If you are choosing between the Samsung Galaxy A8 (2018) and the Samsung Galaxy S24, the answer is simple: the Galaxy S24 is superior in every real-world way that matters today. From my real testing experience, the A8 (2018) struggles with modern apps, gaming, and camera reliability, while the S24 delivers flagship-level speed, a bright AMOLED display, dependable cameras, and all-day battery efficiency. This Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 comparison highlights a massive generational leap in processor performance, RAM management, display smoothness, camera consistency, and long-term software support. 

The Samsung Galaxy A8 (2018) and the Samsung Galaxy S24 sit in two completely different price worlds in Bangladesh. The Galaxy A8 (2018) is no longer officially sold, so anything you find today comes from the used or refurbished market. Prices usually fall between BDT 28,000 and 35,000, depending on condition and storage. There is no official warranty, and battery health varies a lot. Buying it now feels like buying an old motorbike that still runs, but you never know how long it will last.

The Galaxy S24, on the other hand, is a current flagship and officially available. The official Bangladeshi price usually stays around BDT 72,000 to 75,000, while grey-market units often drop to BDT 59,000 to 65,000. Official units come with full Samsung warranty, while grey units rely on shop support only. This price gap exists because the S24 offers modern hardware, long software support, and full 5G readiness for Bangladesh networks. 

When you compare value, the difference becomes very clear. The Galaxy A8 (2018) may look cheaper, but it has no future updates and almost no resale value. The Galaxy S24 costs more upfront, but it stays relevant for years and holds value much better. If you are considering alternatives near the A8 (2018) price, newer phones like Samsung Galaxy A15 or Samsung Galaxy A05s make more sense today. If the Galaxy S24 feels too expensive, a similar and slightly cheaper option worth checking is the Samsung Galaxy S23 FE, which still offers strong performance and official support in Bangladesh.

When comparing Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 for gaming, the difference feels massive from the first match. The Galaxy A8 (2018) uses the Exynos 7885 processor with an older Mali-G71 GPU. Modern games like PUBG Mobile, COD Mobile, and Asphalt 9 run only on low settings, usually staying around 25 to 30 FPS. After 15 to 20 minutes, heat builds up and frame drops become common. Long gaming sessions feel slow and uncomfortable.

The Galaxy S24 is built for modern mobile gaming. Its flagship processor handles heavy titles smoothly at high or ultra settings, with frame rates staying close to 60 FPS. Thermal management is far better, so performance stays stable during longer sessions. Touch response feels quicker, and online gameplay remains reliable.

In short, the Galaxy A8 (2018) is fine for light gaming only. The Galaxy S24 delivers smooth, stable gaming that matches today’s expectations. 

When you compare Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 in daily use, the gap feels far bigger than the spec sheet suggests. These are differences you actually notice every day.

• Overall speed and smoothness: The Galaxy A8 (2018) feels slow with modern apps, while the S24 stays fast and fluid, even with heavy multitasking.

• Software support: The A8 (2018) has stopped receiving major updates, but the S24 comes with long-term Android and security updates directly from Samsung.

• Camera consistency: Photos from the A8 (2018) struggle in low light, while the S24 delivers clearer images, better night shots, and more reliable video stabilization.

• Display experience: The A8 screen still looks good, but the S24 feels smoother and easier on the eyes during scrolling and gaming.

• Battery confidence: Battery health on the A8 (2018) depends on past usage, while the S24 delivers predictable, all-day performance.

• Network readiness: The A8 (2018) is limited to older networks, but the S24 is fully ready for modern 5G use in Bangladesh.

In real life, the A8 (2018) feels dated. The Galaxy S24 feels future-proof. 

When comparing Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 for network use in Bangladesh, the difference shows up clearly in daily connectivity. The Galaxy A8 (2018) supports 2G and 3G on all local networks and 4G LTE on Grameenphone, Robi, Banglalink, and Teletalk. Voice calls and basic mobile data work reliably, but internet speeds feel limited today. In crowded areas like markets or buses, signal drops and slow data are more noticeable. There is no 5G support, and Wi-Fi performance is limited to older standards, which affects streaming and downloads.

The Galaxy S24 is built for modern Bangladeshi networks. It fully supports 2G, 3G, 4G LTE, and 5G on Grameenphone, Robi, Banglalink, and Teletalk where coverage is available. Call quality is clearer, data speeds are much faster, and network switching is smoother while moving. Newer Wi-Fi and Bluetooth standards also improve hotspot use, wireless audio, and file sharing.

In real use, the A8 (2018) still connects. The Galaxy S24 connects faster, stays stable, and is ready for Bangladesh’s network future. 

In the Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 camera comparison, the difference reflects six years of camera evolution. The Galaxy A8 (2018) uses a single 16 MP rear camera with an f/1.7 aperture. In good daylight, photos look acceptable with natural colors, but fine details are limited. Low-light images show visible noise, soft focus, and weaker dynamic range. Video recording is capped with basic stabilization, so handheld clips often look shaky.

The Galaxy S24 delivers a much more advanced experience. Its triple-camera system includes a 50 MP main sensor, supported by ultra-wide and telephoto lenses. Daylight photos are sharp with strong dynamic range, while night shots retain detail with controlled noise. Portraits show cleaner edge detection, and video benefits from advanced stabilization. Selfies are also clearer and more reliable indoors.

In daily use, the A8 (2018) feels outdated. The Galaxy S24 feels confident in every lighting condition.  

When comparing Samsung Galaxy A8 (2018) vs Samsung Galaxy S24 displays, the improvement is easy to see and feel. The Galaxy A8 (2018) features a 5.6-inch Super AMOLED display with Full HD+ resolution and a 60 Hz refresh rate. Colors look vibrant, blacks are deep, and outdoor visibility is decent for its time. However, brightness levels are limited, and scrolling feels dated by today’s standards.

The Galaxy S24 uses a 6.2-inch Dynamic LTPO AMOLED 2X display with Full HD+ resolution and a 1–120 Hz adaptive refresh rate. It supports HDR10+, delivers much higher peak brightness, and feels extremely smooth while scrolling or gaming. Text looks sharper, motion feels fluid, and outdoor visibility is excellent even under strong sunlight.

In daily use, the A8 (2018) display still looks pleasant. The S24 display feels modern, smoother, and far easier on the eyes. 

If you need a phone only for basic calls, light apps, and occasional use, the Galaxy A8 (2018) can still work, but only if you find it very cheap and in good condition. It is no longer a long-term option. The Galaxy S24 is the better choice for most people today. It offers faster performance, better cameras, longer software support, and full 5G readiness in Bangladesh. If you want a phone that will stay reliable for years, the Galaxy S24 is clearly the smarter buy. 

The Samsung Galaxy A8 (2018) still feels premium in hand, but it belongs to a past era. It handles basic tasks, yet struggles with modern apps, cameras, and networks. The Galaxy S24 is the clear winner, offering smoother performance, a far better camera, and long-term software support. If you want a phone that will last for years in Bangladesh, the Galaxy S24 is the smarter and safer choice.
