About Oppo A57
The Oppo A57 is a compact Android smartphone built around a 5.2-inch IPS TFT LCD display with a 720 x 1280 resolution, delivering crisp visuals in a pocket-friendly form. Running on Android 6.0.1 Marshmallow out of the box, it balances everyday usability with modest hardware, including 3GB of RAM to keep multitasking smooth.
Housed in a slim 7.65mm chassis weighing just 147 grams, the A57 prioritizes portability without sacrificing comfort. Power comes from a 2820 mAh battery, offering enough capacity to handle typical daily tasks, while its single SIM configuration keeps the design straightforward for users who prefer simplicity.
This variant stands out with a larger 6.56-inch Color IPS TFT LCD display featuring a 720x1612 resolution, a significant upgrade from the base model's 5.2-inch screen. It runs on Android 12, offering a more modern software experience compared to the base model's Android 6.0.1.
The device also boasts 4GB of RAM, enhancing multitasking capabilities, and a substantially larger 5000 mAh battery for extended usage. Its dimensions and weight are increased to accommodate the larger display and battery, measuring 75.03 x 163.74 x 7.99 mm and weighing 187 grams. Unlike the base model and other variants, this version supports single SIM configuration.
