Comparisons Featuring verykool s4009 Crystal

Short Review

  • The verykool s4009 Crystal features a compact design with dimensions of 127 x 66 x 10.7 mm and a weight that enhances portability.
  • Its 4.0-inch TFT display offers a resolution of 480 x 800 pixels, resulting in a pixel density of approximately 233 ppi, suitable for basic tasks but lacking HDR support.
  • Performance is driven by a Mediatek MT6570 chipset with a dual-core 1.3 GHz Cortex-A7 CPU and Mali-400 GPU, paired with 8GB of storage and 512MB of RAM, which may limit multitasking capabilities.
  • The rear camera is 5 MP with a maximum video recording capability of 720p at 30fps, while the front camera is 2 MP, adequate for basic selfies.
  • Battery life is supported by a 1200 mAh capacity, but it lacks fast charging and wireless charging options.
  • Running on Android 6.0 Marshmallow, the software experience is relatively dated but functional for essential applications.
  • Connectivity options include Wi-Fi 802.11 b/g/n and Bluetooth 4.0, though it does not support 5G or NFC.
  • The device comes in black and gold colors but lacks water resistance features.
  • Overall, the verykool s4009 Crystal is a basic smartphone suitable for users with minimal needs.
