Oppo A57 Review: An Affordable Selfie-Centric Smartphone.
Introduction
Oppo has been gaining popularity for its innovative smartphones that cater to various user needs. The Oppo A57 is one such device that targets the mid-range market, offering an appealing blend of affordability and camera prowess. In this in-depth review, we will thoroughly examine the Oppo A57, focusing on its design, display, performance, camera capabilities, software experience, battery life, and overall value for money. By the end of this review, you will have a comprehensive understanding of whether the Oppo A57 is the right choice for your smartphone needs.
Design and Build Quality
The Oppo A57 comes with a sleek and slim design, making it comfortable to hold and use with one hand. Its build quality is decent, featuring a plastic body with a metallic finish that mimics the appearance of more premium smartphones. While the plastic construction may not feel as premium as metal or glass, it helps keep the device lightweight and less prone to fingerprints and smudges.
The front of the phone houses a 5.56-inch IPS LCD display with noticeable bezels on the top and bottom. The capacitive navigation buttons are placed below the display, and the power button and volume rocker are conveniently located on the right side. The fingerprint sensor is integrated into the physical home button, offering quick and secure unlocking of the device.
Display
The Oppo A57 sports a 5.56-inch IPS LCD panel with a resolution of 720 x 1280 pixels. While the display is not Full HD, it still manages to deliver reasonably sharp and vibrant visuals for most everyday tasks. Colors appear natural, and viewing angles are adequate, ensuring a satisfactory multimedia experience.
However, in comparison to other smartphones in its price range, the lack of a Full HD display might be disappointing for users who prioritize high-resolution content consumption and gaming. Nonetheless, for casual users who primarily use their smartphones for social media, browsing, and occasional video streaming, the display should suffice.
Performance
Under the hood, the Oppo A57 houses an octa-core MediaTek MT6765G Helio G35 (12 nm) processor, coupled with 4GB of RAM. While this configuration is not the most powerful, it offers a smooth and lag-free experience for day-to-day tasks like web browsing, social media, and light multitasking.
However, the Oppo A57 may struggle with resource-intensive applications and gaming. Users who engage in heavy gaming or run multiple apps simultaneously may experience occasional slowdowns and stutters. Nonetheless, for its price range, the device provides acceptable performance.
Software Experience
The Oppo A57 runs on ColorOS 3.0, Oppo’s custom Android skin. ColorOS aims to deliver a user-friendly experience with various customizations and features. The interface closely resembles iOS, which may appeal to users transitioning from iPhones or those who prefer a simplified and familiar UI.
ColorOS offers several gestures and shortcuts for easy navigation and access to features. Additionally, it comes with various pre-installed apps, some of which can be considered bloatware. However, users have the option to uninstall or disable unwanted apps to declutter the interface.
Camera:
One of the standout features of the Oppo A57 is its camera capabilities, particularly the front-facing selfie camera. The device boasts a 13MP rear camera with an f/2.2 aperture, which performs well in well-lit conditions, capturing detailed and adequately exposed shots. However, in low-light situations, the camera struggles, resulting in some noise and loss of detail.
The star of the show is the 8MP front-facing camera, specifically designed for selfie enthusiasts. The front camera delivers impressive results, capturing sharp and vibrant selfies with accurate skin tones. Oppo’s beautification features are a hit among users who enjoy retouching their selfies before sharing them on social media.
Battery Life
Powering the Oppo A57 is a non-removable 5000mAh battery. Considering the lower resolution display and power-efficient processor, the device manages to provide satisfactory battery life for moderate usage. For light to moderate users, the phone should last a full day on a single charge. However, heavy users may need to recharge the device before the day’s end.
Connectivity
The Oppo A57 offers standard connectivity options, including 4G LTE, Wi-Fi, Bluetooth, and GPS. Call quality is clear, and the device handles network reception well. The loudspeaker produces decent sound quality, though it may lack depth and loudness compared to more expensive smartphones.
Conclusion
In conclusion, the Oppo A57 is an affordable smartphone that caters to selfie enthusiasts and casual users. Its sleek design, selfie-centric camera, and user-friendly software make it an attractive choice in the mid-range segment. The display and overall performance are adequate for everyday tasks, but the absence of a Full HD display and some occasional lags in performance may not be suitable for power users or avid gamers.
If you prioritize taking high-quality selfies and desire a budget-friendly smartphone, the Oppo A57 is worth considering. However, if you demand a more powerful device with a Full HD display and smoother performance, there are other options available in the market that may better suit your needs. Ultimately, the Oppo A57 offers good value for money for users seeking an affordable and camera-focused smartphone experience.
