Display
The Celkon C20 sports a 1.8-inch TFT display with a resolution of 128 x 160 pixels. Although the screen occupies a modest 20.5% of the body, typical for phones of its class, it serves well enough for basic text and graphic outputs. The 114 ppi density might not offer high-definition clarity, yet it ensures sufficient readability for most standard tasks such as viewing SMS, checking call logs, or playing simple games.
