Oppo A57 Specifications
Oppo is a famous brand especially among the selfie-obsessed Smartphone lovers in India. The Chinese handset manufacturer has consistently delivered impressive smartphones like Oppo F1, followed by F1 Plus and Oppo F1S with exceptional features and even better selfie cameras. In September 2016, Oppo launched A57, another great selfie-oriented smartphone in the Rs. 15,000 range in India.
The phone borrows a number of traits from the pricier Oppo F1s but is an upgraded version of A37 which came on the market in June 2016. As compared to its predecessor, A57 has a better RAM, improved processor, large inbuilt storage and more recent Android OS.
An Affordable Selfie Smartphone
• The Camera:
Probably the most important highlight of Oppo A57 is its 16MP f/2.0 front camera with auto-focus. The sensor of the front camera is highly competent and delivers detailed and sharp selfies. Even the pictures taken in low-lighting conditions as per the user reviews are very impressive.
Even the rear 13MP shooter has a host of features like LED flash, phase detection autofocus, panorama, and HDR. If you are someone who loves taking selfies and are looking for a budget-friendly smartphone, Oppo A57 is definitely a great option for you.
• The Display and The Screen
Apart from the cameras, the phone has many other equally impressive features. The phone has 5.2-inches IPS display with HD resolution of 720 x 1280 pixels and pixel density of ~282 PPI. While the display is protected with Corning Gorilla Glass 4, the phone comes pre-applied with a scratch guard. Moreover, there is an additional scratch guard included in the box.
Powerful Inside and Out
• Processor, RAM, and Storage
A Qualcomm MSM8940 Snapdragon 435 chipset and octa-core 1.4GHz Cortex A53 CPU powers the Oppo A57. It has an inbuilt storage of 32GB and 3GB RAM which can easily take care of most taxing phone activities. The storage can be extended up to 256GB with the help of a microSD card.
• Non-Hybrid Dual SIM Phone
Another notable highlight of the phone is that it features a separate slot for microSD card. While most budget smartphones now feature a hybrid SIM slot with which you can either use two SIM cards or one SIM card and one memory card, the separate slot for memory card in the A57 comes in handy.
• The OS and the UI
The phone runs on Android 6.0 Marshmallow and Oppo’s very own ColorOS 3.0. While this OS is significantly customised, it works pretty flawlessly without any major lags. Moreover, the company has also reduced the amount of influence its previous version of OS took from iOS. While you can still feel the influence, it is very subtle this time. It has a capacitive type home button on the front which also integrates the improved fingerprint sensor. You can also find the 3.5mm headphone socket and Micro-USB port at the bottom of the device.
• The Battery and the Connectivity
Oppo A57 has a 2900mAh Li-Ion non-removable battery which most of the users have agreed can last an entire day on full charge. However, there is no support for fast charging. Some of the key connectivity features of the phone include Wi-Fi 802.11b/g/n, Bluetooth 4.1, USB-OTG, FM radio and GPS. The phone supports 4G and VoLTE on all the Indian bands.
