Samsung’s Galaxy A18 4G makes a promise that most phones at its price do not, which is six major Android upgrades, and the first full lab review shows how much weight that promise places on modest hardware. GSMArena’s testing found a phone with a good screen, long battery life and a cool-running new chip, but every version ships with only 4GB of RAM, and that is already where the phone feels slowest today.
That mismatch is the most useful lens for judging the A18 4G. Samsung is selling a phone built to last into the early 2030s on software, while the memory inside it is the component least likely to keep up, and the European launch price leaves little room to overlook that.
What the Galaxy A18 4G Gets Right
The Galaxy A18 4G’s clearest upgrade over the Galaxy A17 is durability, since its rating rises from IP54 to IP64, while its 6.7-inch 90Hz AMOLED screen and 5,000mAh battery carry over largely unchanged and still perform well. The other notable change is the processor, because Samsung has replaced the previous MediaTek chip with its new Exynos 1610, which GSMArena found never thermal-throttled during testing and never got more than lukewarm.

In GSMArena’s lab tests the screen reached about 800 nits on automatic brightness and roughly 1,100 nits at peak, which is bright enough for outdoor use at this price. The battery earned an Active Use Score of more than 13 hours, while the 25W charger filled about 48% in 30 minutes, which is adequate rather than quick. The single bottom speaker was rated very good for loudness, and One UI 9 brings Gemini and Circle to Search, although Samsung keeps the wider Galaxy AI suite, including generative editing and live translation, for its more expensive models.
Where the Galaxy A18 4G Falls Short
The weaknesses cluster around memory and cameras. With 4GB of RAM across every configuration, GSMArena found the phone sluggish in everyday use despite the new chip, and that limitation matters more on a phone promised six years of software, since future Android versions may put more pressure on its limited memory.
The cameras are the same as on the Galaxy A17. The 50MP main sensor takes decent photos in bright daylight with good dynamic range and accurate colour, but indoor shots lose sharpness and saturation, and the 2x zoom produces coarse, patchy detail that is worse than simply cropping a 50MP image. The 5MP ultrawide and 2MP macro add little, and video tops out at 1080p at 30 frames per second with visibly shaky stabilisation.
The Price Is the Real Problem
At €280 for the 128GB model the Galaxy A18 4G competes with phones that offer more for similar money, and GSMArena’s own list of alternatives makes the point. Samsung’s Galaxy A37 costs about €270 with 6GB of RAM, a 120Hz display, a better camera, stereo speakers and 45W charging, while the Redmi Note 15 offers 8GB and 256GB for around €290 along with 4K video, and the Honor 600 brings IP68 and 80W charging for about €220.
The 256GB version is harder still to justify at €450, since it keeps the same 4GB of RAM. The Galaxy A18 4G makes sense for buyers who want Samsung’s software and long update support in the simplest possible package, and particularly for those who can get it subsidised by a carrier or wait for the first discounts. For everyone else, Samsung’s own lineup offers better value, as Memeburn’s guide to the best Samsung phones shows.

FAQsIs the Galaxy A18 4G worth buying?
The Galaxy A18 4G is a solid budget phone with a good AMOLED screen, IP64 protection and six years of updates, but at €280 it costs more than rivals such as the Galaxy A37 and Redmi Note 15, so it is best bought on discount.
How much RAM does the Galaxy A18 4G have?
Every Galaxy A18 4G model has 4GB of RAM, with 128GB or 256GB of expandable storage and a 64GB version in some markets.
How long will the Galaxy A18 4G get updates?
Samsung promises up to six major Android OS updates for the Galaxy A18 4G, which ships with Android 17 and One UI 9.
Does the Galaxy A18 4G have Galaxy AI?
The Galaxy A18 4G includes Gemini and Circle to Search, but not the full Galaxy AI suite, as features such as generative photo editing and live translation are reserved for Samsung’s higher-end phones.
