Samsung Galaxy A18 4G: Comprehensive Review
Introduction, specs, unboxing
Introduction
Let's be realistic: the Galaxy A18 4G isn't designed to steal the spotlight or dominate tech headlines. However, for those seeking an affordable Samsung device—perhaps as a carrier-bundled phone or a reliable handset for a less tech-savvy family member—it's a practical choice. While the flagship S-series captures the glamour, the budget-friendly A-series is what truly drives Samsung's massive volume in the global market.
The Galaxy A18 4G follows a familiar blueprint: delivering the essential features with a few strategic enhancements, all while keeping the cost low. At a glance, the entry-level 4G models of the Galaxy A family seem stagnant in terms of design. However, the transition from the MediaTek Helio G99 to Samsung's proprietary Exynos 1610 silicon may be more significant than it first appears.

It is important to note that this specific model is the 4G variant, which recently launched quietly across Europe. While the Galaxy A18 5G has not yet debuted, it is expected to arrive soon, likely powered by a Qualcomm Snapdragon processor. Some industry whispers suggest that chipset availability issues may have delayed its release, although Samsung has not officially confirmed a launch date.
For now, the A18 4G is available, and Samsung has largely stuck to its winning budget formula. That said, there are a few notable upgrades over the previous Galaxy A17 4G. While the chassis remains primarily plastic, the A18 4G now boasts an IP64 rating. While this improves dust resistance, users should remember that it only offers basic protection against water splashes.
The most intriguing change is the integration of the new Exynos 1610 chipset, which is currently unique to the Galaxy A18 4G.
Beyond that, the hardware is very familiar. You get a 6.7-inch Super AMOLED panel manufactured by Samsung, featuring a 90Hz refresh rate and the traditional teardrop notch for the selfie camera. Following the established A-series design, the side-mounted power button doubles as a capacitive fingerprint scanner. The aesthetics are characterized by substantial bezels—particularly the "chin"—and a vertical triple-camera array on the back. While there are three lenses, the utility of the 2MP macro sensor is questionable at best.
Powering the device is a 5,000mAh battery supporting 25W fast charging. The package is rounded out with standard connectivity and a microSD slot for expanded storage. On the software side, the phone runs One UI 9 based on Android 17. Perhaps the most impressive selling point at this price bracket is Samsung's commitment to providing up to six major OS updates, ensuring long-term viability.
Unboxing
The Galaxy A18 4G arrives in a lightweight, two-piece cardboard box. Samsung has leaned heavily into sustainability here; the packaging is entirely plastic-free, replacing traditional shrink wrap with two factory seal stickers. A cardboard insert holds the device securely, though a more robust protective layer over the screen would have been welcome. Nevertheless, the packaging is sufficient, and our unit arrived in pristine condition.
The eco-friendly approach extends to the printing, which utilizes soy-based inks. While many brands opt for monochrome designs for sustainable packaging, Samsung has included a color illustration that corresponds to the specific color of the device inside.
Inside the box, Samsung provides a modest selection of accessories: a white USB Type-C to Type-C cable (3A rated, lacking an e-marker chip) and a standard SIM removal tool. It is a lean package, aligning perfectly with current industry trends.
Design, build quality, handling
Aesthetics, Construction, and Ergonomics
Anyone familiar with Samsung's entry-level offerings from the last few years will recognize the design language here. While it's perhaps unfair to call it a "budget look"—given that Samsung constantly tweaks the formula—the Galaxy A18 4G retains several hallmarks of the series: the vertical camera layout, the teardrop notch, and the characteristic raised buttons on the right edge.
The latest evolution brings a flatter, more streamlined middle frame. Moving away from the softer curves found on older A-series devices, Samsung has embraced the current industry trend toward sharper lines. This is most evident in the aggressive corner radii, which extend to the display, resulting in more significant corner clipping than we've seen on previous models.
The raised section of the frame housing the volume rocker and power key remains a signature A-series trait. Elsewhere, the device attempts to mirror the premium S-series aesthetic; a prime example is the camera housing, which has returned to a unified "island" design rather than utilizing three distinct, floating modules.
Regarding the physical interface, the A18 4G sticks to a traditional layout. The buttons on the right side are ergonomically placed and provide a satisfying, tactile click.
Integrated into the power button is a capacitive fingerprint scanner. This technology has reached a high level of maturity, and the implementation here is both responsive and precise, performing flawlessly during our testing.
The left side of the chassis is largely devoid of features, save for the hybrid SIM and microSD slot. While Samsung has mastered a matte finish that mimics the look of metal, the frame is constructed from plastic, which eliminates the need for visible antenna bands.
Despite the prestige associated with metal, plastic remains a highly practical choice for smartphones. It is resilient, resists denting better than aluminum, and keeps the device lightweight. Weighing in at 196 grams, the Galaxy A18 4G is slightly heavier than the A17 4G, but it still feels manageable in the hand.
Completing the hardware tour, a discreet secondary microphone is located on the top edge. The bottom edge houses the primary microphone, a downward-firing speaker, and the USB Type-C port. Notably, the 3.5mm headphone jack is absent—you would have to go as far back as the Galaxy A15 to find one in this lineup. As expected, there is no IR blaster.
The color palette is conservative, with the A18 4G available in Black, Gray, and Light Blue. Regional naming may vary; for instance, our specific unit was labeled as "Silver" on the packaging.
The overall aesthetic is muted and professional rather than flashy. We appreciate Samsung's attention to detail in color-matching the chassis; the middle frame and the ring surrounding the camera island are finished in complementary shades that blend seamlessly with the rear panel.
A plastic chassis isn't synonymous with a cheap feel; the Galaxy A18 4G remains impressively rigid, exhibiting no noticeable flex or hollow spots. In a positive move, Samsung has bumped the ingress protection to an IP64 rating, a slight upgrade over the IP54 found on the previous Galaxy A17 4G. While this shift primarily enhances dust resistance rather than waterproofing, the A18 4G features a robust rubber gasket on the SIM tray, suggesting it could potentially withstand a quick plunge into fresh water despite the lack of a formal immersion rating. With its IPX4 water resistance, the device is designed to handle light splashes and rain without issue.
However, there is a concerning regression in durability regarding the display. In a surprising downgrade, the A18 4G utilizes Gorilla Glass 3, replacing the superior Gorilla Glass Victus+ seen in last year's iteration. This shift to an older, more cost-effective glass has tangible consequences: while Victus+ is rated to survive drops of up to 2 meters onto hard surfaces, Gorilla Glass 3 is only rated for 1 meter. Furthermore, Victus+ boasts up to four times the scratch resistance of its predecessor, making this a disappointing trade-off for the consumer.

Display
Samsung maintains a predictable hierarchy with its screen technology, leveraging its position as a global leader in panel manufacturing. While the premium S-series handsets boast "AMOLED 2X" displays, the Galaxy A lineup typically utilizes "Super AMOLED." Though this branding was once reserved for flagships years ago, it has since become the standard for Samsung's mid-range and entry-level offerings.
This "trickle-down" approach doesn't imply the use of obsolete hardware. In fact, we often observe incremental generational refinements. The Galaxy A18 4G is a prime example; while the specifications remain familiar—a 90Hz Super AMOLED panel with a 1080 x 2340 resolution, a 19.5:9 aspect ratio, and a pixel density of roughly 385 ppi—the actual visual experience feels upgraded. Our review unit exhibited a noticeable boost in sharpness, contrast, and color vibrancy compared to previous devices in this category.
In terms of measurable performance, the A18 4G's luminosity aligns with other recent AMOLED-equipped A-series models, easily outpacing budget LCD options like the Galaxy A07 4G. In automatic mode, Samsung targets approximately 800 nits; our testing yielded just under 800 nits on a 75% window in bright conditions. When pushed to a smaller 10% window, the panel peaked at around 1,100 nits. While not industry-leading, it remains entirely functional for outdoor use.
However, the A18 4G trails behind many of its rivals in peak brightness. Even within Samsung's own ecosystem, the Galaxy A37 outperforms it. Higher-tier models like the Galaxy A57, which features a "Super AMOLED+" panel and HDR10+ certification, offer significantly more impressive brightness levels to support its high-dynamic-range content.
At the lower end of the spectrum, we clocked the minimum brightness at 1.8 nits for point white.

The inclusion of a 90Hz refresh rate is now a baseline requirement for modern smartphones, and the A18 4G meets this standard. The device lacks an adaptive or automatic switching mechanism, offering instead two static options: a 60Hz standard mode and a 90Hz high-refresh mode. Given that 90Hz typically incurs a negligible power penalty over 60Hz, there is little reason not to keep the smoother setting active. While the A18 4G isn't a gaming powerhouse, you may find a few lightweight titles capable of exceeding 60fps to take advantage of the hardware, though this is the exception rather than the rule.
HDR support is absent here, as the device lacks hardware decoders for any major HDR formats. On a positive note, the phone carries the Widevine L1 DRM certification, ensuring that streaming services like Netflix can deliver content in full HD.
Battery life
Powering the Galaxy A18 4G is a 5,000 mAh Li-ion battery, a capacity that has become the default blueprint for Samsung's recent designs. With standard battery chemistry, our expectations were modest, though the efficiency of the Exynos 1610 chipset—a fresh iteration of a known architecture—added a variable to the equation.
The A18 4G delivered an Active Use Score slightly exceeding 13 hours. While these results aren't revolutionary, they are consistent with our expectations and slightly better than anticipated. It won't outlast competitors equipped with massive cells, such as the Honor 600 or the Xiaomi Poco M8 Pro, but it comfortably provides more than a full day of usage on a single charge.
Charging speed
Staying true to Samsung's entry-level formula, the Galaxy A18 4G supports 25W charging. While Samsung markets this under the "Samsung Fast Charging" (SFC) umbrella—a branding effort that has become increasingly convoluted over the years—the technical reality is simpler. Under the hood, this 25W implementation relies on standard USB Power Delivery (PD) and PPS. There are no proprietary PPS profiles to worry about, meaning a standard, non-e-marked 3A Type-C to Type-C cable (like the one included in the retail box) works perfectly.
Although 25W Samsung bricks are common, buyers should be wary of the numerous counterfeits circulating in the market, particularly those found in certain Russian regional packaging. To ensure safety and performance, stick to reputable vendors or any high-quality third-party adapter that supports dynamic PPS between 3.3V and 11V at a minimum of 2.25A (though 3A is the standard for most).
Using an official Samsung 25W charger and the provided cable, we put the device to the test. Samsung claims a 0% to 50% charge time of roughly 30 minutes, a figure our results mirrored. We recorded a climb to 29% in the first fifteen minutes and 48% by the half-hour mark. However, the journey to 100% took longer than anticipated, clocking in at nearly an hour and a half. Power meter data revealed a significant drop in charging speed after the 80% threshold, suggesting that Samsung has prioritized long-term battery health over raw top-up speed for the A18 4G.

The software includes several battery preservation tools, though they are relatively standard. Notably, a bypass charging option is tucked away within the Game Booster settings, and users have the option to disable Fast Charging entirely. The "Basic" protection mode maintains the battery by charging to 100% and pausing until it dips to 95%. For more control, "Maximum" protection allows users to set a custom ceiling at 80%, 85%, 90%, or 95%. There is also a "Sleep time protection" feature designed to hold the charge at 80% overnight and finish the top-off just before the user wakes up. It is worth noting that "Maximum" protection and "Sleep time protection" are mutually exclusive; the latter requires the basic 95% threshold.
Audio Performance: Volume and Fidelity
As expected for this price point, the Galaxy A18 4G utilizes a single speaker located at the bottom. If you are looking for a hybrid stereo configuration, you'll need to step up to the Galaxy A37.
Last year's Galaxy A17 (5G model) saw a slight dip in volume, landing it in our "GOOD" category. This year, the Galaxy A18 4G has been retuned to match the loudness of the Galaxy A16, earning it a "VERY GOOD" rating on our scale.
While the volume increase is a positive, the actual audible difference is minimal, and loudness isn't the primary concern here. The sound profile remains flat and uninspired, with distortion becoming evident at maximum volume. That said, this level of audio quality is typical for the budget segment.
Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
Samsung provides an equalizer with various presets and manual sliders that apply to both the internal speaker and connected headphones. Users also have access to Loudness normalization and "Adapt sound," a feature that tailors the audio profile based on the user's age. While Dolby Atmos and the UHQ upscaler are available, they are restricted to headphone use only.
Connectivity
As the name implies, the Galaxy A18 4G is strictly limited to 4G connectivity. While it lacks eSIM capabilities, it does support dual LTE connections via two physical nanoSIM slots. However, users should note that the second slot is a hybrid design; you must decide between utilizing a second cellular line or expanding your local storage with a microSD card.
For positioning, Samsung has equipped the device with a comprehensive suite including GPS, GLONASS, GALILEO, BDS, and QZSS. Wireless options consist of Bluetooth 5.3 (with LE support) and dual-band Wi-Fi ac, though the newer 6 GHz bands are absent. NFC is available, but its inclusion varies by region, so it is advisable to verify this with your retailer. Notably, the chassis omits a 3.5mm headphone jack, an FM radio, and an IR blaster.
Data transfers are handled via a USB Type-C port running on the USB 2.0 standard, capping theoretical speeds at 480 Mbps. While the device supports USB OTG/Host functionality, it lacks video output capabilities. Furthermore, wireless Samsung DeX is not officially supported on the A18 4G, despite some community-led attempts to enable it with inconsistent results.
Under the hood, the sensor array is quite robust. The device features a Sitronix STK61A10 light sensor, an Asahi AK09918C magnetometer and compass, and an STM LSM6DSVTR gyroscope and accelerometer pairing. Proximity detection is handled virtually via an "Ear Hover Proximity Sensor (ProToS)." This differs from the virtual approach used in the Galaxy S series, which typically retains a hardware sensor but restricts its access for third-party software. Finally, there is no onboard barometer.
Software and performance
Software Experience: One UI 9 and Android 17
Out of the box, the Galaxy A18 4G runs the latest software stack from Samsung, pairing One UI 9 with Android 17. The pace of evolution for both the Android ecosystem and Samsung's proprietary skin has been aggressive; for context, the previous Galaxy A17 debuted with One UI 7 and Android 15.
One of the most compelling selling points for the A18 4G is Samsung's commitment to six major OS upgrades. While this long-term support is an attractive prospect for consumers, it raises concerns regarding the hardware's longevity—specifically the 4GB of RAM. While the current user experience isn't exactly broken or unusable, there is a perceptible sluggishness to the interface. Ensuring the device remains fluid as future, more demanding versions of Android are deployed on just 4GB of memory will be a significant uphill battle for developers.
On a positive note, Samsung is increasingly integrating premium software utilities into its entry-level lineup rather than stripping them away. A standout addition is the "Warranty and care" menu. This centralized hub streamlines troubleshooting and support for the Galaxy A18 4G while aggregating data for all your Samsung ecosystem devices. Much of this content is intelligently curated from Samsung Members. More importantly, Samsung has avoided the common industry trend of burying support channels; although you'll likely start with a chatbot, reaching a human representative for remote technical assistance is surprisingly straightforward.
A dive into the Advanced Features settings reveals a surprisingly robust suite of options.
The "Connected devices" section is similarly impressive. While high-end tools like DeX are absent or hidden, the A18 4G still supports Multi control, "Continue on other devices," wireless casting, and Link to Windows. Additionally, users have access to Android Auto and the updated Driving report menu, making the software package feel surprisingly complete.
The most glaring omission, however, is the absence of the "Galaxy AI" suite found on S-series flagships. There is no visible integration of Perplexity or Bixby, and the AI-powered editing tools typically found in the Gallery app are missing. This is a logical trade-off; local AI models would likely overwhelm the 4GB of RAM, and cloud-based compute costs are likely too high for a budget device. Similarly, Samsung's "Now Brief" has been swapped out for the standard Google feed.
On the software front, the user experience remains largely consistent with Samsung's current design language. Those familiar with recent Galaxy devices will find the interface intuitive, though there are some welcome quality-of-life tweaks. For instance, users now have the option to increase the height of the volume and brightness sliders within the quick settings panel for easier adjustment.
Performance Analysis and Benchmarks
Moving away from the MediaTek Helio G99—which powered the 4G versions of the Galaxy A16 and A17—Samsung has pivoted back to its own silicon for the Galaxy A18 4G, introducing the Exynos 1610. While some critics have dismissed this chip as a simple 4G-only derivative of the Exynos 1330 or 1280, our investigation tells a different story. A deep dive into the kernel source code reveals that the Exynos 1610 (internally designated as S5E8365) features a fundamentally redesigned pipeline, proving it is far more than a mere "modem swap" or a rebranded legacy chip.
One notable improvement over the Exynos 1280 is the upgraded Image Signal Processor (ISP). While the 1280 was capped at 4K@30fps video recording, the 1610 is technically capable of 4K@60fps. It is important to note that the Galaxy A18 4G cannot even record in 4K@30fps; however, this appears to be an artificial software limitation imposed by Samsung for market segmentation rather than a hardware deficiency. Additionally, the Multimedia Format Codec (MFC) has been refreshed to provide broader hardware decoding support, specifically adding native VP9 decoding. Given that some Exynos 1280 devices eventually received 4K capabilities, it's possible the 1610 will do the same in a more premium A-series model. For the record, our attempts to bypass the A18 4G's 4K restrictions using Open Camera were unsuccessful.
When compared to the Exynos 1330, the differences are less about raw power and more about connectivity. Aside from the lack of 5G, the 1330 isn't significantly superior. Although the 1330 supports LPDDR5 RAM while the 1610 is limited to LPDDR4X, Samsung typically uses the slower LPDDR4X in budget handsets (like the A14 5G and A17 5G) to keep costs down. Interestingly, the GPU situation favors the 1610; while both use the Mali-G68, the Exynos 1330 utilizes only two cores, whereas the 1610 (and the 1280) appears to employ a four-core configuration.
In summary, the Exynos 1610 is a budget-oriented 4G SoC built on the 5nm (Samsung 5LPE) process. Its architecture consists of two Cortex-A78 cores clocked at 2.4GHz, six Cortex-A55 cores at 2.0GHz, and a Mali-G68 MP4 GPU. If a comparison is necessary, the Exynos 1280 is the more accurate benchmark for this chip's performance profile.
The memory configuration is somewhat concerning. While official specifications are scarce, the A18 4G likely utilizes LPDDR4X RAM and is limited to just 4GB. This is a meager amount for a device Samsung claims will be supported through six major OS upgrades—especially since the A16 4G and A17 4G offered higher RAM tiers. This appears to be a direct result of the ongoing semiconductor shortages persisting into 2026.
Storage options are equally puzzling. We encountered several mentions and retail listings for a 64GB version of the A18 4G. Upon contacting Samsung, the company confirmed that a 64GB model does exist for specific markets, though they declined to provide technical details regarding the flash memory class.
Despite the low capacity, it is unlikely that Samsung has reverted to eMMC 5.1, a standard now mostly reserved for ultra-budget tablets. Samsung has shifted its primary smartphone production to Universal Flash Storage (UFS). Attempting to run One UI 9.0 and Android 17 on eMMC would likely result in severe system lag, a bottleneck Samsung is unlikely to accept for its main lineup.
This suggests that the mysterious 64GB model must rely on UFS technology. A glance at Samsung Semiconductor's current catalog confirms that 64GB UFS chips are still in production, though they are limited to legacy, high-stability standards such as UFS 2.1 and UFS 2.2. Samsung's cutting-edge storage tiers—UFS 3.1, 4.0, and the imminent 5.0—typically begin at 128GB or 256GB. This is due to the technical constraints of block allocation and the performance degradation that occurs when formatting sophisticated V-NAND into smaller capacities. Consequently, these smaller chips aren't intended for the consumer smartphone market; they are designed for industrial automation, ADAS modules, automotive infotainment, and entry-level IoT frameworks where 128GB would be an unnecessary expense. Essentially, 64GB eUFS is reserved for smart home hubs, car dashboards, and budget electronics with minimal storage needs.
Drawing from Samsung Newsroom data, the existence of a 64GB Galaxy A18 4G is genuinely perplexing. While our test device features a 128GB/4GB configuration, a 256GB/4GB variant is also available. It is worth noting that both versions support expandable storage.
While we may be spending a significant amount of time analyzing a budget-tier processor, the Exynos 1610 remains a point of interest. Benchmark data shows the CPU performing exactly as anticipated: it slightly outperforms the MediaTek Helio G99 it succeeds and sits comfortably alongside the Dimensity 7100, Snapdragon 6 Gen 3, and the previously mentioned Exynos 1280 and 1330. That said, the Snapdragon and Dimensity chips maintain a slight advantage during heavy multi-core workloads.
AnTuTu scores mirror these findings, placing the Galaxy A18 4G in the same performance bracket as the Galaxy A16 5G, A17 5G, and A25—hardly a performance beast, but consistent for its class.

Thermal-throttling
The Exynos 1610 may lack raw power, but it excels in thermal management. Unlike the volatile heat profiles of modern flagship processors, this chipset generates very little heat and almost never suffers from thermal throttling.
The device's cooling system handles the minimal heat output with ease, ensuring the chassis never feels more than slightly warm to the touch.
Camera - photo and video quality
Imaging: A 50MP Primary and 13MP Front-Facing Setup
Samsung is playing it safe with the camera array on its budget-friendly A-series. The Galaxy A18 inherits a hardware configuration nearly identical to the A17 (both 4G and 5G variants), which itself was a carry-over from the A16. In terms of sheer quantity, the device is well-equipped, sporting a triple-lens rear assembly and a dedicated selfie shooter.
Of the three rear sensors, the 2MP macro lens offers limited practical utility for the average user. The ultrawide option, featuring a 5MP sensor and a 17mm equivalent focal length, isn't particularly expansive or detailed, but it remains a welcome addition over having no wide-angle capability at all.
The heavy lifting is handled by the 50MP primary sensor. With a 1/2.76" optical format, this sensor is often relegated to secondary roles in mid-to-high-end smartphones, but as a lead camera for a device in the A18's price bracket, it is a competent and well-specified choice.
The front-facing camera is similarly impressive for this tier. The 13MP sensor, utilizing a 1/3.1" optical format, holds its own not only against entry-level rivals but also against some more expensive models, though it relies on a fixed-focus lens.
- Wide (main): 50MP (1/2.76", 0.64µm-1.28µm); 26mm, f/1.8, OIS, PDAF; 1080p30 video recording.
- Ultrawide: 5MP (1/5.0", 1.12µm); 17mm, f/2.2, fixed focus; 1080p30.
- Macro: 2MP; 22mm, f/2.4, fixed focus.
- Front camera: 13MP (1/3.1", 1.12µm); 27mm, f/2.0, fixed focus; 1080p30.
Daylight Performance
Primary Sensor
Under the glare of bright sunlight, the A18's main camera delivers respectable 1x results. Images generally exhibit strong dynamic range, precise white balance, and vibrant colors, all while maintaining a fair level of detail. However, this performance dips when moving indoors; lower light levels quickly lead to a noticeable loss in both sharpness and color saturation.
Consequently, portrait photography is heavily dependent on the environment; the less light available, the more the quality suffers. Using the dedicated Portrait mode often results in a further decline in image fidelity, especially when lighting is suboptimal.
When lighting is optimal, the 50MP primary sensor delivers a noticeable boost in fine detail. These high-resolution shots are surprisingly crisp and feel like genuine captures rather than software-upscaled versions of binned images. However, this clarity comes with trade-offs: noise becomes more apparent and the dynamic range suffers. That said, if you have the right lighting and a detailed subject, the full-resolution mode is a viable tool.
Conversely, the 2x zoom performance is underwhelming. At a 1:1 crop, the detail appears patchy and coarse, falling significantly short of the quality found in the 50MP 1x shots. For the best results, users are better off capturing a full 50MP image and cropping in manually.
When pushing the main sensor to 2x zoom for headshots, the results mirror our previous findings: the level of detail is underwhelming. It is also worth noting that the dedicated Portrait mode is restricted to 1x zoom and is unavailable at the 2x setting.
Ultrawide camera
With a modest 5MP sensor, the ultrawide lens naturally struggles to capture high-resolution detail. However, within those hardware limitations, the images remain reasonably sharp. Under optimal lighting, the camera delivers pleasing color reproduction and balanced exposure. Performance dips indoors, where shadows become noticeably soft, though the results remain acceptable for casual use.
Macro Photography
While the A18's triple-lens array includes a dedicated macro sensor, the hardware—a 2MP fixed-focus wide-angle module—is hardly designed for high performance. The results are largely disappointing; while the subjects appear large in the frame, the actual level of detail is lacking, rendering the sensor more of a novelty than a useful tool.
Front-Facing Camera
The A18 holds its own surprisingly well when it comes to selfies. In bright lighting, the camera produces pleasing skin tones and respectable results, even if the fine detail can occasionally look a bit coarse or digitally processed. However, performance dips in less ideal conditions; indoor shots tend to lose sharpness, and the device struggles significantly when shooting in low-light environments.
Low-light photography performance
Primary sensor
When the lights go down, the main camera holds its own, provided there is at least a baseline level of ambient light. In extreme darkness—specifically in our second and fourth test scenarios—the results are notably soft, a trend that extends to the shadows even in better-lit environments. However, the device handles well-illuminated facades reasonably well, offering respectable dynamic range and generally accurate, though somewhat muted, color reproduction. It certainly doesn't compete with flagship-tier optics, but it is functional.
Switching to Night mode yields a noticeable improvement; it manages to lift the shadows, inject a bit more vibrancy into the colors, and enhance overall image sharpness.
While the 2x zoom struggled during the day, it becomes virtually useless once the sun goes down. Compounding the issue is the total absence of a dedicated Night mode for the 2x focal length, leaving you with no software safety net.

The ultrawide lens also lacks Night mode support, forcing you to rely on the standard output, which is plagued by noise and a lack of sharpness. Interestingly, the device manages to keep highlights under control and prevents shadows from becoming completely crushed, but this "dynamic range" feels hollow given the overall lack of fine detail.
Video quality
Across its entire camera array, the Galaxy A18 is capped at 1080p30 recording. The native camera application offers no 4K support and lacks a 60fps option, even when dropping down to 720p. While h.264 is the standard codec, users can opt for h.265 (HEVC) via the settings menu. Notably, there is no HDR video recording available.

When shooting in broad daylight, the primary sensor delivers respectable 1080p footage. We found the dynamic range to be well-balanced and the colors punchy without appearing artificial, maintaining a level of detail that is impressive for this resolution. However, performance dips significantly at 2x zoom, where the image becomes coarse and suffers from aggressive over-sharpening. While the ultrawide lens provides a broad perspective, the resulting footage is notably soft. Interestingly, the front-facing camera is a highlight, producing high-quality selfie videos despite being limited to 1080p.
As lighting conditions diminish, 1x video remains functional, though it is predictably underwhelming. We recommend avoiding the ultrawide lens and the 2x zoom entirely in low-light scenarios.
On paper, the A18 features system-wide stabilization, controlled via a global toggle in the settings menu. In practice, however, the main camera's handheld performance is disappointing; jitter is evident even when standing still and becomes quite pronounced while walking. Conversely, the ultrawide camera manages to produce significantly smoother, steadier footage.
Camera quality verdict
The Galaxy A18 is a rudimentary photography tool, which aligns with its entry-level specifications. The primary lens performs admirably at 1x in bright light and holds its own at night, provided you manually engage Night mode. This trend carries over to video—minus the Night mode option—where the 1080p cap is acceptable for this price bracket. The 2x zoom is consistently disappointing across all scenarios, and the ultrawide lens is only truly useful for daytime stills. On a positive note, both the photos and videos from the selfie camera are impressively strong for this class of device.
Final words, our verdict, pros and cons
Market Landscape and Alternatives
The global semiconductor crisis shows no signs of waning; if anything, the ripples are expanding to more product categories. We have already observed a €50 price hike for the S26 series at local retailers. Paradoxically, entry-level devices like the Galaxy A18 4G are hit hardest. While they utilize more affordable, lower-spec silicon, the price increases are far more punishing relative to their low MSRP.
Currently, the 4GB/128GB Galaxy A18 4G is retailing for roughly €280. This represents a disappointing shift in value compared to the previous Galaxy A17 4G, which debuted at €290 but offered double the storage and RAM (256GB/8GB). The situation becomes absurd with the 256GB A18 4G variant; where available, it commands a staggering €450 despite still being limited to 4GB of RAM. It is little wonder that most vendors have ceased stocking this specific configuration.
One potential lifeline for consumers—and a benefit for Samsung's vast existing inventory—is the availability of previous-generation hardware. For those seeking a basic "Galaxy" experience similar to the A18 4G, the Galaxy A17 is a smarter bet. It provides 5G connectivity and nearly identical specifications, with the added peace of mind that Samsung has committed to six major OS upgrades for the device.
That said, we strongly advise against purchasing a phone with only 4GB of RAM in 2026. For approximately €230, the base Galaxy A27 bumps that up to 6GB. However, since that price point is already nearing the A18 4G's asking price, it makes more sense to invest in the Galaxy A37 for about €270. While the base 128GB/6GB A37 lacks a microSD slot, it is vastly superior in every other metric: it features a brighter 120Hz display, 4K video recording, stereo speakers, and faster 45W charging.
Xiaomi's offerings mirror these market struggles. The Redmi Note 17 is the most direct rival to the A18 4G, offering 6GB of RAM in its base 128GB model, expandable storage, and a massive 7,700 mAh Si/C battery with 45W charging. However, unless battery life is your absolute priority, the Redmi Note 15 is the better choice. It boasts a superior HDR-certified screen, a more powerful chipset, 4K video capabilities, and stereo audio. Furthermore, an 8GB/256GB configuration is available for around €290, offering far better bang for your buck.
The Honor 600 stands out as a compelling alternative, currently priced around €220 for the 128GB model. While the lack of expandable storage may be a dealbreaker for some, the device compensates with 8GB of RAM and premium build quality, including IP68/69K water and dust resistance. It also features a high-brightness 120Hz HDR display, a capable Snapdragon 7 Gen 4 processor, stereo speakers, and Wi-Fi 7 (tri-band in select markets). While the EU model's 6,400 mAh battery is slightly smaller than the 7,000 mAh international version, it remains impressive. The camera system also comfortably outperforms the Galaxy A18 4G.
For those weighing their options, the Motorola Edge 70 Fusion presents a compelling alternative. While it similarly lacks expandable storage, its €280 price tag buys you a more generous 256GB of internal space and 8GB of RAM. It further distinguishes itself with a high-brightness display featuring a 144Hz refresh rate and HDR10+ support, paired with a capable chipset, quality stereo audio, and a large battery with fast-charging capabilities. In our estimation, it's a formidable value proposition.
Our verdict
The Samsung Galaxy A18 4G isn't fundamentally flawed. Viewed in a vacuum, it is a balanced budget device that hits almost every mark expected from this specific tier of the Galaxy family. It feels sturdy in the hand, benefits from IP64 dust and water resistance, and utilizes a pleasant 90Hz Super AMOLED panel. Battery endurance is reliable, and the primary sensor captures respectable images. While the new Exynos 1610 isn't a performance beast, it remains thermally efficient and offers a modest upgrade over the Helio G99 found in previous 4G iterations.
There are several aspects of the A18 4G that genuinely impress. In an era where microSD slots are vanishing, the inclusion of expandable storage is a win. Additionally, the speaker output is impressively loud, and the software experience remains a primary draw. One UI 9 is packed with features regardless of the hardware tier, and the commitment to six major OS upgrades is an industry-leading promise for a budget handset.
However, that long-term software promise exposes a critical weakness. Every known configuration of the Galaxy A18 4G is limited to 4GB of RAM. By 2026 standards, this is a significant bottleneck that causes noticeable lag even now. Expecting this meager memory to smoothly handle six future versions of Android is, at best, overly optimistic. Other compromises further dampen the experience: the return to Gorilla Glass 3 is a step backward, stereo speakers are still missing, and video recording is capped at a basic 1080p30. Furthermore, the ultrawide lens is mediocre, the macro sensor feels like a spec-sheet filler, and the 2x zoom offers little practical value.
Most of these omissions would be forgivable if the device were truly cheap. That is precisely where the Galaxy A18 4G falters.
Priced at approximately €280 for the 128GB/4GB model, the A18 4G enters a precarious market. We acknowledge that 2026 is an anomalous year for pricing, with chip shortages squeezing the budget sector. Even so, the competition is simply too fierce. Samsung's own legacy devices, such as the Galaxy A17 5G, are still available, and spending just a bit more—or sometimes less—unlocks devices with superior RAM, faster processors, more vibrant displays, stereo audio, rapid charging, and better camera systems.
To be clear, the Galaxy A18 4G is not a bad smartphone. It is a quintessential entry-level Samsung: predictable, reliable, and supported by a gold-standard update policy. It becomes an attractive option if bundled with a generous carrier contract, once retail prices drop, or for users who prioritize the Samsung ecosystem over raw performance.
At its current MSRP, however, it is a difficult recommendation. Samsung has built a perfectly logical phone but priced it illogically. While the hardware fulfills its basic purpose, the surrounding market makes it hard to endorse.
