Editorial note

The Oppo A57s stands out with its 6.56-inch display that offers a pleasant visual experience, although its resolution of 1612 x 720 pixels may not satisfy the most demanding users. The sleek design in Starry Black color is attractive, but it may lack originality in a market saturated with smartphones. In terms of performance, the MediaTek Helio G35 processor ensures smooth usage for everyday tasks, but shows limitations when tackling more demanding applications or resource-hungry games. The 4 GB RAM capacity may also not be sufficient for users engaging in intensive multitasking. Regarding photography, the 50 MP rear camera and night mode allow for capturing good quality images, although the limitation to a small number of sensors may reduce shooting flexibility. The 5000 mAh battery is a strong point, providing excellent battery life for daily use without frequent recharging. Although the product has an IPX4 rating, its lack of protection against dust and water beyond this level may be a drawback for users seeking a more robust device. In terms of value for money, the Oppo A57s represents an interesting option, even if it may not meet the expectations of users looking for superior display quality or more RAM.
