Oppo A57

Oppo was among the top 5 successful brands of Bangladesh in terms of generating revenue. Oppo is bringing Oppo A57 as the first smartphone in 2017 in Bangladeshi market to continue with its rising popularity. Among the strong reasons behind Oppo's popularity is its product quality, attractive pricing, quality branding and dedicated service. These should be included with A57. In terms of feature, this device is not among the high premium phones. HD display and snapdragon 435 chipset can't be considered as premium features. But other features like 13 + 16 MP great quality camera, 3 GB RAM + 32 GB ROM, OTG, fingerprint sensor, 4G network support, Octa-core CPU and adreno 505 GPU represents a well made smart machine. If you can compromise on the relatively lower quality HD display (Full HD would have been perfect) and smaller 5.2 inch display (5.5 inch is popular these days for watching videos and gaming), this can be a highly considerable choice for the price.
