Display
The 3.5-inch TFT display of the Sidekick 4G has a resolution of 480 x 800 pixels, offering a relatively sharp image at approximately 267 pixels per inch. Although its screen-to-body ratio of 45% seems low by today's standards, at the time of its release, it offered a decent viewing experience. While not comparable to modern displays, it was more than sufficient for browsing, messaging, and media playback needs of early smartphones.
