Display
The Vivo Y31 sports a 4.7-inch IPS LCD display with a resolution of 720 x 1280 pixels. The screen’s pixel density of approximately 312 ppi provides decent clarity, especially for a device in this price range at its time of release. While the screen-to-body ratio of about 64.5% might not seem impressive by today's standards, it provided a satisfactory visual experience for basic multimedia consumption, browsing, and social media usage back then.
