Galaxy S25 Ultra: A history of Samsung Ultra flagship smartphones

Samsung is all set to unveil the Galaxy S25 Ultra as its next major flagship smartphone, it will pack high-end specifications, which have a history of development to reflect this device.
Samsung’s way to Android dominance goes through its S-series but its legacy is cemented by the Note-series, a formidable flagship lineup that has made a separate consumer base, especially for large screens.
Over the past decade, smartphones become taller and slimmer, including the screen size. These two lineups slowly caught up with each other. Eventually, Samsung bid farewell to the Note series.
Before ending the Note, the phone maker introduced an Ultra model in both lineups. And then, Note’s features were inherited into one and only Ultra phone.
That’s it for a briefing, let’s a look at Samsung Galaxy S25 Ultra predecessors’ history and how it changed through the past years.
Galaxy S20 Ultra
Released in February 2020, the first Ultra smartphone was accompanied by the S20 and S20+. It was released with extra specifications that don’t count as normal.
S21 Ultra sports a 6.9-inch Quad HD+ Dynamic AMOLED 2X screen with a hole-punch design, bringing a new look to the phone alongside 120Hz refresh rate support. It is equipped with Qualcomm 865 5G and Exynos 990 chipset, 12GB/16GB RAM, and up to 512GB storage, which can be expanded to 1TB with a microSD card.
The rear side has a big camera bump with four openings for a 108-megapixel main camera, a 12MP ultra-wide angle, and a 48MP telephoto camera along with a DepthVision sensor.
This was the first phone with a 108MP wide-cam, providing ultra-clear images and videos. It’s also the first to utilize a periscope zoom camera module, calling it space zoom at 100X digital. Meanwhile, the front has been upgraded 40MP selfie camera.
This phone had a 5,000mAh capacity, it’s the largest battery used in any previous S-series phone. However, these specs later surfaced in the Note 20 Ultra.

Galaxy S21 Ultra
Samsung started polishing the Ultra model with this release, slightly reducing the screen size to 6.8-inch with adaptive 10-120Hz refresh rate and HDR10+ content support.
The S21 Ultra also reduced the display curves, which were subtle but enhanced the overall outlook. From here, the company started turning pages in this particular segment with future releases.
The performance was improved with Qualcomm Snapdragon 888 5G processed with 5-nanometer technology. The camera design was more versatile and appeared integrated into the top left side of the frame. As an upgrade, the S21 Ultra brought dual telephoto cameras.
Importantly, Samsung didn’t release a new Note device and officially confirmed the Note 20 as the last device in the lineup.

Galaxy S22 Ultra
Released in February 2022, Samsung blended the characteristics and features of the Note 20 Ultra and integrated the latest technologies to launch the S22 Ultra. That’s where the S-Pen first made its debut in the S-series inside the device and not as an additional accessory.
Remarkably, the phone became boxy with sharp corners while using the curved edge screen. The camera setup continues from the predecessor and the device was packed with Snapdragon 8 Gen 1 chipset. Furthermore, the memory option is limited to 12GB and the storage is increased up to 1TB.
Meanwhile, support for a 45W super fast charger, which restores up to 65% power in 30 minutes.
What’s more is that Samsung upgraded its software update promise and started offering four years of OS upgrades and five years of security updates with the S22 series, which also expanded to its predecessor.

Galaxy S23 Ultra
Released in February 2023, the S23 Ultra comes with a major 200-megapixel main camera sensor. This sensor provides super high resolution and enhanced night photos and videography.
Furthermore, it the powered by a Snapdragon 8 Gen 2 chipset for enhanced performance. The design had no major changes except for some optimizations and new colors. Still, this was a substantial upgrade for users who wanted to go over to a new flagship.

Galalxy S24 Ultra
Released in January 2024, the Galaxy S24 comes as the most refined Ultra model and the closest hint to S25 Ultra.
The phone adopted a flat display, removing its marquee curved screen that Samsung carried for nearly a decade.
It has coated an anti-reflective layer that holds the light reflection and helps you to see the on-screen content with increased brightness even in broad outdoor conditions.
The sides are flatter than ever thanks to the flat screen panel. Moreover, the company adapted titanium material for the first time ever, improving its strength and looks.
On the camera side, the phone doesn’t hold back either, its nightography has improved over S23 Ultra. It has added a 50-megapixel periscope zoom camera with 5X optical zoom, which was at 10MP in the S23U.
Starting S24U, Samsung also eliminated the 8GB RAM option and users can only choose storage with 12GB RAM.

A new benchmark
In the same year, the South Korean tech giant launched 7 years of OS upgrades and security updates for the S24 and S23 series. Improving the 4-year OS upgrade cycle to this new milestone. These updates improve the user experience and expand the smartphone’s lifespan.
One UI
One UI has come so far alongside the Ultra lineup and it has introduced many new features that simplify the user interface. Not only that, the latest One UI 7 is the best version with many new graphical upgrades that will unpack with this smartphone.
Galaxy S25 Ultra
Samsung will unveil the Galaxy S25 Ultra on January 22 at an Unpacked event. The ultra will shift the paradigm and bring a completely reinvented itself for consumers.
A major implication of this new change will be visible on the design side. This article is a spoiler free and we don’t want to take the hype away for newcomers. So you can wait and tune in for the launch event tomorrow live online or check our S25 Ultra section for all of the things that we caught in the past.

Will you get the Samsung One UI 7 update in February 2025? [Updated]

Where is the One UI 7 update for my Samsung Galaxy device? YES, this is the most trending question among Galaxy users all around the world.
You see it everywhere – on tech forums, X threads, and YouTube comment sections. People are desperate for the new features, better security, and fresh look of One UI 7. This update is not just about making things run smoother, it is about new AI stuff that could change how we use our phones.
But since Samsung rolls out One UI updates at different times for different phones and countries, everyone’s wondering: when will I get it?
The stable version of One UI 7 was released at the same time as the new Samsung phones, the Galaxy S25 series. These phones were unveiled on January 22, 2025, and come with One UI 7 pre-installed. However, for those not upgrading to the S25, if you’re holding onto your Galaxy S24 or earlier models, the stable update is now in sight.
The stable update for existing devices, including the S24 series, which has been in beta testing and has received multiple beta builds, is expected to start rolling out in late February 2025. There’s also talk about the 4th beta build for the Galaxy S24 series before the stable rollout. However, we still do not have confirmation on when there will be a stable or beta rollout for the Galaxy S24 series or other older Galaxy devices.
I have also confirmed with Samsung Support in the US, that they have no idea about the One UI 7 release date. You can read the statement below.

Keep an eye out in February if you’re on the Galaxy S24 series or other eligible devices, as that’s when Samsung is expected to start expanding the stable update’s availability.

Samsung Galaxy S25 Ultra vs S24 Ultra: Side by Side Comparison – Looks and Dimensions

Samsung Galaxy S25 Ultra has some new design upgrades and we’ve put this phone side by side with S24 Ultra and stacked over each other to show you the closest comparison.
S25 Ultra vs S24 Ultra – Top and Bottom
S24 Ultra’s top and bottom view shows a flat surface with arcs on both ends, creating angular corners. The new device also has a flat top and bottom but with curved corners and a lower width. On paper, the S25 Ultra is 77.6mm and the S24 Ultra is 79mm wide.
The top contains a secondary microphone and an air vent hole with reduced space in the new phone. The GPS antenna is slightly moved to the left.

The bottom has two main antennas, offset from the previous position. The SIM card tray hole is now on the opposite side of the S24 Ultra, followed by the microphone. The USB Type C (charging/headphone) port remains the same.
Samsung has increased the speaker width, which may improve the sound. Another thing to notice is S-Pen’s head is thinner in the new flagship.
S25 Ultra vs S24 Ultra – Left and Right
The S25 Ultra has flattened the curved frame and it contributes to a slim form factor at 8.2mm. These two changes bring the new device to 218 grams in comparison to Galaxy S24 Ultra with 233 grams weight.
The right side has volume and power buttons and more antennas. The left side has no physical keys.

S25 Ultra vs S24 Ultra – Front
With those round corners and a flat frame, the S25 Ultra offers a more visually appealing front. This decluttering of extra width has created room for a 6.9-inch AMOLED display within an identical height (162.8mm) as the S24 Ultra (162.3mm) with a 6.8-inch screen.
Unfortunately, both phones have the same panel and there are no significant changes to find in terms of quality or brightness.
The new device uses Corning Gorilla Armor 2 + anti-reflective glass ceramic for better protection. To be mentioned, the anti-reflective protection was introduced with S24U.

S25 Ultra vs S24 Ultra – Back
S25 Ultra and its old version have the same rear frosted glass finish. The cameras are organized on the top left including an ultra-wide angle, a main camera, and two telephoto cameras. The setup also consists of a laser autofocus sensor and an LED flash.
These lenses have bigger crows glued on top. In my opinion, the S24 Ultra’s rear camera crowns look way better than these dark circles. However, many of you might prefer the new camera crowns.

Conclusion
In comparison to the S24 Ultra, Samsung has refined the design and the grip comfort for Galaxy S25 users. The phone offers a larger screen at the same dimensions and reduced weight. Overall, it’s a substantial improvement over last year’s device.

Samsung Galaxy S25 Ultra running One UI 7 but has one big security flaw

Samsung’s latest offering, the Galaxy S25 Ultra, features cutting-edge hardware and a refined software experience with its Android 15-based One UI 7 pre-installed. However, with the excitement, there’s a significant concern after its launch.
Everyone loved the S25 Ultra’s speed, camera, and how well it works with One UI 7. But, there’s a big security problem that might spoil the fun.
In recently released February 2025 Android security patch details, Google disclosed a serious zero-day vulnerability that has been actively exploited. This vulnerability (which can be identified as CVE-2024-53104,) affects how Android devices handle video frames, potentially leading to memory instability that hackers could exploit. Google has encouraged all Android users to update their devices promptly to reduce this risk.
Unfortunately, the Galaxy S25 Ultra is still running on the December 2024 security patch, leaving it vulnerable to this known exploit. This is particularly important because, unlike previous updates, it was urgent due to the active exploitation of the vulnerability.
Not having the newest security update on my S25 Ultra put me and other users at risk without knowing about it. This shows how important it is to get software updates quickly, especially for phones that are supposed to be the best in security (Sorry Knox!) and user experience.
Samsung now needs to act fast. The company must send out a quick update to fix this security vulnerability. People bought this phone expecting it to be very safe, so Samsung should keep its promise by protecting it from known threats.
Samsung usually reacts quickly to these problems, but the company is slow this time with the S25 Ultra (the S24 users crying in the background), which is concerning to me. The South Korean company needs to not only fix the issue but also keep their customers clearly informed about security updates.

In the end, the Samsung Galaxy S25 Ultra is great, but this security problem is a big mark against it. Users should watch for updates and install them right away. Samsung needs to make this fix a priority to keep users safe and keep its top phone’s reputation intact.
I reached out to Samsung for the official response on this but didn’t receive any confirmation yet.

Samsung Galaxy S25 Ultra: Unboxing and First Impressions

Samsung Galaxy S25 Ultra is being delivered and we now have an unboxing and first impressions experience with this new flagship, which appears to be slightly different from the previous model.
S25 Ultra Unboxing
The retail box’s dimensions are identical to last year’s S24 Ultra and highlight the frame and the S-Pen with white outlines. The box includes:
- SIM ejector tool
- USB-C to USB-C cable
- A quick start guide
- Galaxy S25 Ultra
That’s typical Samsung flagship stuff.

S25 Ultra First Impressions
The first look at the device goes to its shape, specifically, its outline. The trimmed corners are the center of discussion, which stands different from the S24 Ultra. The Titanium Silverblue color is prominent in the frame and frosted in the back due to the rear glass.
The sides are flat and the Titanium has a texture that doesn’t slip out of the grip. Some people might argue that the phone looks similar to an iPhone but that illusion ends when you get a hold of this device.
Actually, it feels more like S24U with flat and round experience. That’s it. One major change in hands-on experience becomes certain with its round corner, sitting well on the palm.

As a S24 Ultra owner, I also experience weight differences, a plus point for this new S25 Ultra. The weight and the design would no longer matter if you put on a protective cover, which most of the consumers would do.
On the other hand, the S-Pen is all the same, it’s similar to the last version, except for the lapsed Bluetooth functionality.
The camera system has a makeover with those new bold rings on top of the lenses. However, the internals remain the same for main and telephoto cameras, while increasing ultra-wide angle to 50MP. A major overhaul in the camera app made it easy to navigate features while decluttering the viewport.

Furthermore, the new Snapdragon 8 Elite shows its impact on performance and the phone is providing fast response in every touch input on the screen. It is loaded with One UI 7.0 software out of the box with generative AI features, which might amuse some customers.
Conclusion
The initial impression on this device shows a descent upgrade from last year. With that said, we conclude the unboxing and hands-on experience with the Samsung Galaxy S25 Ultra but this flagship has a lot to explore, please stay updated with us for more detailed explorations.
