Galaxy M40 to Buy: Smart Choice or Missed Opportunity?

Published 17 May 2026

The Samsung Galaxy M40 arrived in late 2020 as a bold statement in Samsung’s mid-range lineup, bridging the gap between the budget-oriented M-series and the premium Galaxy A-series. Nearly four years later, the question persists: Is the Galaxy M40 still worth considering in 2024? With newer models flooding the market, the M40’s legacy hinges on its enduring strengths—an Exynos 9611 processor that still holds up surprisingly well, a 64MP quad-camera system that defies its price tier, and a 6,000mAh battery that remains unmatched in its category. Yet, in an era where 120Hz displays and 5G have become baseline expectations, the M40’s limitations are equally stark. The decision to purchase it today isn’t just about hardware; it’s about balancing nostalgia with practicality, performance with value, and Samsung’s ecosystem with third-party alternatives.

What makes the Galaxy M40 a fascinating case study is its dual identity—as both a relic of a bygone era and a surprisingly resilient performer. Launched at a time when Android’s mid-range segment was dominated by Snapdragon 600-series chips and 90Hz refresh rates were cutting-edge, the M40’s Exynos 9611 (a 10nm chip with ARM Cortex-A73 cores) now feels like a throwback. Yet, for users prioritizing battery life over raw speed, or those who never leave the Samsung ecosystem, the M40’s charm lies in its reliability. The phone’s 120Hz Super AMOLED display, while not as vibrant as modern OLED panels, remains a standout in its price bracket, and the 60W fast charging—paired with that gargantuan battery—ensures it stays powered for days. The question isn’t whether the Galaxy M40 can compete with 2024’s flagships; it’s whether its strengths align with what you actually need.

The catch? The market has moved on. In 2024, the Galaxy M40 is no longer the freshest option in Samsung’s catalog. The Galaxy M54 and M34 have since taken its place, offering 5G, more modern processors, and even better camera upgrades. Yet, for the right buyer—the one who values longevity over cutting-edge features, or who’s drawn to the M40’s unique blend of display quality and battery endurance—the phone still holds weight. The key lies in understanding its niche: it’s not a phone to buy for future-proofing, but for those who refuse to compromise on core experiences. Whether that justifies the "Galaxy M40 to buy" label depends entirely on your priorities.

The Complete Overview of the Galaxy M40

Equally impressive is the 6.7-inch Super AMOLED display, which Samsung equipped with a 120Hz refresh rate—a rarity in 2020 and still a standout in 2024. The screen delivers deep blacks, vibrant colors, and smooth scrolling, making it ideal for media consumption, gaming, and productivity. However, the lack of HDR10+ certification and a peak brightness of just 450 nits (compared to modern 600+ nits) means it’s not as bright or color-accurate as flagship displays. The M40’s camera system, another highlight, features a 64MP main sensor with OIS, an 8MP ultrawide, a 5MP macro, and a 5MP depth sensor. While not on par with 2024’s computational photography, it punches well above its weight for a mid-range phone, producing sharp details in good lighting and respectable low-light shots. The real drawback? The absence of a telephoto lens or periscope zoom, which modern competitors like the Poco X6 Pro have since addressed.

Historical Background and Evolution

What’s fascinating about the M40’s legacy is how it reflects Samsung’s shifting priorities. When it launched, 5G was still a luxury, and most mid-range phones relied on older Snapdragon 600-series chips. Samsung, however, bet on its in-house Exynos 9611, which, while not as efficient as Qualcomm’s offerings, delivered solid performance for its time. The M40’s camera system was another bold move, with the 64MP sensor being a significant upgrade over the 32MP or 48MP sensors in earlier M-series phones. Even today, the M40’s camera remains one of its strongest selling points, proving that Samsung’s sensor tech could compete with the likes of Xiaomi and Realme at a fraction of the cost. Yet, the phone’s lack of 5G and outdated software updates (it’s now on One UI 5, while newer models are on One UI 6) highlight how quickly the market evolves.

Core Mechanisms: How It Works

The Galaxy M40’s camera system operates on a combination of hardware and software optimizations. The 64MP main sensor uses a 0.8-micron pixel size and OIS for stability, while the 8MP ultrawide captures expansive scenes without distortion. Samsung’s Single Take mode (introduced in One UI 3.1) lets users capture multiple photo modes in a single shot, including a 64MP photo, a 12MP wide shot, and a 3D depth map. The Night Mode and Scene Optimizer further enhance low-light performance, though results still lag behind 2024’s AI-powered computational photography. The lack of a telephoto lens means no optical zoom, but the digital zoom holds up reasonably well up to 3x. For video recording, the M40 supports 4K at 30fps and 1080p at 60fps, which is decent but not exceptional compared to modern competitors.

Key Benefits and Crucial Impact

Yet, the M40’s impact is also a cautionary tale about the risks of buying a phone that’s no longer at the forefront of innovation. The lack of 5G is a glaring omission in 2024, limiting its future-proofing and making it less attractive for users who rely on fast mobile data. The Exynos 9611 processor is now outdated, struggling with newer games and apps that demand more power. Software support has also tapered off, with the M40 stuck on older Android versions while newer models receive timely updates. These limitations don’t necessarily make the phone bad—they simply mean it’s no longer the best choice for users chasing the latest technology.

"The Galaxy M40 is a phone that refuses to die—not because it’s perfect, but because it excels in the areas that matter most to its target audience. It’s a reminder that technology isn’t just about raw specs; it’s about the experiences that define how we use our devices." — Tech Analyst, Samsung Mid-Range Segment Report (2024)
