Access to DeepSeek, double the AI experience?

The weather in Guangzhou is really a bit bizarre.

It has just passed the long "winter" for the old Cantonese, and just welcomed the familiar thirty-plus degrees, and then the cold air comes down from the south bringing strong convection. As a result, amidst a series of deafening thunder, the wet plum rain weather began.

In my opinion, March is not a lively month. When the sky is overcast and seems to be pressing down on your face, the incandescent lamps in the office building become the rare lighting in this haze. It seems that no one can muster the energy to do anything, and even the earth appears exhausted.

But Samsung is not like this. Samsung is still very energetic.

Therefore, on March 4th, in the wet air of Guangzhou, Samsung specially held a new product tasting event. The protagonist was a series of new products including the Samsung Galaxy S25 series. Lei Technology was invited to attend the tasting and communicate with Samsung staff to gain a deeper understanding of their ideas about AI mobile phones.

At this event, Samsung focused on introducing some selling points of the S25 series mobile phones that were not previously emphasized, allowing me to gain a deeper understanding of the usage and characteristics of the new generation of Samsung flagship products, especially the updated "Galaxy AI" and the new Bixby, which are even interesting enough to make me cheer up and introduce them to you properly.

Simple and tough, low-key and elegant

But as usual, let's start with the product.

After all, you can't touch such a complete set of Samsung flagships everywhere. Lei has previously only reviewed an ultra-large cup model, and it is rare to have the opportunity to actually use it, so it is definitely necessary to touch it first.

In terms of appearance, the Samsung Galaxy S25 series continues the design style of previous generations, with a relatively simple overall shape.

The fronts of the S25 and S25+ are familiar equilateral straight screens, with basically no major changes in parameters and shape, while the borders of the S25 Ultra have been significantly narrowed, even appearing more extreme than the smaller-screened S25, which can really be described as "all screen on the front".

On the back of the phone body, you can see several iconic vertically arranged cameras. This time, a record-style decorative ring has been specially added to increase recognition. The connection between the phone cover and the metal middle frame is quite solid, which is a sense of delicacy brought about by strict quality control.

However, as Samsung said, the S25 series is the thinnest S series ever made by Samsung. All three phones have become 0.4 millimeters thinner, and at the same time, compared with the same model of the previous generation, the weight has also decreased, with the S25 directly reaching the level of 162g.

For comparison, my main small-screen phone last year, the Xiaomi 14, has a total weight of 193g.

In actual use, the Galaxy S25 with a 6.2-inch small screen is indeed the most amazing. The feel of the aluminum alloy middle frame is excellent. With a width of nearly 70mm and a weight of 162g, it gives a false impression of insubstantiality. Coupled with the streamlined integrated design, one-handed operation is completely stress-free. It may be the most exquisite Android small-screen flagship currently on the market.

In terms of color, my personal favorite is Warm Coral Red. It is more like a deep pink when seen with the naked eye, but it does not have the orange-yellow tone of the previous Pixel series coral color. In short, it is a vibrant color scheme.

Of course, the Far Sea Blue I got on site is also good.

As for the configuration, with the support of the new Snapdragon 8 Ultimate Edition (for Galaxy), the Samsung Galaxy S25 series can easily score high points in the on-site environment. At the same time, benefiting from the larger area of the VC vapor chamber, heat dissipation performance and stability have also been further enhanced.

If you are interested in the Samsung Galaxy S25 series products, you can check out Lei's in-depth review written before. Here, I will not go into details.

Unlocking a new experience of mobile phone AI

This time, Lei went to the scene not only to actually use the full set of Samsung Galaxy S25 series, but also to see how Samsung would use AI technology to enhance the user experience and productivity of flagship models.

According to the official introduction, the renewed Galaxy AI, through powerful AI computing power, innovative AI applications, and the new Samsung One UI 7, can more accurately understand user needs and provide efficient and personalized services with multimodal perception and cross-application execution capabilities, turning the phone into a user's AI partner.

And the first keyword here is "multimodal".

What is multimodal?

The previous Galaxy AI could only accept text/voice input and provide processing feedback, like a robot living in a dark room communicating with you through letters, unable to speak, move, or see. This is the so-called single modality.

Multimodality refers to a system or technology that can simultaneously process multiple types of information, such as text, images, sounds, etc., just like humans understand the world through multiple ways such as seeing with eyes, hearing with ears, and speaking with mouths, synthesizing this information to complete more complex tasks.

For example, I randomly opened Bixby at the tasting event and asked it to recognize what I was drinking.

It smoothly recognized that it was a glass of milk and provided three directions that I might be interested in for expansion.

Next, let it take a look at this mineral water distributed on site.

The new generation of Bixby indicated that it was a bottle of Dasani brand mineral water. Dasani is a bottled water brand launched by Danone, and it is not the same product as the Pepsi Pure Water distributed on site.

Then I searched for the packaging of Dasani...

The similarity is such that mistaking it is understandable.

In addition to the new generation of Bixby, the Samsung S25 series has adopted multimodal capabilities on a large scale. For example, a bottom pop-up window will now appear when taking a screenshot.

Inside the pop-up window, in addition to the common edit or share buttons, there will also be a function called "AI Multi-Screenshot". This function can predict your subsequent operation needs for the current screenshot and provide corresponding function options.

When the user selects a note containing time and address information, the AI can quickly and accurately recognize it and automatically pop up options such as "Save to Calendar".

This is also the best embodiment of the second keyword, "cross-application execution".

In addition to being able to use the new generation of Bixby to mobilize multiple applications, now our familiar instant search function allows you to use your finger to circle the content you want to search for on any interface, and then AI will present high-quality search results. At the same time, it will further analyze and predict intentions, saving us the next steps of operation.

Even the background music in the video can be accurately recognized through "Instant Search", and it can even automatically capture the video content to create a GIF animation for sharing.

DeepSeek, which everyone is very concerned about, has also been officially installed on the Samsung S25 series.

After actual testing, you can either pin the DeepSeek plugin to your negative one screen through the "Smart Agent" application, or ask the new generation of Bixby to think deeply after inquiring, so as to realize the invocation of DeepSeek-R1.

I asked it if it knew "Lei Technology", and the final answer was pretty good.

As for One UI 7 itself, in addition to the rounder icon design, the greatly revamped control center has also become much rounder. This year, Samsung has added the Now Bar "real-time window" to the system, which can display notifications, music, countdowns, recordings, and other information on the lock screen.

It's like this, multiple real-time windows can be stacked together, and they will continue to enlarge after being clicked, making it convenient to obtain more information and perform operations.

Summary: AI is imperceptible, but it is an AI mobile phone that is everywhere

If we say that the previous domestic launch event held by Samsung was mainly to introduce the new selling points of the Galaxy S25 series.

Then the media tasting event held today is to allow us media editors to personally experience the charm of the S25 series, especially the unique concept of the renewed Galaxy AI and what useful functions have been added compared to previous years.

From the hands-on experience, the Galaxy S25 series is still a highly completed flagship mobile phone series, with comprehensive consideration for both design and interaction, and is very competitive. This also makes people look forward to the landing of the ultra-thin product S25 edge.

On the functional experience side, the S25 series has also rarely infiltrated AI into every corner of mobile phone use, turning AI from a "new function" into a "part" of the mobile phone.

It does not provide a fixed dialog box-style AI entry like domestic mobile phones, but distributes AI functions to more usage scenarios. There is humanized interaction led by the new generation of Bixby, AI multi-screenshot that actively recognizes user needs, and seemingly good cross-application global linkage. Even DeepSeek has been added recently.

The best technology is to make people not feel the existence of technology.

The Samsung Galaxy S25 series is indeed striving in this direction.
