**Unboxing and First Look: Oppo A57**
The Oppo A57 is a smartphone that has been making waves in the market with its impressive camera capabilities. In this unboxing and first look, we'll take a closer look at the device's design, features, and performance.
Upon taking out the phone from its packaging, we can see that it comes with a sleek and premium design. The device feels solid in our hands, indicating a high-quality build material. The back of the phone has a matte finish, while the top part of the phone is made of glass. The phone's dimensions are quite compact, making it easy to carry around.
The Oppo A57 boasts an impressive array of features that make it stand out from its competitors. The front camera, which is embedded in the home button, is one of the standout features of this device. The phone comes with a 13-megapixel rear-facing camera and a 16-megapixel front-facing camera. This makes it an excellent option for those who want to capture high-quality selfies and images.
The Oppo A57 also features a large 5.2-inch screen, which is perfect for watching videos or browsing the web. The screen resolution is 720p, making it a good choice for casual users. One of the notable features of this device is its fast charging capabilities. The phone comes with a 2900mAh battery, which can last up to two days on a single charge.
Another feature that sets this phone apart from its competitors is its fingerprint scanner. The phone's fingerprint sensor is embedded in the home button and works quickly and accurately. This makes it easy to unlock the device or make payments using mobile wallets like Paytm.
**Design and Build Quality**
The design of the Oppo A57 is one of its standout features. The phone has a sleek and premium look, making it suitable for those who want a high-end smartphone without breaking the bank. The build quality of the device is also impressive, with a solid feel that suggests a high-quality build material.
On the bottom part of the phone, we have three ports - one micro-USB port, one speaker, and a headphone jack. This makes it easy to connect the phone to external devices like headphones or speakers. One thing to note is that the phone does not come with a 3.5mm audio jack, making it unsuitable for those who prefer wired headphones.
The Oppo A57 also comes with a power button on the right side of the device, which is accompanied by two volume rockers and a home button. The home button is unique in that it doubles as a fingerprint scanner, making it easy to unlock the phone or make payments using mobile wallets.
**Camera Performance**
One of the most impressive features of this phone is its camera performance. The 13-megapixel rear-facing camera takes excellent images with good brightness and contrast. However, the image quality can vary depending on the lighting conditions. The selfie camera, which has a higher resolution than the rear-facing camera, takes excellent selfies with good color accuracy.
In our testing, we found that the phone's camera performance was on par with some of the high-end smartphones in its segment. The selfie camera took some of the best selfies we've seen from any smartphone, making it an excellent option for those who want to capture high-quality images and videos.
**Software**
The Oppo A57 runs on a custom Android UI called ColorOS 3.1. This operating system is designed by Oppo and offers a range of features that enhance the user experience. The UI is clean and intuitive, making it easy for users to navigate their way around the phone.
One notable feature of this operating system is its lack of an app tray. Instead, all apps are displayed on the home screen, which can make navigation faster but also more cluttered at times. However, Oppo does offer a folder feature that allows users to organize their apps and create shortcuts.
The Oppo A57 also comes with a range of software features that enhance the user experience. These include a Compass app, FM radio support, and quick toggles for frequently used features like Wi-Fi, Bluetooth, and screen brightness.
