The OnePlus Nord 3 and Samsung Galaxy A55 target mid range buyers but focus on different priorities. According to NanoReview’s direct comparison, the Nord 3 delivers higher overall performance thanks to the Dimensity 9000 chipset, making it better for gaming and heavy multitasking. The Galaxy A55 counters with stronger battery efficiency, IP67 water resistance, expandable storage, and longer software update support. Display quality is excellent on both, while camera results are more consistent on the A55. For performance focused users, Nord 3 leads. For long term daily reliability, A55 is the safer choice. 

According to MobileDokan, the OnePlus Nord 3 5G is listed in Bangladesh mainly through the unofficial market, as there is no confirmed official launch price. MobileDokan shows the 8GB RAM and 128GB storage variant priced at around ৳43,499. The listing confirms that availability is mostly dependent on the grey market.

For the Samsung Galaxy A55 5G, MobileDokan lists an official Bangladesh price of ৳75,499 for the 8GB RAM and 128GB storage variant. This price includes Samsung Bangladesh official warranty and authorized after-sales service. As an alternative with official warranty, the Samsung Galaxy A54 is also officially available in Bangladesh. 

Before writing this, I checked verified benchmark and gaming data from NanoReview, which compares both phones using the same testing methods and tools. All performance facts below come directly from that source.

When it comes to gaming, the OnePlus Nord 3 feels like the friend who never gets tired. NanoReview gives it a gaming score of 53, while the Samsung Galaxy A55 scores 36, showing a clear gap. In simple terms, the Nord 3 runs heavy games more smoothly. Its total performance score is 1,098,744, much higher than the A55’s 720,015, and that extra power shows up during real gameplay.

From my experience with similar hardware, this means fewer frame drops during long PUBG or COD Mobile sessions. The Galaxy A55 can still handle games, but it feels more cautious, like driving with the handbrake slightly on. The Nord 3 feels freer and faster, especially in demanding titles. 

These two phones may sit in the same mid-range bracket, but they feel very different in real life. The OnePlus Nord 3 focuses on speed and fast charging, while the Samsung Galaxy A55 prioritizes durability, efficiency, and long-term support.

• Display experience: The OnePlus Nord 3 uses a larger 6.74-inch AMOLED display with higher resolution and sharper pixel density, which feels more immersive for gaming and videos. The Samsung Galaxy A55 has a 6.6-inch Super AMOLED screen with stronger glass protection and better durability.

• Performance feel: The Nord 3 runs on the MediaTek Dimensity 9000 chipset, delivering much higher CPU and GPU performance. The Galaxy A55 uses the Exynos 1480, which feels smoother for daily tasks but slower under heavy load.

• Gaming behavior: The Nord 3 maintains higher frame rates and smoother gameplay in demanding titles. The A55 focuses more on stability than raw power.

• Battery and charging: Both phones have 5000 mAh batteries, but the Nord 3 charges much faster. The A55 charges slower but offers better long-term efficiency.

• Build and protection: The Galaxy A55 includes IP67 water and dust resistance, while the Nord 3 does not offer official water protection.

• Software support: The Galaxy A55 ships with newer Android and longer update support compared to the Nord 3.

Bottom line: If you want faster performance, smoother gaming, and very quick charging, the OnePlus Nord 3 is the better choice. If durability, water resistance, longer software support, and stable daily use matter more, the Samsung Galaxy A55 makes more sense for long-term ownership.

According to NanoReview’s verified comparison data, the OnePlus Nord 3 features a 6.74-inch AMOLED display with a 2772 × 1240 resolution and around 451 pixels per inch, resulting in sharper text and more detailed visuals. The larger screen also offers a more immersive experience when watching videos or gaming.

The Samsung Galaxy A55 comes with a 6.6-inch Super AMOLED display at 2400 × 1080 resolution and roughly 390 pixels per inch. While it is slightly less sharp, NanoReview notes that Samsung’s Super AMOLED panel provides strong color contrast and better outdoor readability. The A55 also benefits from tougher glass protection, which adds durability for daily use. Both displays support a 120 Hz refresh rate, ensuring smooth scrolling and animations. 

Choose the OnePlus Nord 3 if you care about faster performance, smoother gaming, and very fast charging for daily use. It feels more responsive and better suited for heavy users.
