$799! Samsung Unveils Galaxy S25 Series: Slimmest Ever, AI Focus, and a Surprise!

A year ago, Samsung first ventured into AI smartphones with the Galaxy S24 series.

Features like circle search, real-time call translation, and generative photo editing compressed complex operations into simple buttons tucked into screen corners.

These features represented Samsung’s initial understanding of AI. After a year of refinement, Samsung has developed new insights into integrating AI with smartphones.

On Jan 23, Samsung officially launches the Galaxy S25 series, and there’s 「One More Thing」.

AI Evolution: Cross-Application and More Proactive

The Galaxy S25 series features a complete UI overhaul, upgrading One UI to the new 7.0 version.

The restructured One UI offers a more unified and aesthetically pleasing design, but more importantly, it represents a comprehensive evolution in human-computer interaction by deeply embedding AI into the system’s core.

This time their focus is on the multimodal perception capability achieved through the collaboration of Galaxy AI and Google Gemini. With this capability, the Samsung Galaxy S25 series’ ultra-human-like intelligent assistant can “see, hear, and understand” like a human, participating more proactively, intelligently, and accurately in daily tasks.

For instance, when you use the screenshot feature, a side panel will pop up.

In the panel, besides the usual edit or share buttons, there will be a feature called AI Select.

AI Select can anticipate your subsequent actions for the current screenshot and provide corresponding options, allowing you to complete follow-up actions with a single click, such as quickly generating a GIF.

This is a more proactive display of Galaxy AI, appearing wherever it can assist, providing “just-in-time” services at the right moment.

Today, recognizing text and images on the screen is considered a basic AI function, with major manufacturers performing excellently in this area.

However, the multimodal perception capability takes the Galaxy S24 series’ “circle and search” feature to the next level—it can not only see but also hear.

This doesn’t refer to natural language interaction but rather the AI’s ability to recognize sounds in videos currently playing on the phone. With this capability, you can precisely find that memorable segment in a large amount of data or identify the current video’s background music without opening other apps to listen and identify songs or laboriously searching through the gallery.

This intelligent experience adds a new dimension of “hearing” to search.

The intelligent upgrade brought by multimodal perception extends beyond video search to images as well—previously, finding photos in the gallery was always a challenge. With multimodal perception, users can simply describe in natural language, and Galaxy AI can conduct a comprehensive search of the gallery to accurately locate the desired photo.

For example, a simple command:

“Find the dog photo I took in the park last week with blue sky and white clouds in the background.”

Upon receiving the command, Galaxy AI can accurately find the target by combining time, location, subject, and image content. This “human-like” interaction eliminates the hassle of memorizing fixed commands, making technology truly invisible and more natural.

If the above capabilities represent a refined upgrade of single-point AI functions, then the platformization of AI brings a new capability that transcends application boundaries—the cross-application execution chain.

The limitation of traditional AI lies in the isolation of application permissions, restricting its functionality to a single application. The cross-application execution chain of the Galaxy S25, through system-level deep integration, successfully achieves global linkage, making task chaining smoother and seamless.

For example, if you want to book a Japanese dinner for tomorrow night and share the address in a WeChat group, you only need to voice this request to the phone. Galaxy AI will simultaneously call upon map, social, and calendar apps to automatically complete filtering, booking, sharing, and reminders.

In this process, two aspects are noteworthy:

  • No need to switch: All operations are seamlessly connected in the background, with results directly pushed to the notification bar.
  • Context understanding: AI can recommend dishes based on “dining preferences” in chat history and even suggest transportation plans based on group members’ locations.

Behind this series of performances is a more intelligent manifestation of Galaxy AI and system-level integration—opening AI capabilities to third-party applications to form a unified interaction protocol.

AI’s “proactive care” is more evident in the details.

Based on on-device learning capabilities, Galaxy AI can deeply understand users’ daily habits.

Through continuous learning of user behavior, AI will establish a personal knowledge graph. Based on the information provided by this graph, Galaxy AI can not only predict all-day needs but also provide messages, reminders, or suggestions at the right time, organizing them in one interface or intelligently filtering real-time information to present it directly on the lock screen, reducing the operational cost of obtaining information for users.

Don’t worry about this “proactive” AI disturbing you. Galaxy AI’s learning ability also plays a role in this aspect, continuously optimizing behavior patterns based on user feedback: if reminders are ignored multiple times, notification frequency will automatically decrease; if concise answers are preferred, lengthy explanations will be compressed.

This “adaptive learning” capability makes AI truly an extension of personalization.

However, as AI further enters the system level, gaining greater permissions and becoming highly personalized, privacy issues also need attention.

Samsung specifically states that all sensitive data (such as gallery content and schedule information) is processed on the device through a personal data engine, combined with post-quantum encryption algorithms and the Knox Vault security processor, ensuring “zero leakage” of user privacy.

Even the parsing of voice commands is prioritized through local NLP models, with end-to-end cloud collaboration only required in necessary scenarios.

Just like the Nexus phones in the Android era, Google is channeling its powerful AI paradigm into top-tier hardware.

After deep collaboration with Google Gemini, the Samsung Galaxy S25 is undoubtedly the AI phone better suited for most people.

This collaborative model might be replicated in more devices in the future, clearly giving Google a head start in the AI era.

Extreme performance often comes with increased heat, an unavoidable side effect in smartphone performance enhancement.

To efficiently harness performance in the compact Galaxy S25 body, Samsung customized the thermal interface material (TIM), increasing the heat spreader area by up to 40% to improve cooling efficiency.

Samsung Galaxy S25 camera features.

Performance boosts aren’t just for AI and gaming.

In the era of computational photography, taking photos is no longer just the CMOS’s job. Every image and pixel requires the phone’s chip to optimize imaging through algorithms.

Stronger chips naturally lead to stronger imaging hardware.

In the Samsung Galaxy S25 series’ flagship Ultra model, Samsung introduced a new ultra-wide-angle lens, upgrading from the S24 Ultra’s 12MP to 50MP, finally addressing the last shortcoming.

The ultra-wide lens might be the least used actively, but its passive activation frequency is quite high, mainly due to macro photography.

When the subject is too close to the lens, exceeding other lenses’ closest focusing distance, the phone automatically switches to the ultra-wide lens, utilizing its excellent close-focus ability for macro shots.

With a 50MP ultra-wide lens, the Samsung Galaxy S25 Ultra’s macro resolution reaches new heights.

With the existing 200MP wide-angle main camera, 10MP 3x telephoto, 50MP 5x telephoto, and 10x telephoto comparable to optical zoom, the Samsung Galaxy S25 Ultra achieves full focal length coverage from 0.6× to 100× with higher image quality.

Additionally, Samsung added a virtual aperture feature to the camera, using AI support and computation to express blur intensity through aperture parameters similar to professional cameras. However, this feature is still algorithm-based, and its performance in complex environments or with challenging edges like hair and sweaters needs real-world testing.

Notably, this feature can be used when shooting in Samsung’s Expert Raw professional photo format.

AI features also bring new possibilities to imaging.

The AI group photo feature, previously seen on the Google Pixel 9, is now available on the Samsung Galaxy S25 series.

This feature helps avoid awkward moments in group photos. AI selects the best expression for each person from multiple shots taken at the same location and seamlessly combines them into one photo, preventing closed eyes or inappropriate expressions at the shutter moment.

Compared to static image quality upgrades from hardware improvements, the real focus this time is more on video.

Due to body size limitations, phone CMOS sizes are physically constrained, directly affecting sensor sensitivity. Especially in low-light environments, smaller CMOS sizes can lead to image noise, affecting final image quality.

In static photography, phones can use night mode, employing multi-frame stacking to reduce noise and enhance image purity. However, this technique requires processing time, often taking several seconds to complete the entire shooting and compositing process.

Samsung Galaxy S25 low-light video capabilities.

Thus, in video recording, where real-time requirements are higher, this method isn’t applicable.

Here, powerful chips offer more possibilities. When traditional paths don’t work, performance and algorithms can “compute” better image quality.

Through real-time inter-frame analysis and pixel-level data processing, the Samsung Galaxy S25 series can perform dual analysis noise reduction during video shooting. With custom algorithms, it intelligently separates static and dynamic objects in the video, processing them separately, enhancing the Galaxy S25 series’ low-light video capabilities with less noise and more detail.

With these individual feature breakthroughs, Samsung has further enhanced the overall specifications of dynamic video.

In the Samsung Galaxy S25 series, Samsung has introduced 10-bit HDR specifications. The 10-bit capability offers over a billion colors, which is 60 times more than 8-bit, resulting in richer colors and smoother transitions.

The HDR format retains more details in both bright and dark areas compared to SDR, making the visuals closer to what the human eye perceives.

While these specifications might sound complex, the actual effect is straightforward—videos appear more realistic, vivid, and visually appealing.

However, the next feature is more specialized.

As video content becomes increasingly popular, Samsung has developed the professional Galaxy Log format. This format uses a special gamma curve to capture more details in highlights, shadows, and colors.

Correspondingly, Samsung has created LUTs for Galaxy Log to help professional users avoid “flat” footage and prevent exposure and white balance errors during recording.

It’s important to note that this format doesn’t significantly enhance image quality; it’s designed for post-production adjustments and is quite large in size. Non-professional users are not recommended to shoot videos in Log format.

Unified Design Language: Thinner and Lighter

In the Samsung Galaxy S25 series, one model has undergone a significant design change, which is quite interesting.

In a nutshell—on the Samsung Galaxy S25 Ultra, straight edges have become curved, and curved edges have become straight.

The straight edges refer to the four sharp right angles of the phone’s screen.

Traditionally, the Ultra models of the Samsung Galaxy S series, due to the presence of the S Pen and right-angled screen, were seen as the spiritual successors to the Note series.

However, on the Galaxy S25 Ultra, the design inherited from the Samsung Note series has come to an end—this generation features rounded screen edges across the board.

After discussing the design changes of the Ultra, let’s look at the overall changes in the entire series.

Samsung claims this generation is the thinnest S series ever, with all three phones becoming 0.4 mm thinner, and their weights have also been reduced compared to the previous models:

  • Galaxy S25 Ultra is 15 grams lighter, weighing 218 grams
  • Galaxy S25+ is 7 grams lighter, weighing 190 grams
  • Galaxy S25 is 6 grams lighter, weighing 162 grams

In addition to the thinner body and lighter weight, the front bezels have also become narrower. For example, the S25 Ultra’s bezels are 15% narrower than the S24 Ultra’s.

Samsung’s color game continues.

The entire Galaxy S25 series offers 14 color options, with the S25 standard and S25+ sharing the same color scheme, while the S25 Ultra has its own exclusive colors:

  • Samsung Galaxy S25 and Galaxy S25+: Ocean Blue, Cool River Blue, Frost Green, Twilight Silver, and online exclusives Midnight Black, Warm Coral Red, Soft Pink Gold
  • Samsung Galaxy S25 Ultra: Titanium Blue, Titanium Silver, Titanium Gray, Titanium Black, and online exclusives Titanium Soft Gold, Titanium Ink Black, Titanium Jade Green

At the event, we captured images of the Galaxy S25 Edge. Although we couldn’t experience it directly, we can see that the phone is extremely thin, with a high screen-to-body ratio and a punch-hole front camera.

Like the Galaxy S25 series, the Galaxy S25 Edge features a right-angled mid-frame, and rumors suggest the body thickness is around 6.5mm.

Notably, despite its thin body, the Galaxy S25 Edge still has a dual rear camera module, which is quite prominent.

Currently, no further official information about this ultra-thin phone has been disclosed, but rumors suggest it is positioned between the Galaxy S25+ and S25 Ultra, with a likely price of $999.

Finally, here are the prices of the three models released so far:

  • Galaxy S25 starts at $799
  • Galaxy S25+ starts at $999
  • Galaxy S25 Ultra is priced at $1299

Samsung’s Long-Term Strategy

Over the past year, the smartphone competition has resembled a fierce race: manufacturers flaunting specs, piling on features, and competing for various “first” titles.

Samsung was different—through its strong control over the entire supply chain, it integrates screens, chips, cameras, and other hardware into a precisely functioning “industrial artwork.” Based on this characteristic, Samsung’s approach can be described as steady and solid. However, in a market where hardware breakthroughs are slowing and competition is intensifying, the updates to the Galaxy S series may seem overly “conservative,” often involving mere fractions of a millimeter in thickness reduction or slight battery capacity increases.
