Oppo A31 2020 Specifications, Price and Release Date

Oppo has just presented its newest entry model with simple specifications, interesting battery and great price on the Indonesian market: the Oppo A31.

The device arrives with hardware models offering an Helio P35 chipset from MediaTek, with only an option of 4 GB of RAM with 128 GB of internal storage, still allowing expansion via microSD. The A31 is now available and has an Android 9 Pie operating system and ColorOS 6.1 interface.

Among the main differentials of the cheap Oppo is it's 20: 9 aspect ratio, higher than that used by the brand in previous years and which is already approaching the final format of 21: 9 that should become popular from 2021, aiming to offer more space for scrolling content and better viewing movies in such an aspect.

The device offers three simple rear cameras: in addition to the main sensor of 12 MP, Oppo offers a sensor of 2 MP with the lens for photographs in macro mode and another sensor of 2 MP for the depth of field data, not allowing great versatility since it does not feature wide-angle or telephoto cameras.

Oppo also implements the 4,230 mAh battery, but unfortunately, the model still offers a micro USB connector in 2020 instead of USB Type-C. The headphone connector is also present in this model.

Price and Release Date

The Oppo A31 is available in Indonesia in the colors Fantasy White and Mystery Black for the price of 2.599 billion Rupee Indonesia, or 190 dollars in direct conversion.
