Yes! but not only sensor. the lenz size also matters. if we go little flashback it's Nokia camera Phones. with bigger cameras like i personally use Nokia 3650, 6600, N71, N95. and all of those have a big lens camera take large place in phone. but picture are more good as compare many or those days smartphone cameras. that time mobile cameras only touches 3MP to 5MP and normally just 1.5MP to 2MP cameras in regular phones. so as compare to this i conclude that it is just a trick to capture market. on fake ways. where you publish something as a bigger and best from others and when you buy. it has lot of bugs. and mobile companies knows that this generation love to take selfies. so they sales there products with the name of selfie experts. and so on ....
