Samsung Galaxy A55 5G

The Samsung Galaxy A55 5G has a physical footprint of 161.1 × 77.4 mm with a thickness of 8.2 mm and a total weight of 213 g, giving it a moderately sized, non-folding form factor. One of its notable design traits is its IP67 rating, which certifies it as waterproof against submersion under defined conditions, and it earns a French Repairability Index score of 8.4 out of 10, indicating a relatively repairable construction. It is not built to a rugged standard, but it can operate in environments reaching up to 40 °C, and its total volume comes in at approximately 102.25 cm³.

The Samsung Galaxy A55 5G features a 6.6″ OLED/AMOLED touchscreen with a resolution of 1080 x 2340 px and a pixel density of 390 ppi, delivering a sharp and vibrant visual experience. It runs at a 120Hz refresh rate backed by a 240Hz touch sampling rate, and its typical brightness of 1000 nits keeps content visible in a variety of lighting conditions. The display is covered by Gorilla Glass Victus for added scratch and impact resistance, and it supports both HDR10 and HDR10+ content, though Dolby Vision is not supported. An Always-On Display mode is available, there is no secondary screen, and Dolby Vision playback is absent from the feature set.

The Samsung Galaxy A55 5G is driven by the Samsung Exynos 1480 system-on-chip, built on a 4 nm process with an octa-core CPU arrangement running at 4 × 2.75 GHz and 4 × 2.05 GHz using big.LITTLE architecture with HMP support, all within a 5W TDP envelope. It pairs 12 GB of LPDDR5 RAM at 3200 MHz across four memory channels with a maximum bandwidth of 51.2 GB/s, 256 GB of internal storage, and expandable memory support up to 1024 GB. Graphics are handled by the integrated Xclipse 530 GPU clocked at 1300 MHz, with DirectX 12 and OpenCL 2.0 support, returning benchmark scores of 3831 on 3DMark Wild Life, 3907 on Wild Life Unlimited, 982 on Wild Life Extreme, and 460 on Steel Nomad. The chipset includes integrated LTE, supports 64-bit processing and multithreading across 8 threads, and carries a 4 MB L3 cache. In CPU benchmarks, it scores 1173 single-core and 3534 multi-core on Geekbench 6, while the AnTuTu score sits at 713,393 and PCMark Work 3.0 returns a performance result of 13,151 alongside a battery endurance score of 808 minutes.

The Samsung Galaxy A55 5G features a triple rear camera system with sensors at 50 MP (f/1.8), 12 MP (f/2.2), and 5 MP (f/2.4), all using CMOS technology, with optical image stabilization on the main lens and a maximum ISO sensitivity of 3200. Autofocus options include phase-detection and touch autofocus for stills, as well as continuous autofocus during video recording, though laser autofocus is not present. The rear system can record video at up to 2160p at 30 fps and supports slow-motion recording, while HDR mode, burst shooting, timelapse, and in-camera panoramas are all available; HDR10 and Dolby Vision recording are not supported, and there is no optical zoom. Manual controls extend to exposure, ISO, focus, and white balance, but manual shutter speed and RAW shooting are absent, and the single LED flash has no dual-tone or RGB capability. On the front, a single-lens 32 MP camera with an f/2.2 aperture handles selfies — it sits in a standard position rather than under the display, has no dedicated flash, and carries a DxOMark Mobile score of 108.

The Samsung Galaxy A55 5G runs Android 15 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, and camera and microphone access management, though Mail Privacy Protection and cross-site tracking blocking are not available. On the customization side, it supports dark mode, dynamic theming, theme customization, widgets, and focus modes, while productivity is aided by split-screen multitasking, Picture-in-Picture, full-page scrolling screenshots, a media picker, sharing intents, and the ability to play games while they are still downloading. The OS also incorporates on-device machine learning, offline voice recognition, voice commands, Live Text for selecting text from images, customizable notifications with granular permission controls, and a battery health check tool. Multi-user support, a child lock, app offloading, an extra dim display mode, and device position tracking round out the feature set, though Wi-Fi password sharing, Quick Start, and the ability to use the phone as a PC are absent. OS updates are not delivered directly from the vendor, and the platform is noted as free and open source.

The Samsung Galaxy A55 5G houses a 5000 mAh rechargeable battery with a rated battery life of 57 hours, and it supports 25W fast charging over a wired connection, though no charger is included in the box and wireless charging is not supported. The battery is non-removable and features a battery level indicator, along with an ultra power-saving mode that can extend usage when charge runs low. Overall power management is further assisted by the availability of this reduced-function mode, making the most of the available capacity during extended use.

The Samsung Galaxy A55 5G includes stereo speakers and a triple microphone setup, but omits a 3.5 mm headphone jack, so wired audio requires an adapter or USB-C headphones. There is no radio tuner, and the device does not support any high-resolution Bluetooth audio codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC are all absent, limiting wireless audio to standard Bluetooth transmission.

The Samsung Galaxy A55 5G supports 5G cellular connectivity alongside Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6 (802.11ax), and accommodates two physical SIM cards plus one eSIM slot, offering flexible carrier options. Wireless connectivity is further covered by Bluetooth 5.3 and NFC, while wired connections go through a USB Type-C port running at USB 2.0 speeds; HDMI output is not available. Download speeds reach up to 3790 Mbit/s and upload up to 1280 Mbit/s, and an external memory slot is present for storage expansion. On the sensor side, the device includes a fingerprint scanner, GPS with Galileo support, a gyroscope, accelerometer, and compass, though there is no barometer, infrared sensor, heart rate monitor, iris scanner, or 3D facial recognition. Features such as ANT+, DLNA certification, crash detection, emergency satellite SOS, motion tracking, optical tracking, and a built-in projector are all absent, and no stylus is included in the box.

The Samsung Galaxy A55 5G includes a video light for illuminating video recording, while its display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
