Screen quality

The display is a primary interface for smartphone interaction, and both devices offer high-quality viewing experiences, though with distinct characteristics.

  • Display Technology and Resolution: Both phones feature Super AMOLED displays, known for vibrant colors and deep blacks. The Galaxy S9 has a 5.8-inch Quad HD+ Super AMOLED display with a resolution of 2960 x 1440 pixels, resulting in a high pixel density. The Galaxy S21 5G has a slightly larger 6.2-inch Dynamic AMOLED 2X display with a Full HD+ resolution of 2400 x 1080 pixels. While the S9 has a higher pixel count, the S21 5G's display is still very sharp for everyday viewing.
  • Refresh Rate and Brightness: A key difference is the refresh rate; the Galaxy S21 5G features an adaptive 120Hz refresh rate, providing smoother scrolling and more fluid animations compared to the Galaxy S9's standard 60Hz refresh rate. The S21 5G also offers higher peak brightness, making it more comfortable to view content outdoors or in bright conditions.
