What customers don't like about Oppo A57s (4GB + 128GB)

  • Noticeable lag during multitasking and app switching
  • Poor gaming performance; struggles with high-demand titles like PUBG or Genshin Impact
  • Display is limited to 720p (HD+) resolution rather than Full HD
  • Standard 60Hz refresh rate feels dated compared to 90Hz+ rivals
  • Underwhelming low-light photo and video quality
  • No 5G support, which may limit future-proofing
  • Does not include a protective case in the box

Verdict

The Oppo A57s (4GB + 128GB) is a budget-friendly smartphone focused on core features, powered by the MediaTek Helio G35 processor and running ColorOS 12.1 based on Android 12. It sports a 6.56-inch LCD display with a standard 60Hz refresh rate, and a large 5000mAh battery that supports 33W SUPERVOOC fast charging. A key pro is its 50MP main camera system, providing good resolution for the price, alongside dual stereo speakers for enhanced audio. The primary cons are the average display refresh rate, the use of a micro-USB port instead of USB-C in some regional variants, and the relatively modest performance provided by the entry-level G35 chipset.
