The display is the primary interface for user interaction, and differences in screen technology and specifications can significantly impact the visual experience.

• Display Technology and Resolution: The Galaxy S21 5G features a 6.2-inch Dynamic AMOLED 2X display with a resolution of 2400 x 1080 pixels, resulting in a pixel density of 421 pixels per inch (ppi). The iPhone 15 Pro has a 6.1-inch Super Retina XDR OLED display with a resolution of 2556 x 1179 pixels, offering a higher pixel density of 460 ppi. Both displays provide vibrant colors and deep blacks.
• Refresh Rate and Brightness: Both devices offer an adaptive refresh rate of up to 120Hz, contributing to smoother scrolling and more fluid animations. The Galaxy S21 5G reaches a peak brightness of 1300 nits. The iPhone 15 Pro offers a typical maximum brightness of 1000 nits and can reach up to 2000 nits for outdoor peak brightness, providing better visibility in bright conditions.
• Additional Screen Features: The iPhone 15 Pro includes Apple's Dynamic Island, an interactive area around the front camera and sensors that displays alerts and background activities.

Camera capabilities are a significant factor for many smartphone users, with both devices offering advanced systems for photography and videography.
