The Samsung Galaxy S25 is a series of high-end Android-based smartphones manufactured, developed, designed and marketed by Samsung Electronics as part of its flagship Galaxy S series. They collectively serve as the successor to the Galaxy S24 series. The first three models were announced on January 22, 2025, at the Samsung's Galaxy Unpacked event in San Jose, California, and were released on February 7, 2025. Two additional models were also launched in the series: the Galaxy S25 Edge, was revealed at the end of the first event, then launched at Galaxy Unpacked on May 13, 2025, and later released on May 30; and Galaxy S25 FE was launched on September 4, 2025 and was released to the market two weeks later on September 19, 2025. On February 25, 2026, Samsung announced the successor to the Galaxy S25 series, the Samsung Galaxy S26 series.
History
Galaxy S25 Before its official announcement, media speculation primarily centered on reports that the S25 would lack the Galaxy Note design, which the renders show a fully flat sides, with smaller dimensions, and a video was posted showing a working Galaxy S25 Ultra, with rounded edges. The video also shows that it is running One UI 7, showing a revamp of the One UI experience, the colors for the phones were also leaked, and accessories for the phone were also reportedly being supplied to Dbrand. The S25's design was officially teased in an Italian poster on December 22, 2024, which shows a rounded design. A promotional trailer for the phone was leaked online in January 2025, showing a light blue Galaxy S25 Ultra, displaying a set of quick tiles at the bottom of the lock screen, and swiping through those showcases a “Morning brief” button. Marketing material for the phones were leaked, a week before the official launch, confirming the new AI features.
Announcement Samsung officially unveiled the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra, during a press release at Samsung's Galaxy Unpacked event in San Jose, California, on January 22, 2025.
Galaxy S25 Edge The name of the phone was originally presumed to be the Galaxy S25 Slim due to it being 6-7mm thin. However, leaks around the time of Samsung's Galaxy Unpacked event in January 2025 revealed the title of the phone to be named the Galaxy S25 Edge, because it is the thinnest smartphone ever. More media speculation primarily centered on reports that the Galaxy S25 Edge would be using a Qualcomm Snapdragon 8 Elite processor. Samsung claims that the chipset would help in offering long-lasting battery life on its ultra-slim phone. After months of rumors and speculation, during a press release at the Samsung Unpacked event on May 13, 2025, Samsung officially announced a fourth model, the Galaxy S25 Edge, which features a 6.7-inch (17 cm) display, and measures 1.5mm thinner than the Galaxy S25+, and almost 2.5mm thinner than the Galaxy S25 Ultra.
Lineup The Galaxy S25 lineup includes five models: Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, Galaxy S25 Edge and the Galaxy S25 FE. The S25 Edge, which is the thinnest Samsung phone since the Galaxy A8 (2015) and U100 (2007), is the first Edge model since the S7 Edge and the first Galaxy S phone since the S10e to only have two rear cameras. In addition to manufacturing the Galaxy S25 Ultra in Vietnam and India, it was also officially manufactured in Egypt and launched in the local market through official stores and agents. It was exported to the Gulf and North African countries as a first step towards exporting this product.
Dimensions The Galaxy S25 features a flat 6.2 in (160 mm) display. The Galaxy S25+ offers similar internal hardware with a larger 6.7 in (170 mm) display. The Galaxy S25 Ultra includes a 6.9 in (180 mm) display, a larger frame compared to its predecessor, and rounded corners that align more closely with the design language of the Galaxy S series. The Galaxy S25 Edge, a new addition to the series, also has a 6.7-inch (17 cm) display and is the thinnest and most compact model in the lineup, at 5.8 mm (0.23 in) thick. Across the line-up, weights range from 162 g (Galaxy S25) to 218 g (Galaxy S25 Ultra). While the S25 and S25+ have dimensions similar to their S24 counterparts, the S25 Ultra includes design adjustments, and the S25 Edge is distinguished by a thinner chassis.
Performance The Galaxy S25 series (except the FE model) is powered by the Snapdragon 8 Elite chipset. Unlike previous Galaxy S generations that used different chipsets by region, the Snapdragon 8 Elite is used uniformly across all global variants. Manufactured using a 3 nm process, the chipset features an octa-core CPU with two high-performance Oryon cores clocked up to 4.47 GHz and six efficiency cores running at 3.53 GHz. Its Adreno 830 GPU provides hardware-accelerated graphics and AI-related processing, enabling performance in resource-intensive applications. All models in the lineup feature a redesigned vapor chamber cooling system that helps dissipate heat produced by the chipset during heavy workloads. While select models share the same processor, the vapor chamber size and design differ by device. The S25 and S25+ use chambers approximately 15% larger than those of the Galaxy S24 series, the S25 FE has a 10% larger vapor chamber for cooling, the S25 Edge adopts a vapor chamber with a thinner and wider surface area, and the S25 Ultra integrates a chamber about 40% larger with additional material layers for heat dissipation.
Connectivity The Galaxy S25, S25+, S25 Ultra, and S25 Edge all offer the same eSIM functionality in their respective regions. International variants support dual Nano-SIM slots along with dual eSIM profiles. U.S. models include a single Nano-SIM slot with dual eSIM support, while Chinese versions retain the traditional dual Nano-SIM configuration without eSIM capability.
Design
The S25 and S25+ smartphones have an aluminum body and a glass back, similar to the design of their predecessors. Both the S25 and S25+ use Gorilla Glass Victus 2 for both the front display and rear glass panel. They come in five standard colors: Icy Blue, Mint, Navy, Silver Shadow, and Blue Black, having previously been available exclusively on Samsung's website alongside Pink Gold and Coral Red, which were removed from the exclusive list due to higher demand than anticipated. The S25 Ultra has a titanium body and a glass back, similar to the S24 Ultra; however, the phone features rounded corners, unlike the S24 Ultra's squared corners. Additionally, the S25 Ultra uses Gorilla Glass Armor 2 for its front display and rear panel, improving durability and reducing glare. The S25 Ultra comes in four standard colors: Titanium Silver Blue, Titanium Black, Titanium White Silver, and Titanium Grey, with Titanium Jet Black, initially an exclusive option, added to the roster later due to high demand. The S25 Ultra comes in two additional colors that are only available through Samsung's online website: Titanium Jade Green and Titanium Pink Gold.
The S25 Edge is available in three colors: Titanium Icy Blue, Titanium Silver, and Titanium Jet Black.
Specifications
Display The Galaxy S25 series features a Dynamic LTPO AMOLED 2X display across all models with HDR10+ support and a 120 Hz refresh rate, reaching up to 2600 nits. Each device also includes an ultrasonic in-screen fingerprint sensor, except for the S25 FE, which uses an optical in-screen fingerprint sensor. The S25 Ultra uses Corning Gorilla Armor 2, the S25 Edge uses Corning Gorilla Glass Ceramic 2 on the front, and the S25 and S25+ use Gorilla Glass Victus 2. According to Corning, the Gorilla Armor 2 on the S25 Ultra offers enhanced durability, with over four times greater scratch resistance than conventional lithium-aluminosilicate cover glass and features anti-reflective properties to reduce surface glare. Laboratory tests further reported that it can withstand drops of up to 2.2 metres onto a surface simulating concrete, while comparable glass-ceramic materials reportedly failed from 1 metre.
ProScaler ProScaler is an AI-based upscaling technology embedded in the Galaxy S25+, S25 Edge, and S25 Ultra models. Leveraging Samsung's ProVisual Engine, ProScaler is designed to enhance lower-resolution content by upscaling it to higher resolutions, improving how it appears on high-resolution displays. The ProScaler feature is optimized for QHD+ resolution (3120×1440 pixels), which provides a higher pixel density than FHD+. QHD+ allows ProScaler's AI-based upscaling to produce consistent visuals.
Camera
The Galaxy S25 and S25+ each feature a triple rear camera system consisting of a 50 MP wide-angle (main) camera, a 12 MP ultra-wide camera with a 120° field of view, and a 10 MP telephoto camera offering 3× optical zoom. The Galaxy S25 Ultra features a quad camera setup, including a 200 MP wide-angle camera, a 50 MP ultra-wide camera, a 10 MP telephoto camera with 3× optical zoom, and a 50 MP periscope telephoto camera with 5× optical zoom. The Galaxy S25 Edge features a dual-camera system with a 200 MP wide-angle sensor and a 12 MP ultrawide sensor, but no telephoto lens. The Galaxy S25 FE, meanwhile, features a triple rear camera system consisting of a 50 MP wide-angle (main) camera, a 12 MP ultra-wide camera with a 120° field of view, and a 8 MP telephoto camera offering 3× optical zoom. All models in the series feature a 12 MP front-facing camera (f/2.2) for selfies and video calls. Under the ProVisual Engine—a Samsung Galaxy AI imaging system—the Ultra model includes image processing features such as adaptive scene optimization and noise reduction for photography and videography. The S25 Ultra further introduces a Quad Tele System, allowing four distinct optical zoom levels (2×, 3×, 5×, and 10×), which provides flexibility in framing subjects at varying distances. All models support pixel-binning techniques and include a Super Steady video mode for stabilization. All models in the series can record video at up to 8K resolution at 30 fps, delivering high-resolution video capture across the lineup.
Batteries The Galaxy S25 models have similar battery capacities to the S24 series. However, the S25 Edge has a smaller battery than the S25+ due to its decreased thickness. The S25 and S25 Edge support wired charging at up to 25 W, whereas the S25+, S25 Ultra and S25 FE support 45 W charging. The S25 Ultra can reach up to 65% charge in around 30 minutes with a 45 W adapter, while the S25 and S25 Edge reach about 50% in the same time with a 25 W adapter. All five support Qi2 inductive charging up to 15 W, and can charge other Qi-compatible devices wirelessly using battery power.
Memory and storage Unlike previous generations, all Galaxy S25 models launched with 12 GB of RAM. The S25 starts at 128 GB of storage, while the other three models start at 256 GB. The S25 Edge also comes standard with 12 GB of RAM and does not offer configurable RAM options. However, in the markets of South Korea, the People's Republic of China, Hong Kong, and the Republic of China (known as Taiwan), a 16 GB RAM option exists for certain Galaxy S25 Ultra models. For South Korean models, Titanium Jetblack phones with 1 TB of storage come with 16 GB of RAM. For the other three markets, regardless of color choice, the 1 TB storage option comes with 16 GB of RAM. All models in the series use UFS 4.0 flash storage and LPDDR5X memory, which are supported by the Snapdragon 8 Elite platform. These technologies provide higher bandwidth and improved power efficiency compared with previous-generation mobile memory and storage standards.
Connectivity All models in the Galaxy S25 series, except the S25 FE, support 5G connectivity, Wi-Fi 7, Bluetooth 5.4, NFC, and USB Type-C 3.2 for data transfer and charging. Ultra-Wideband (UWB) is supported only on the S25+, S25 Edge, and S25 Ultra models. The S25 FE only supports Wi-Fi 6E.
Software
The Galaxy S25, S25+, S25 Ultra, and S25 Edge were the first to be released with Android 15 and One UI 7. In contrast, the S25 FE was released subsequently with Android 16 and One UI 8. Like its predecessor, Samsung has promised 7 years of OS and security updates to the S25 series of phones (support ending within 2032). The devices are additionally shipped with Galaxy AI, Samsung's suite of artificial intelligence features. As a relatively new technology, it has received updated capabilities in the S25 series.
Reception Whilst iterative, the S25 was reviewed as a well-balanced phone, and one of the best of 2025, with only its AI receiving (as a new technology) some caveats. It was also praised as being the most compact of Android's high-end phones and for its ease of repair and usage of recycled materials.
S Pen controversy With the release of the S25 Ultra, Samsung opted to remove the Bluetooth functionality in its trademark S Pen, a feature added to the stylus with the Galaxy Note 9 in 2018. Samsung sought to remove the Bluetooth features between the phone and the pen as a cost-saving measure, claiming they were used by less than 1% of Galaxy users. Among the functions lost in are remote camera control, air actions, and several in-app features for programs such as PowerPoint or the native Gallery app.
Issues Many S25 Ultra users had experienced battery drain and overheating after installing the July 2026 security update. Users had traced the issue over to WhatsApp where the backup process would get stuck during the installation of the update.
