Better picture quality is indicative of a better camera, which would probably mean the phone cost more and that its owner is well-to-do.
Think about it: Are you subconsciously making dating choices based on something greater than your taste? When you look at a profile photo, for example, picture quality matters. However, on dating apps in India, there is a big chance that we are swiping left on people based on their social strata. Love that transpires organically often crosses the boundaries of caste and class. It could be fate, geographical proximity, similar interests or a mutual attraction that goes beyond what quote somebody chooses to paste in their bio. When we fall in love offline, there is a sweet back story alongside the many external factors that play a pivotal role in bringing the couple together.
