angle sensor, optimized by AI

The S25 Ultra’s rear camera system still includes 4 cameras, with a 200MP F1.7 main camera. The most notable upgrade is the super wide-angle camera, increased resolution to 50MP, F1.9 aperture, supports autofocus and macro photography. According to Samsung, this upgrade increases resolution and detail by 4 times compared to the 12MP ultra-wide camera on the S24 Ultra. The two telephoto cameras retain the same parameters, including 3X 10MP F3.4 telephoto camera and 5X 50MP F2.4 telephoto camera. The front camera is still 12MP F2.2.

Samsung also equipped new AI algorithms to help reduce noise, increase detail when shooting in low light, and the Best Face feature makes editing portrait photos easier. Another interesting AI feature is Audio Eraserallows removing unwanted noise when recording videos, with the ability to classify noise details into categories such as voice, crowd, wind, music, nature, noise, and allows users to customize edit idea.

Selling price and release date

Some major mobile phone retail systems in Vietnam have allowed pre-ordering of the S25 series, with an expected starting price of 24 million VND for the S25, 28 million VND for the S25+ and 35 million VND for the S25 Ultra.

Initial conclusion

It can be seen that Samsung Galaxy S25 Ultra is a valuable upgrade with a transformed design, larger screen, powerful performance and especially extensive integration of artificial intelligence. New, smart and convenient AI features truly elevate the user experience, turning S25 Ultra into a powerful personal assistant.

However, keeping the 5000mAh battery capacity is a minus point, and needs to be further verified for actual usage time. Overall, the S25 Ultra is a very desirable flagship, promising to shake up the smartphone market in the near future.

Above are my quick reviews of the Samsung Galaxy S25 Ultra based on the information provided and actual experience. I will continue to update more detailed information in in-depth reviews when I have the opportunity to use the device for a longer period of time. Please pay attention and watch on GameHov!
