The Samsung Galaxy S24 is a series of high-end Android-based smartphones developed, manufactured, and marketed by Samsung Electronics as part of its flagship Galaxy S series. They collectively serve as the successors to the Galaxy S23 series. The first three smartphones (Galaxy S24, Galaxy S24+, and the Galaxy S24 Ultra) were announced on January 17, 2024, at the Galaxy Unpacked event in San Jose, California, and they were released in the United States and Europe on January 31, 2024. The Galaxy S24 FE was unveiled at Samsung's Galaxy Unpacked event on September 26, 2024, alongside the Galaxy Tab S10 series, and released on October 3, 2024. The Galaxy S24 series was succeeded by the Galaxy S25 series, which was announced on January 22, 2025.
History The successor to the Galaxy S23 series was the subject of months of speculation about its development and launch. Reports as early as July 2023 suggested Samsung would switch to a titanium frame, following the inclusion of a titanium frame on the iPhone 15 Pro. Multiple reports of the Galaxy S24 series were known, where the phones could arrive as early as January 2024, to pictures showing the actual Galaxy S24 Ultra, and alleged specs and renders of the supposed devices were leaked ahead of launch. A week before its launch, it was reported that the Galaxy S24 series would get seven years of major OS upgrades, which was first introduced with the Pixel 8 series.
Lineup
Dimensions
The Galaxy S24 series includes four devices, which share the same lineup and screen sizes as the previous Galaxy S23 series. The flagship Galaxy S24 features a flat 6.2-inch (155 mm) display. The Galaxy S24+ features similar hardware in a 6.7-inch (168 mm) form factor.

Performance The S24 and S24+ phones are powered by Snapdragon 8 Gen 3 in North America and in East Asia (China, Macau, Hong Kong, Taiwan, and Japan), while a Exynos 2400 is used in the rest of the world. The S24 Ultra is equipped with the Snapdragon 8 Gen 3 in every market. In contrast, the S24 FE comes with an underclocked variant of the Exynos 2400 called the Exynos 2400e in every market including North America. A re-released version of the smaller S24 with the Snapdragon 8 Gen 3 processor was released exclusively in India in September 2025 (previously, the same device sold in India in January 2024 have the Exynos 2400 chipset).
Design The Galaxy S24 and S24+ have aluminum and matte glass versions and are available in four standard colors: Amber Yellow, Marble Gray, Cobalt Violet, and Onyx Black, with three additional colors available only through Samsung's website: Jade Green, Sapphire Blue and Sandstone Orange. The S24 Ultra features titanium versions of these colors. The Galaxy S24 FE has a limited set of 5 colors called Blue, Graphite, Gray, Mint, and Yellow.
Specifications
Display The Galaxy S24 and S24+ use a "Dynamic AMOLED 2X" display with HDR10+ support, 2600 nits of peak brightness, LTPO backplane, "dynamic tone mapping" technology, and Corning Gorilla Glass Victus 2. The Galaxy S24 FE has 1900 nits of peak brightness and LTPS backplane. All models use an ultrasonic in-screen fingerprint sensor, except the S24 FE which uses an optical in-screen fingerprint sensor. The S24 series uses a variable refresh rate display with a range of 1 Hz or 24 Hz to 120 Hz, except the S24 FE which has a range of 60 Hz to 120 Hz. The Galaxy S24 Ultra, in addition to the features of the S24+, uses Corning Gorilla Glass Armor glass on its display, but it drops the curved edges seen in the Galaxy S23 Ultra & Galaxy S22 Ultra.
Camera The Galaxy S24 and S24+ each feature a triple rear camera system consisting of a 50 MP wide sensor, a 10 MP 3x telephoto sensor and a 12 MP ultrawide sensor. The S24 Ultra features a quad camera setup, including a 200 MP wide sensor, 50 MP 5× periscope telephoto sensor, 10 MP 3x telephoto sensor, and a 12 MP ultrawide sensor. The front camera uses a 12 MP sensor on the Galaxy S24, S24+, and S24 Ultra. The Galaxy S24 FE feature a triple rear camera system consisting of a 50MP wide sensor, a 8 MP 3x telephoto sensor, and a 12MP wide sensor. The front camera of the Galaxy S24 FE is a 10MP sensor.
Batteries The Galaxy S24, S24+, S24 Ultra, and S24 FE contain internal 4,000 mAh, 4,900 mAh, 5,000 mAh, and 4,700 mAh Li-ion batteries respectively. The S24 and S24 FE charge at only 25 watts; the S24+ and S24 Ultra, at 45 watts.
Memory and storage Just like its predecessor, it continued to offer similar storage options, with the Galaxy S24+ and Galaxy S24 Ultra now being sold in a sole 12 GB RAM option.
Connectivity The Galaxy S24, S24+, and S24 FE support 5G SA/NSA/Sub6, Wi-Fi 6E, and Bluetooth 5.3 connectivity, while the Galaxy S24 Ultra additionally supports Wi-Fi 7 and ultra-wideband (UWB). The S24+ also supports UWB. All models support 5G mmWave exclusively in the United States.
Software The Galaxy S24 phones come with the Android 14 operating system with One UI 6.1 pre-installed, which was the latest version of Android available at the time of its release. The Galaxy S24 series are the first phones to support 7 years of OS and security updates, making Samsung the second among Android device manufacturers to offer 7 years of support (the first to do so was Google with the release of Pixel 8 lineup). This mean software updates will end within 2031. Starting with the Galaxy S24, 32-bit ARMv7 applications are no longer supported due to restrictions in the SoC. Other Galaxy devices (except watches) from 2024 onwards will also not support 32-bit ARMv7 apps.
Galaxy AI Galaxy AI is Samsung's branding for its artificial intelligence features introduced with the Galaxy S24 series, integrating generative AI capabilities into One UI. The platform combines on-device processing with cloud-based AI services to support communication, productivity, and multimedia functions. In mainland China, the cloud partner is Baidu providing its Ernie model, while in international markets (including Hong Kong and Taiwan), the cloud partner is Google providing its Gemini Pro model. All models in the Galaxy S24 series use Google's on-device Gemini Nano, already used by their own Pixel 8 Pro and their Pixel 9 series.
Reception
S Pen burnt smell Some users noted the unpleasant smell of the Galaxy S24 Ultra's S Pen, likened to "burnt plastic". A moderator on Samsung's EU forums said the smell was a normal part of the pen's operation, and "isn't anything to be concerned about". This smell is likely from chemical reactions to the plastic shell of the S Pen, induced by the internal heat of the phone.
Issues Many S24 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.
