Samsung Galaxy A18 4G Review: Design, Display, Performance, Camera and Battery

Samsung continues to expand its affordable Galaxy A lineup with the new Galaxy A18 4G, a budget smartphone designed for users who want the familiar Samsung experience without moving into the company's more expensive models.

The Galaxy A18 4G focuses on the essentials, including a 90Hz Super AMOLED display, a 5,000mAh battery, expandable storage, a 50MP main camera, and Samsung's long-term software support. It also introduces the new Exynos 1610 chipset and improves dust and water resistance with an IP64 rating.

However, the phone also makes several compromises, including only 4GB of RAM, a basic 1080p video recording limit, a single speaker, and relatively slow charging compared with some competing budget smartphones.

Design and Build Quality

The Galaxy A18 4G follows the familiar design language used across Samsung's affordable A-series smartphones. It features a plastic rear panel and frame, with a glass front protected by Gorilla Glass 3.

The phone weighs 196 grams and measures 7.7mm thick. Although plastic construction is not particularly premium, the handset feels solid and does not give the impression of being cheaply assembled.

Samsung has also upgraded the protection rating to IP64, compared with the IP54 rating of the previous Galaxy A17 4G. This provides improved protection against dust and resistance to water splashes, although it should not be treated as a fully waterproof phone.

The design includes a vertically arranged triple-camera module, a waterdrop-style notch on the front, and a side-mounted fingerprint reader integrated into the power button.

Samsung offers the Galaxy A18 4G in understated colors such as Black, Gray and Light Blue, although the exact color names can vary by market.

One notable compromise is the front glass. The previous Galaxy A17 4G used Gorilla Glass Victus+, while the A18 4G switches to the older Gorilla Glass 3. This represents a step backward in terms of advertised drop and scratch resistance.

6.7-Inch 90Hz Super AMOLED Display

The Galaxy A18 4G features a 6.7-inch Super AMOLED display with a 1080 × 2340 resolution and a 90Hz refresh rate.

The panel offers approximately 385 pixels per inch and provides the typical AMOLED benefits of strong contrast, deep blacks and vibrant colors.

Samsung's display technology remains one of the more attractive features of the phone. Laboratory testing found brightness approaching 800 nits in bright conditions, while a smaller test window reached roughly 1,100 nits.

The display supports 90Hz, although users have to manually choose between 60Hz and 90Hz modes rather than getting sophisticated automatic refresh-rate switching.

There is no HDR support, but the phone does have Widevine L1 certification, allowing compatible streaming services such as Netflix to provide Full HD playback.

Performance and Exynos 1610

One of the biggest changes this generation is Samsung's decision to use its own Exynos 1610 chipset.

The processor uses a combination of two Cortex-A78 cores clocked at 2.4GHz and six Cortex-A55 cores running at 2.0GHz. Graphics processing is handled by a Mali-G68 GPU.

In everyday use, the chipset provides enough performance for common activities such as messaging, web browsing, social media and video streaming. It is not designed as a gaming-focused processor, however.

Benchmark results place the Exynos 1610 broadly around the performance level of several older midrange and upper-budget chipsets. It represents a modest improvement over the Helio G99 used in some previous Samsung 4G models.

The phone also performs consistently under sustained workloads and does not appear to suffer from excessive heat.

4GB RAM Could Become a Problem

The biggest concern with the Galaxy A18 4G is not necessarily its chipset but its memory configuration.

All known variants come with only 4GB of RAM, while storage options range from 64GB to 256GB.

Samsung deserves credit for retaining microSD support, but 4GB of RAM can already make the phone feel slower when several applications are open.

This becomes more important because Samsung promises up to six major Android OS updates. Long-term software support is excellent on paper, but maintaining smooth performance across several future Android versions with only 4GB of RAM could become challenging.

Battery Life and 25W Charging

The Galaxy A18 4G is equipped with a 5,000mAh battery, a capacity that has become standard across many Samsung smartphones.

Battery testing produced an Active Use Score of slightly more than 13 hours. In practical terms, most users should be able to comfortably get through a full day, with moderate users potentially getting longer.

Charging is handled through Samsung's 25W wired charging system.

In testing, the phone reached approximately 29% after 15 minutes and around 48% after 30 minutes. Samsung's claim of reaching 50% in roughly half an hour is therefore close to the measured result.

A complete charge takes considerably longer, approaching around 90 minutes, with charging slowing noticeably after the battery reaches approximately 80%.

Camera Setup

Samsung equips the Galaxy A18 4G with a triple-camera system on the rear.

The primary camera uses a 50MP sensor with optical image stabilization (OIS). It is accompanied by a 5MP ultrawide camera and a 2MP macro camera.

50MP Main Camera

The main camera is the strongest part of the rear camera setup.

In good lighting, it can capture reasonably detailed photographs with Samsung's familiar processing style. OIS also helps with handheld photography and low-light shooting.

Night photography is acceptable for the class, although users should not expect flagship-level dynamic range or detail.

5MP Ultrawide Camera

The 5MP ultrawide camera is useful when a wider field of view is needed, but its low resolution limits the amount of fine detail captured.

It is more suitable for casual landscapes, buildings and group photographs than detailed photography.

2MP Macro Camera

The 2MP macro camera is largely a specification-sheet addition. Its practical usefulness is limited, especially compared with the capabilities of the main camera.

13MP Selfie Camera

For selfies, Samsung uses a 13MP front-facing camera.

Image quality is generally suitable for social media, video calls and everyday photography, particularly under good lighting.

Video Recording

The Galaxy A18 4G supports video recording at up to 1080p at 30fps from its cameras.

There is no 4K video recording option, despite the Exynos 1610 chipset theoretically supporting more advanced video capabilities.

The main camera's stabilization is also relatively basic, so users looking for advanced video features will find the phone limited.

Connectivity

The Galaxy A18 4G supports 4G LTE and two physical nano-SIM cards, although the second SIM slot shares space with the microSD card.

Other connectivity features include:

• Wi-Fi 5
• Bluetooth 5.3
• GPS
• Galileo
• GLONASS
• BDS
• QZSS
• NFC on selected variants
• USB Type-C
• USB OTG

The USB connection is limited to USB 2.0 speeds. There is also no 3.5mm headphone jack, FM radio or IR blaster.

The phone does not support eSIM functionality.

Software and Updates

The Galaxy A18 4G launches with Android 17 and One UI 9.

Samsung's software remains one of the phone's strongest selling points. One UI provides a wide selection of customization and system features, even though the A18 sits near the entry level of Samsung's smartphone range.

More importantly, Samsung promises up to six major OS upgrades, giving the device unusually long software support for its class.

The main question is whether 4GB of RAM will remain sufficient as future Android versions and applications become more demanding.

Final Verdict

The Samsung Galaxy A18 4G is a straightforward budget smartphone that delivers the familiar Samsung experience without trying to reinvent the entry-level segment.

Its 90Hz Super AMOLED display, dependable battery life, expandable storage, IP64 protection, capable 50MP main camera and long software-support commitment are its biggest attractions.

The new Exynos 1610 provides respectable performance for everyday tasks and is a modest step forward from the older Helio G99 platform used in previous 4G Galaxy A models.

However, the 4GB RAM configuration is the phone's biggest concern, particularly given Samsung's promise of six major Android upgrades. The lack of stereo speakers, limited video recording, basic secondary cameras and relatively slow charging also make the hardware less impressive than some competing devices.

At launch, the Galaxy A18 4G was reported at around €280 for the 128GB/4GB model, while the 256GB version was considerably more expensive. That pricing makes the phone's overall value heavily dependent on local discounts and promotions.

For buyers specifically looking for Samsung's software experience, long-term updates, AMOLED display and expandable storage, the Galaxy A18 4G covers the basics well. Its appeal becomes more complicated when compared with other phones offering more RAM, faster charging or stronger hardware at similar prices.
