Samsung Galaxy M55

  • Strengths: The M55 is a mid-range powerhouse, boasting a vibrant AMOLED display with a 120Hz refresh rate, a powerful processor, a high-resolution camera, and fast charging. Its superior performance and features make it a much more capable and enjoyable device.
  • Limitations: It is more expensive than the C21 Plus and lacks expandable storage, which could be a concern for users with large media libraries.
