Whether you’re a student, casual user, or someone looking for a secondary 5G phone, the Galaxy M55 promises to offer something for everyone. Read on to find out if this is the right smartphone for your needs or if better alternatives exist in the ever-competitive sub-$400 market.
The Samsung Galaxy M55 build quality
The Galaxy M55 5G doesn’t stray far from familiar territory in its exterior styling, and that conservatism works in its favor. The rear panel is dominated by a smooth matte surface that resists fingerprints and lends the phone a refined, understated look. A vertically aligned camera module echoes the aesthetic of Samsung’s flagship S-series, giving the M55 a premium vibe despite its plastic construction. While polycarbonate might not carry the “luxury” connotation of glass or metal, it contributes to the phone’s durability minor drops and scuffs leave little trace and keeps the overall heft in check. In hand, the finish feels pleasant to the touch, and the subtle curvature along the edges helps it sit comfortably in the palm without any sharp or unwieldy corners.
Measuring just 7.8 mm thick and tipping the scales at approximately 180 g, the M55 manages to balance a large 6.7-inch display and 5,000 mAh battery with surprising lightness. This thin profile makes one-handed use more feasible reaching the top of the screen requires just a slight stretch rather than an uncomfortable grip shift. Samsung offers the handset in two tasteful colorways – Light Green, which has a soft pastel tone that stands out without feeling garish, and Denim Black, a deep charcoal shade that pairs well with both casual and professional settings. Whether you slip it into a jacket pocket or cradle it during lengthy video calls, the M55’s combination of size and weight feels thoughtfully calibrated to everyday usage.
The right side of the Galaxy M55 houses a tactile power button that doubles as a fingerprint sensor, delivering reliable biometric unlocking without forcing you to hunt for a finicky under-display scanner. Just above it sits the volume rocker, which provides firm feedback with each press. Along the bottom edge, you’ll find a USB-C port for fast charging, a single downward-firing speaker grille, and a SIM tray that accommodates two nano-SIMs plus a microSD card. One notable omission is the 3.5 mm headphone jack a feature still valued by many budget-segment buyers which means wired audio enthusiasts will need a dongle or USB-C adapter. Despite that minor drawback, the overall hardware layout is clean, logical, and free of unnecessary frills.

The Samsung Galaxy M55 display quality
The Galaxy M55 5G features a stunning 6.7-inch Super AMOLED+ display with a Full HD+ resolution (2400 x 1080) and a 120Hz refresh rate, making it one of the best displays you can get in a mid-range phone. The screen offers vibrant colors, deep blacks, and sharp details that elevate everything from Netflix marathons to casual web browsing. With slim bezels and a center punch-hole camera, the viewing area feels expansive and immersive, ideal for both entertainment and productivity.
What sets the M55’s display apart is the smoothness and fluidity brought by the 120Hz refresh rate. Scrolling through social media feeds, switching apps, or navigating menus feels seamless and responsive. Whether you’re gaming or just flipping through photos, the high refresh rate adds a premium touch to the experience. Touch response is accurate and snappy, which further improves the overall interaction with the device.
Samsung’s AMOLED technology also shines in terms of brightness and color reproduction. The display remains legible even under direct sunlight, thanks to its excellent peak brightness levels. Colors are punchy without being oversaturated, and viewing angles are wide with minimal color shift. HDR support, though limited to HDR10, still enhances contrast and dynamic range when streaming compatible content. Overall, for watching videos, reading, gaming, or any visual task, the Galaxy M55’s screen delivers performance that easily outpaces most rivals in its price category.
Performance of the Samsung Galaxy M55
Under the hood, the Galaxy M55 5G is powered by the Qualcomm Snapdragon 7 Gen 1 processor, a 4nm chipset that brings improved power efficiency and respectable performance to the mid-range market.
It’s paired with 8GB of LPDDR4X RAM and 128GB or 256GB of internal storage (UFS 2.2), which can be expanded via a microSD card. In daily use, this setup handles multitasking, web browsing, and app usage with ease.
Gaming performance is solid for casual players. Titles like PUBG Mobile and Call of Duty: Mobile run smoothly at medium-to-high settings. Genshin Impact, a more demanding game, is playable at medium settings but with occasional frame drops. The device does warm up during long gaming sessions, though thermal throttling is minimal.
Software & User Experience
The Galaxy M55 5G ships with One UI 6.1 based on Android 14, and Samsung promises four years of OS updates and five years of security patches, which is excellent for a mid-range device.
One UI continues to be one of the most polished Android skins. It offers useful features like:
- Edge Panels
- Split-screen multitasking
- Samsung Knox Security
- Digital Wellbeing
- Smart Widgets
The software is clean and smooth, though it does come with some pre-installed apps and ads in the notification panel. Fortunately, most of these can be uninstalled or disabled.
Animations are fluid, app transitions are fast, and system-level optimizations make the overall experience highly satisfying. Samsung’s ecosystem also adds value if you own other devices like Galaxy Buds, Galaxy Watch, or a Samsung Smart TV.
Camera Performance
One of the standout features of the Samsung Galaxy M55 5G is its versatile 50MP triple rear camera setup, which includes a 50MP main sensor with Optical Image Stabilization (OIS), an 8MP ultra-wide camera, and a 2MP macro lens. The primary camera captures detailed and vibrant shots, especially in well-lit environments. Thanks to OIS, even slightly shaky hands don’t result in blurred photos, and low-light performance sees noticeable improvement compared to phones without stabilization. Colors are vivid, dynamic range is broad, and focus is snappy—making the M55 a reliable shooter for everyday photography.
The 8MP ultra-wide sensor adds flexibility when capturing landscapes, group photos, or tight indoor spaces. While it doesn’t match the sharpness of the main camera, it still produces decent results with natural colors and minimal distortion at the edges. However, details tend to drop in low light, and noise becomes more noticeable. It’s best used in daylight conditions where it can contribute meaningfully to the photography experience. The 2MP macro lens, as expected in this price segment, is more of a novelty. It works for very close-up shots but lacks sharpness and consistency, making it more suitable for casual experimentation than serious use.
On the front, the M55 surprises with a 50MP selfie camera, which delivers sharp, well-balanced selfies in good lighting. Portrait mode works reasonably well, with solid edge detection and background separation. Both the front and rear cameras support 4K video recording at 30fps, and video output is stable and colorful, aided by EIS and OIS. Overall, the M55’s camera setup covers the essentials and more, especially for users who prioritize sharp stills and high-res selfies. While it won’t replace a flagship for pro-level photography, it offers great value and versatility for its price range.
Battery Life & Charging
The 5,000mAh battery in the Galaxy M55 5G offers excellent endurance. With moderate use (browsing, video, calls, social media), the phone easily lasts 1.5 to 2 days.
Here’s how it performs across scenarios:
- Video streaming (Wi-Fi, 50% brightness): ~17 hours
- Gaming: ~6 hours
- Mixed use: ~8-9 hours of screen-on-time
The phone supports 45W fast charging, and while there’s no charger in the box (Samsung’s new standard), compatible third-party chargers work just as well. It can charge from 0–100% in about 65 minutes, and up to 50% in under 30 minutes.
Wireless charging is not available, but that’s expected at this price.
Connectivity & Extras
Connectivity is where the M55 5G really shines:
- 5G support (global and regional bands)
- Wi-Fi 6
- Bluetooth 5.2
- GPS/GLONASS/Galileo/QZSS
- NFC for contactless payments
- USB-C 2.0 port
It also includes stereo speakers with Dolby Atmos support, delivering clear and immersive sound. The in-display fingerprint sensor is responsive and accurate, and haptic feedback is decent though not premium.
Sadly, there’s no 3.5mm headphone jack, and no IP rating, which would have been nice but isn’t a deal-breaker at this price.
Pricing, Variants & Availability
As of Q2 2025, the Samsung Galaxy M55 5G is available in the following configurations:
- 8GB RAM + 128GB storage – $349 USD
It’s available in markets like India, Southeast Asia, the Middle East, and parts of Europe via Samsung’s online store, Amazon, and major offline retailers. Buyers can often find discounts, cashback deals, or bundled offers like discounted Galaxy Buds or free accessories.
Samsung also offers trade-in programs and EMI options, making the M55 even more accessible.
