Display
Equipped with a 4.0-inch TFT screen, the Celkon A403 provides a viewable area that is sufficient for basic tasks such as browsing and texting. The display has a resolution of 480 x 800 pixels, which results in a rather modest pixel density of about 233 pixels per inch. While this may not deliver the sharpest images or texts especially by modern standards, it is adequate for everyday use, particularly in a device positioned at the lower end of the market.
