For buyers in Bangladesh deciding between the Samsung Galaxy A55 vs OnePlus 12R, the OnePlus 12R delivers noticeably better overall performance, gaming ability and battery life, while the Galaxy A55 leans more toward a balanced mid-range experience with IP67 water resistance. From real test benchmarks, the Snapdragon 8 Gen 2 in the 12R easily outpaces the Exynos 1480 in everyday tasks, heavy apps and sustained gaming, and also gives faster charging and longer battery endurance, making it the better choice if power, display and longevity matter most. 

In the Bangladeshi market, the Samsung Galaxy A55 shows one of the largest price gaps between official and grey-market units. The official Samsung Galaxy A55 price in Bangladesh is ৳64,999 for the 8GB 128GB variant, which includes brand warranty, reliable after-sales service, and easier access to EMI options. However, unofficial pricing is far more aggressive, with the 8GB 128GB version selling around ৳34,000, the 8GB 256GB variant near ৳44,000, and the 12GB 256GB model around ৳45,000, depending on stock availability and seller reliability.

In contrast, the OnePlus 12R is available only through the unofficial market, where the 8GB 256GB variant typically costs around ৳55,000, while the higher 16GB 256GB version goes up to about ৳60,000. Within this broader price range, buyers also consider alternatives such as the Xiaomi Redmi Note 13 Pro or realme 12 Pro Plus, but neither matches the OnePlus 12R’s flagship-level performance.

Overall, the Galaxy A55 makes the most sense as a grey-market purchase for value-focused buyers, while the OnePlus 12R justifies its higher unofficial price with significantly stronger hardware and better long-term performance headroom.
