Review

Samsung Galaxy A31 Revisited: A Solid Performer for the Everyday User

I've spent the better part of a week putting the Samsung Galaxy A31 through its paces, and it’s a phone that definitely has its strengths, especially considering its position in Samsung's expansive lineup. Coming in at a mid-range price point, it’s clearly targeting users who want a reliable daily driver without breaking the bank. My testing involved typical daily usage – browsing, social media, media consumption, some casual gaming, and of course, the all-important camera tests in various lighting conditions. My initial impression is that Samsung has focused on delivering a dependable experience in key areas, though some compromises are evident.

Market Context: Finding its Niche

The Galaxy A31 arrived at a time when the mid-range smartphone market was, and still is, incredibly competitive. Samsung has a vast portfolio, and the A31 slots in as a solid, if not particularly groundbreaking, option. It feels like a play for those who prioritize a good screen and battery life over outright performance. Samsung's strategy here seems to be about offering reliable features at a reasonable price, banking on their brand recognition and established ecosystem. The price point feels appropriate for what you get, but there are certainly compelling alternatives in this segment, something I’ll touch on later.

Design & Hardware: Familiar Feel, Minor Annoyances

Picking up the Galaxy A31, the first thing that strikes you is its familiar Samsung aesthetic. The "Prism Crush" finish on the back, while visually appealing, does indeed attract fingerprints like moths to a flame, as I quickly discovered. It's made of plastic, which is expected at this price, but it feels well-constructed and surprisingly solid. The slightly rounded edges make it comfortable to hold for extended periods, a definite plus. Despite housing a substantial 5000mAh battery, it doesn't feel overly bulky in hand, which is a testament to its design. Durability-wise, the plastic build should withstand everyday bumps and scratches reasonably well, though the lack of an official IP rating means you'll want to be cautious around water. The inclusion of a standard headphone jack is a welcome sight for those who haven't fully embraced the wireless earbud life.

Display: A Visual Treat

The 6.4-inch Super AMOLED display is undoubtedly one of the highlights of the Galaxy A31. As the human review rightly pointed out, the colors are vibrant and punchy, making media consumption a genuinely enjoyable experience. Binging videos on this screen was a pleasure, with excellent contrast and deep blacks that only AMOLED can deliver. While it lacks the high refresh rates found on some pricier models, I didn't find the standard 60Hz refresh rate to be a significant hindrance for everyday scrolling and usage. Gaming also looked good on this display, although the underlying performance does have its limitations (more on that later). Even under bright sunlight, I found the brightness to be adequate for most situations, making it practical for outdoor use.

Performance: A Capable Daily Driver, Not a Powerhouse

Under the hood, the MediaTek Helio P65 chipset is where some of the compromises become apparent. In my testing, the phone handled everyday tasks like browsing, social media, and messaging without any major hiccups. However, when pushed with more demanding tasks, like running multiple apps simultaneously or playing graphically intensive games, some lag and stuttering became noticeable. During gaming sessions with titles like PUBG Mobile, I had to dial down the graphics settings to maintain a smooth frame rate. The 4GB of RAM in the base model might feel a bit limiting for heavy multitaskers; opting for the 6GB variant would likely offer a smoother experience. Temperature management was decent; the phone didn't get excessively hot even during extended gaming sessions. It's worth noting that the Helio P65 is a 12nm chip, which is a bit dated compared to some of the more modern, efficient processors in this price range.

Camera System: Versatility with Caveats

The camera system on the Galaxy A31 is a versatile setup, offering a 48MP main lens, an 8MP ultrawide, a 5MP macro, and a 5MP depth sensor. In practice, the main camera performs admirably in good lighting conditions, capturing images with decent detail and accurate colors. That sunset photo mentioned in the human review? I can attest to that – vibrant colors are definitely within its capabilities. The ultrawide lens is useful for capturing wider scenes, though the image quality isn't as sharp as the main sensor, and there's noticeable distortion at the edges. The macro lens is a fun addition for close-up shots, but its 5MP resolution limits the level of detail you can capture. The 20MP front-facing camera takes respectable selfies, performing well in good light but struggling a bit in low-light scenarios, as was also noted. Video recording is capped at 1080p at 30fps, which is adequate for casual use but lacks the smoothness of 60fps and the higher resolution options available on some competitors. Compared to other phones in this price range, the camera system is decent, but it doesn't particularly stand out in any single area.

Battery & Charging: Endurance Champion

The 5000mAh battery is a standout feature of the Galaxy A31. In my testing, it consistently delivered all-day battery life with moderate to heavy usage. On lighter days, I even managed to stretch it into a second day, which is impressive. That GPS test during a hike mentioned earlier? Definitely relatable – the battery life instilled confidence even during extended use. The 15W charging, while not the fastest on the market, is acceptable. It takes a little over two hours to fully charge the phone from empty, which isn't blazing fast, but it's not painfully slow either. The power management seems well-optimized, contributing to the phone's excellent endurance.

Software: Familiarity with Limitations

The Galaxy A31 launched with Android 10 and Samsung's One UI 2.1. While the phone has received updates up to Android 12, the lack of further major updates is a point to consider. One UI offers a familiar and feature-rich experience, with plenty of customization options and Samsung's suite of apps. Daily usage was generally smooth, but as mentioned earlier, performance limitations can sometimes lead to slowdowns, especially when dealing with resource-intensive apps or multitasking heavily. The interface is generally intuitive and easy to navigate, making it user-friendly for both new and seasoned Android users.

Value Analysis: Who is this Phone For?

Priced in the mid-range category, the Samsung Galaxy A31 offers a compelling package for specific types of users. If you prioritize a vibrant AMOLED display and excellent battery life above all else, and you're not a heavy gamer or demanding user, this phone is definitely worth considering. It’s a reliable all-rounder for everyday tasks, media consumption, and casual photography. However, if top-tier performance, cutting-edge camera capabilities, or the latest software updates are crucial for you, then you might want to look at alternatives like some of the newer offerings from Xiaomi, Realme, or even some of Samsung’s own higher-end A-series devices. These often offer better performance or features at a similar price point.

Conclusion: A Dependable Choice with Clear Strengths

The Samsung Galaxy A31 is a solid mid-range smartphone that excels in providing a great viewing experience and long-lasting battery life. While it may not win any awards for raw performance or camera innovation, it gets the fundamentals right for the average user. If you're looking for a dependable phone for everyday use, enjoy watching videos, and need a battery that will comfortably get you through the day, the Galaxy A31 is a worthy contender. It's a balanced device that offers good value for its price, especially if you can find it at a discounted rate. Ultimately, it’s a testament to Samsung's ability to deliver a reliable and user-friendly experience in the competitive mid-range segment.
