The verykool s4009 Crystal, announced in June 2017, is a budget-friendly Android smartphone designed to cater to basic mobile needs. Here’s a summary of its key specifications:

  • Display: The device features a 4.0-inch display with a resolution of 480×800 pixels, providing a modest screen for basic viewing and interaction experiences.
  • Chipset and RAM: It is powered by the MT6570 chipset and comes with 512 MB of RAM, which is suitable for very basic tasks and light usage. Users should not expect high performance, especially with more demanding apps or multitasking.
  • Storage: With 8 GB of internal storage, users have some space for apps and media, which can be expanded via microSDXC, making it somewhat flexible for storing photos, music, and videos.
  • Cameras: The s4009 Crystal is equipped with a 5 MP primary camera and a 2 MP front camera, offering basic capabilities for capturing photos and video chatting.
  • Battery: It has a 1200 mAh battery, which is on the lower end, indicating that the phone might require frequent charging, especially with moderate to heavy use.
  • Operating System: The phone runs on Android 6.0 (Marshmallow), an older version of Android, which means it may not support newer apps and features but should still offer access to a wide range of applications and services available for the platform.
