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 successor to the Galaxy S23 series. The phones were announced on January 17, 2024, at the Galaxy Unpacked event in San Jose, California and subsequently released on January 31, 2024. The S24 FE was announced on September 26, 2024, and was released on October 3, 2024. They were succeeded by the Galaxy S25 series announced on January 22, 2025.
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. The Galaxy S24 Ultra features a flat 6.8-inch (173 mm) display, with sharp edges, distinct from its base model counterpart. The S24 and S24+ phones are powered by Snapdragon 8 Gen 3 in the U.S., Canada, 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. Conversely, the S24 FE comes with an underclocked variant of the Exynos 2400 called the Exynos 2400e in every market including North America.
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.
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.
The Galaxy S24 and S24+ have a 50 MP wide sensor, a 10 MP 3x telephoto sensor and a 12 MP ultrawide sensor. The S24 Ultra has 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 all three models.
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 only charges at 25 watts, while the S24+ and S24 Ultra charge up at 45 watts charging.
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). All models support 5G mmWave exclusively in the US.
The Galaxy S24 phones feature 4,800 MT/s LPDDR5X memory and Universal Flash Storage 3.1 with 128 GB or version 4.0 with 256 GB and above.
The Galaxy S24 phones were released with Android 14 with Samsung's One UI 6.1 user experience. Samsung has promised 7 years of security patches and OS upgrades.
All phones use Google's on-device Gemini Nano, already used by their own Pixel 8 Pro and their Pixel 9 series.
Starting with the Galaxy S24 and all future Samsung Galaxy smartphones and tablets, 32-bit applications are no longer supported. Devices that were released prior to the Galaxy S24 will continue to support 32-bit apps.
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.
