        Last updated: 19 Oct 2026 from 78 live offers

        The Samsung Galaxy A18 4G is the newest entry point into Samsung's current A-series, pairing a 6.7-inch Super AMOLED display with a 5000mAh battery in a familiar budget design. It connects over 4G only, at a time when most rivals in this price bracket now include 5G as standard.

        Galaxy A18 4G: Display

        The 6.7-inch Super AMOLED panel runs at 90Hz with a full HD+ resolution of 1080 x 2340 pixels, sharper scrolling than the 60Hz screens common at this price. Panel size and resolution match the outgoing Galaxy A17 4G exactly.

        The protection glass is a step down though: Gorilla Glass 3 replaces the Gorilla Glass Victus+ used on the A17 4G, which should leave the screen more prone to scuffing without a case.

        Galaxy A18 4G: Camera

        The 50MP main camera keeps its f/1.8 aperture and optical image stabilisation, unusual at this price and likely to help in low light. A 5MP ultrawide, 2MP macro and 13MP selfie camera complete the setup.

        Video is capped at 1080p and 30fps on both cameras, with no 4K option, so keen social video creators should look further up Samsung's range.

        Galaxy A18 4G: Battery

        The 5000mAh cell should comfortably cover a full day of typical use, and Samsung rates the bundled 25W charger to reach 50 percent in 30 minutes.

        That charging speed is modest next to rivals now shipping 33W or faster, and there is no wireless charging here, so topping up always means reaching for a cable.

        Galaxy A18 4G: Size, Weight and Build

        At 164.4 x 77.9 x 7.7mm the Galaxy A18 4G stays easy to use one-handed, and Samsung has added an IP64 rating for dust and splash resistance, still missing from many budget rivals. It comes in Black, Grey and Light Blue.

        It is 6g heavier than the outgoing A17 4G at 196g, and like that model it drops the 3.5mm headphone jack, so wired headphones need a USB-C adapter.

        Galaxy A18 4G: Performance

        Samsung has switched to its own Exynos 1610 chipset with a Mali-G68 GPU, running Android 17 with One UI 9. It commits to six major OS upgrades from launch, matching the A17 4G and beating most budget Android rivals on long-term software support.

        Every storage tier ships with just 4GB of RAM, a step down from the A17 4G's 6GB and 8GB options at the same capacities, so multitasking headroom is tighter than on its predecessor.

        Galaxy A18 4G: Who Should Buy

        The Galaxy A18 4G suits buyers who want a large AMOLED screen and years of Samsung software support on a tight budget, without needing 5G or heavy multitasking power. Anyone who wants either should look elsewhere in Samsung's current A-series range, or consider the A17 4G's higher-RAM options while stock lasts. Buyers comparing storage tiers and current pricing will find the latest offers in the table above.
