Samsung’s latest M–series models—the M55 and M15—deliver flagship-inspired styling and solid specs at accessible price points. While cost reductions are inevitable, the M55 bucks tradition by introducing features never before seen in the M line, including a Snapdragon processor, up to 12GB of RAM, and 45W wired fast charging.
The Galaxy M55 borrows the three–camera layout of higher-end Samsungs but uses a durable plastic construction with a frosted matte finish to avoid fingerprints and give it a premium look and feel.
Its slender 7.8 mm profile and light 180 g weight make it one of the slimmest M-series phones yet, and a gentle curve in the back panel ensures a secure, comfortable grip.
Because of its sturdy plastic body and matte back, you won’t need a case to prevent smudges or accidental drops, and the metallic-finish frame houses slightly thicker, easy-to-press buttons for improved usability.
Available in a reflective Light Green or subtler Dark Blue, the M55 also features narrowed display bezels and a hybrid SIM tray that can hold two nano-SIMs or one nano-SIM plus a microSD card (up to 1 TB).
The Galaxy M55 sports Samsung’s signature Super AMOLED Plus panel, delivering punchy colors, deep contrast, and outstanding clarity. With a 1,000 nit peak brightness and Vision Booster technology, it stays highly readable even under bright sunlight. While very dark video scenes might lose a touch of detail, everyday content and outdoor viewing remain crisp and vibrant—just as you’d expect from Samsung’s best AMOLED effort in an M-series device.
Performance and Software
Hardware Smoothness
First M-series phone with a Qualcomm Snapdragon processor paired with up to 12 GB of RAM
Though the chipset is two generations old, daily use feels fluid: apps open quickly, multitasking is seamless, and graphically demanding games run in optimized modes without hiccups
The device warms slightly after extended gaming sessions but never becomes uncomfortably hot
Touch responsiveness stays snappy, making fast-action titles and UI navigation equally effortless
Cost-Performance Balance
Samsung’s choice of an older SoC helps keep the price down, freeing up resources for features, security, and long-term support
Promised upgrades: Four major Android releases (vs. three years on most rivals) and four years of security patches
Unique M-series perks: Samsung Wallet with tap-to-pay, and Knox Vault hardware/software protection to safeguard credentials and sensitive data
Software Features (One UI 6.1 on Android 14)
Image Clipper: Long-press any subject to extract and paste it into other apps
Object Eraser: Remove unwanted elements from photos with a few taps
Voice Focus: Prioritize your voice over background noise during calls
Secure Folder: Lock away private files, apps, and media behind a fingerprint or PIN
Lock-Screen Customization: Choose from new clock styles, fonts, colors, and add widgets directly to the lock screen
Wallpapers & Themes: Access Samsung’s built-in theme store, generative AI wallpaper options, and a rich library of presets
One-Hand Operation: Shrink the UI for easier single-handed use on a large display
Edge Panel: Swipe in shortcuts, app pairs, and quick tools from any screen
These software refinements and security layers, combined with Samsung’s upgrade commitment, make the Galaxy M55 feel far more premium than its price tag suggests.
Samsung Galaxy M55 Camera
Samsung has significantly revamped the M55’s imaging hardware:
50 MP main sensor (f/1.8) with OIS and Nightography for brighter, cleaner low-light shots
8 MP ultra-wide lens (123° field of view)
2 MP macro module
50 MP front-facing camera
In real-world shooting, photos look far more natural than previous M-series efforts—colours are balanced and sharpening restrained. Bright-sun scenes can still show clipped highlights or overly aggressive HDR, but indoor images retain fine detail even under dimmer lighting. Nightography and large-pixel technology let the M55 gather extra light, producing bright, low-noise photos after a slightly longer capture delay. Portrait mode generally nails background separation, though complex edges (like jewellery links or flower petals) sometimes blur. Selfies impress under moderate lighting, with softening only when illumination falls very low—an acceptable trade-off at this price point.
Battery & Charging
The M55 keeps its 5000 mAh cell but upgrades to 45W wired charging—enough to refill from 0 to 50 percent in under 25 minutes. Until now, Samsung had reserved that speed for its Ultra-tier flagships, so seeing it on an M-series phone marks a major step forward and bodes well for future mid-range models.
Samsung Galaxy M15
Alongside the M55, Samsung introduced the more affordable Galaxy M15:
6.5 in Super AMOLED display with a 90Hz refresh rate
Headphone jack
Massive 6000 mAh battery
Four generations of OS updates plus five years of security patches
