If you are choosing between an old favorite and a modern mid-ranger, the difference is huge. The Samsung Galaxy A55 feels smooth, fast, and future-ready, while the Galaxy A8 (2018) feels tired today. From my real testing, the A8 now struggles with apps, heat, and battery life. The A55 runs cooler, lasts longer, and handles games with ease. Displays are worlds apart too. This Samsung Galaxy A8 (2018) vs Samsung Galaxy A55 comparison shows one thing clearly. Time matters. New chips, better cameras, and stronger batteries change daily use more than specs on paper. 

The Bangladesh price comparison data comes from MobileDokan, BDPriceInfo, and real resale listings on Bikroy, which many local buyers trust before purchasing. MobileDokan lists the Samsung Galaxy A55 official price in Bangladesh between BDT 38,000 and 42,000, based on storage and stock. BDPriceInfo confirms this range and explains that official units cost more due to VAT, sealed box assurance, and Samsung warranty support. Grey-market sellers on Bikroy list the Galaxy A55 between BDT 34,000 and 36,000, but these units often come without warranty and prices change often. 

The Samsung Galaxy A8 (2018) is officially discontinued. MobileDokan confirms this status. Bikroy listings show used prices between BDT 7,000 and 10,000, depending on condition and battery health. In this segment, buyers also look at the Samsung Galaxy A34, which offers longer software support and sits below the A55 in price, making it a safer choice for budget users in Bangladesh. 

Gaming on the Galaxy A8 (2018) feels hard today. The phone uses the Exynos 7885 chip with a Mali-G71 GPU. This was fine years ago. Now it feels weak. According to NanoReview, both the CPU and GPU are slow by today’s standards. Games like PUBG and COD Mobile lag often. The phone heats up fast. Long gaming sessions drain the battery quickly. 

The Galaxy A55 feels much better for gaming. Geekbench data shows its Exynos 1480 chip is far more powerful. MobileDokan also confirms it has a 120 Hz Super AMOLED display and better heat control. In real use, games run smooth and stable. The phone stays cooler. Heavy games like Genshin Impact are playable. The Galaxy A8 cannot run these games anymore. 

Using these two phones side by side feels like a big time jump. The Galaxy A55 feels modern and smooth, while the Galaxy A8 clearly shows its age in daily use. 

• Daily speed feels very different
  The Galaxy A55 feels fast and smooth in daily use. Apps open quickly and switching feels easy. The Galaxy A8 feels slow now. It pauses and stutters with modern apps.

• Gaming and heat control
  The A55 stays cooler during long gaming sessions. Frame drops are rare. The A8 heats up fast and slows down after a short time.

• Battery life in real use
  The A55 easily lasts a full day, even with gaming and video. The A8 struggles to last a full day now due to its small and aged battery.

• Display comfort
  The A55 screen scrolls smoothly and feels easy on the eyes. The A8 display looks fine but feels stiff and less smooth today.

• Camera reliability
  The A55 takes clearer photos in low light and daylight. The A8 camera works only in good light and misses detail.

• Network and future use
  The A55 supports 5G and newer networks. The A8 is limited to 4G and feels outdated for long-term use.

Bottom Line:  The Galaxy A55 is the clear upgrade for modern use. It is faster, cooler, and lasts much longer on a single charge. The Galaxy A8 (2018) can still handle basic tasks, but it feels outdated today. For long-term use in Bangladesh, the Galaxy A55 is the smarter and safer choice. 

According to Wikipedia, Samsung Bangladesh, and Smartprix, the Galaxy A8 (2018) comes with a single 16 MP rear camera (f/1.7) with PDAF and an LED flash. It supports HDR and records video at 1080p at 30 fps only. In good daylight, photos look clear, but in low light, detail drops and noise increases. On the front, it offers a dual selfie camera setup (16 MP + 8 MP, f/1.9), also limited to 1080p video, which was impressive in 2018 but feels dated today.

The Galaxy A55 is much more advanced. Samsung confirms a triple rear camera system with a 50 MP main sensor (f/1.8) with OIS, a 12 MP ultra-wide, and a 5 MP macro camera. It supports HDR and panorama and records 4K video at 30 fps with gyro-EIS. The 32 MP front camera (f/2.2) captures sharper selfies with better color and dynamic range. 

The display difference feels clear the moment you turn both phones on. The Galaxy A8 (2018) has a 5.6-inch Super AMOLED screen with Full HD+ resolution and a 60 Hz refresh rate. Colors still look rich, and text stays sharp because of the high pixel density. But scrolling feels slow today, and the smaller screen feels tight for videos or reading.

The Galaxy A55 takes a big step forward. It uses a larger 6.6-inch Super AMOLED display with Full HD+ resolution and a smooth 120 Hz refresh rate. Scrolling feels fast and easy on the eyes. Samsung also adds HDR10+ support, which helps videos look brighter and more detailed. Gorilla Glass Victus+ gives better protection too. Overall, the A55 display feels more modern, more comfortable, and much better for long daily use. 

If you want a phone that feels smooth, fast, and reliable for years, the Galaxy A55 is the easy choice. It handles gaming, cameras, battery life, and networks much better. The Galaxy A8 (2018) only makes sense if you need a very basic phone for calls and light use. For most users in Bangladesh today, the Galaxy A55 is the safer and smarter buy. 

Using the Galaxy A8 (2018) today feels like revisiting an old memory. It still works for calls, messages, and light use, but age shows in speed, battery, and cameras. The Galaxy A55 feels fresh and confident. Everything runs smoother, the screen is easier on the eyes, and the camera is more reliable in daily life. If you want a phone that will last and feel good to use in Bangladesh, the Galaxy A55 is the one I would recommend without hesitation.
