Display
Featuring a 6.51-inch IPS LCD screen, the Vivo Y21s offers a decent display size for a wide range of activities, from streaming videos to browsing the web. The resolution stands at 720 x 1600 pixels, delivering an average pixel density of about 270 ppi. While this may not reach the sharpness of higher-end models, it provides a satisfactory viewing experience given the phone's target market. The screen-to-body ratio of approximately 81.8% ensures a spacious display area, while maintaining manageable bezels.
