Samsung Galaxy M55s

The Samsung Galaxy M55s has a standard, non-folding form factor with dimensions of 163.9 x 76.5 mm and a slim 7.8 mm thickness, keeping its overall volume at around 97.8 cm³. It weighs 180 g, which sits in a typical range for a device of this screen size. The phone does not feature a rugged build and carries no water resistance rating, so it offers no certified protection against moisture or physical stress.

The Samsung Galaxy M55s features a 6.7″ OLED/AMOLED touchscreen with a 1080 x 2400 px resolution and a pixel density of 385 ppi, delivering a sharp and vibrant visual experience. The panel supports a 120Hz refresh rate and includes an Always-On Display mode, keeping basic information visible without fully waking the screen. It does not carry branded damage-resistant glass, nor does it support HDR10, HDR10+, or Dolby Vision, and there is no secondary screen present.

The Samsung Galaxy M55s is powered by the Qualcomm Snapdragon 7 Gen 1, built on a 4 nm process with an octa-core CPU configuration running at up to 2.4 GHz using big.LITTLE technology and supporting 8 threads with full 64-bit and multithreading capabilities. Graphics are handled by the integrated Adreno 644 GPU clocked at 600 MHz, with support for DirectX 12 and OpenGL ES 3.2. The chipset also integrates LTE and ARM TrustZone for hardware-level security. The device comes with 8 GB of LPDDR5 RAM running at 3200 MHz, expandable up to a maximum of 16 GB, alongside 256 GB of internal storage.

The Samsung Galaxy M55s features a triple rear camera system with sensors at 50, 8, and 2 MP and corresponding apertures of f/1.8, f/2.2, and f/2.4, backed by optical image stabilization and a CMOS sensor. Autofocus options include phase-detection and touch autofocus as well as continuous autofocus during video, though laser autofocus is absent. The main camera captures video at 2160p at 30 fps and supports slow-motion recording, while HDR10 and Dolby Vision recording are not available. Manual controls cover exposure, ISO, focus, and white balance, and additional shooting modes include burst, panorama, and timelapse, though RAW output and 360° panorama are not supported. A single LED flash is present on the rear, with no dual-tone or RGB flash option, and there is no front-facing flash. The front camera offers a 50 MP sensor at f/2.4 as a single-lens setup, positioned above the display rather than under it.

The Samsung Galaxy M55s runs Android 14 and includes a broad set of privacy controls, covering location access management, camera and microphone permissions, clipboard warnings, and app tracking blocking, though cross-site tracking blocking and Mail Privacy Protection are absent. The interface supports theme customization and dynamic theming, dark mode, an extra dim mode, widgets, and customizable notifications, while focus modes and app offloading are not available. Multitasking is covered through split-screen support and Picture-in-Picture, and users can take full-page scrolling screenshots and use a media picker for selective file sharing. On-device machine learning is present, alongside offline voice recognition, voice commands, Live Text selection from images, sharing intents, and device tracking. The system supports multiple user accounts and a child lock, but does not offer Wi-Fi password sharing, Quick Start, or the ability to function as a PC. OS updates are not delivered directly from the vendor.

The Samsung Galaxy M55s is equipped with a 5000 mAh non-removable rechargeable battery that supports 45W wired fast charging, and a charger is included in the box. A battery level indicator is present for monitoring charge status. Wireless charging is not supported.

The Samsung Galaxy M55s includes stereo speakers but omits a 3.5 mm headphone jack, so wired audio requires an adapter or USB-C headphones. On the wireless audio side, none of the high-quality codec options are supported — aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC are all absent. There is no built-in radio tuner either.

The Samsung Galaxy M55s supports 5G connectivity along with Wi-Fi 4, 5, and 6, and comes with a dual SIM configuration and a maximum download speed of 550 Mbit/s. It connects via USB Type-C, though the USB standard is version 2, and there is no HDMI output. Bluetooth 5.2 and NFC are both present, while ANT+ and DLNA certification are not supported. An external memory slot is available for storage expansion. For navigation, the device includes GPS with Galileo support, a compass, gyroscope, and accelerometer, but lacks a barometer, infrared sensor, heart rate monitor, and motion or optical tracking. Security is handled through a fingerprint scanner; 3D facial recognition and an iris scanner are not included, and no stylus comes in the box. Features such as crash detection, emergency SOS via satellite, and a built-in projector are also absent.

The Samsung Galaxy M55s includes a video light for use during video recording, while its display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
