OPPO A57 4G Price in Bangladesh
The official price of the OPPO A57 4G is 16,990 BDT in Bangladesh. This is the price set by OPPO Bangladesh and their authorized retailers across the country. You may also find this phone sold at unofficial or open-market shops, sometimes at a slightly lower price. However, buying from unofficial sources means you may not get a valid warranty, and after-sales service can become a problem if anything goes wrong. It is always safer to buy from an authorized OPPO dealer or trusted retail store. The OPPO A57 4G comes in multiple storage variants — 3GB RAM + 64GB, 4GB RAM + 64GB, and 4GB RAM + 128GB — so prices may vary slightly depending on which variant you choose. The phone is currently available in the market, so finding stock should not be difficult.
Key Specifications
The OPPO A57 4G runs on a MediaTek Helio G35 chipset built on a 12nm process, paired with either 3GB or 4GB of RAM along with OPPO’s Extended RAM feature that adds up to 4GB of virtual RAM. Storage options go up to 128GB and can be expanded via a microSDXC card up to 1TB. The phone supports Dual SIM with 2G, 3G, and 4G network bands. It runs Android 12 with ColorOS 12.1 out of the box and is upgradable all the way to Android 14 with ColorOS 14, which is a good sign for long-term software support. Connectivity includes USB-C, a 3.5mm headphone jack, and stereo speakers. It also has an IP5X + IPX4 rating for basic dust and splash resistance.
Display and Design
The OPPO A57 4G features a 6.56-inch IPS LCD screen with an HD+ resolution of 720×1612 pixels and a standard 60Hz refresh rate. The display includes OPPO’s AI Eye Comfort mode, which adjusts screen lighting to reduce eye strain during long use — a practical feature for students or people who use their phone for extended reading or streaming. The screen size is generous for the price range, making it comfortable for watching videos or browsing. Design-wise, the phone is available in two color options: Glowing Black and Glowing Green, both with a shimmery finish that looks attractive without feeling cheap. The side-mounted fingerprint sensor is conveniently placed and works reliably for quick unlocking.
Camera
On the back, the OPPO A57 4G has a 13MP main camera with an f/2.2 aperture and a 2MP depth sensor with an f/2.4 aperture for portrait shots. The dual rear camera setup can record video at 1080p at 30fps. For selfies, there is an 8MP front camera with an f/2.0 aperture, also capable of 1080p video recording at 30fps. In good lighting conditions, photos come out clean and detailed enough for social media use. Low-light performance is average, which is expected at this price point. The portrait mode works reasonably well for everyday photos. Overall, the camera is good enough for casual photography but may not satisfy users looking for high-quality shots.
Performance and Software
The MediaTek Helio G35 processor handles daily tasks like social media, messaging, video calls, and light gaming without major issues. The Extended RAM feature, which borrows up to 4GB from internal storage, helps with smoother multitasking when multiple apps are open. ColorOS 12.1, based on Android 12, is clean and offers useful customization options. The fact that OPPO has committed software updates up to Android 14 and ColorOS 14 means buyers get better long-term value from this device, which is not always guaranteed in budget phones.
Battery and Charging
The phone is equipped with a large 5000mAh battery that easily lasts a full day of regular use for most people. What makes it stand out in this segment is the 33W SUPERVOOC fast charging, which can charge the battery to 50% in just 30 minutes. This is a genuinely useful feature for users who are always on the move. The battery is non-removable, which is standard for modern smartphones.
Should You Buy the OPPO A57 4G?
The OPPO A57 4G is a solid choice for first-time smartphone buyers, students, and users who need a reliable daily driver without spending a lot. The big battery and fast charging are the strongest selling points at this price. The guaranteed software upgrade path to Android 14 adds further value. However, if you are a heavy gamer or care deeply about camera quality, you may want to look at a slightly higher budget option. Within the OPPO lineup, you could also consider the OPPO A77s or the OPPO A96 if your budget allows for a step up.
