These are India-specific displayed store prices, not guaranteed final transaction amounts or global prices. Prices and availability can change. Although the pages list additional storage configurations, the cited figures do not establish prices for every variant.
Which phone has the better display?
The S2’s listed 6.83-inch AMOLED panel has a 2800×1260 resolution, while the Y31 uses a 6.68-inch, 1608×720 LCD with a refresh rate of up to 120Hz. The S2’s specifications point to a sharper AMOLED panel; the Y31’s listed advantage is its high refresh-rate figure. Resolution, panel type, and refresh rate describe different attributes, so no single figure establishes which screen will look or feel better to a particular buyer.

Battery and charging differences
vivo lists a typical battery capacity of 7,050mAh for the S2 and 6,500mAh for the Y31. Both list 44W charging. The S2 has the higher stated capacity, but capacity alone does not establish which phone lasts longer: actual runtime depends on use and other factors, and the cited pages do not provide a comparative endurance test.
Camera hardware: what the specifications tell you
The S2 lists a 32MP front camera, compared with 8MP on the Y31. Their rear camera listings also differ: the S2 has a 50MP main camera and a 2MP secondary camera, while the Y31 lists 50MP and 0.08MP rear cameras. These figures describe listed hardware, not image quality. No independent camera comparison is established by the cited sources.
