If they don't work than why the Android user retention rate is higher than that for iOS users? Besides, Apple has plenty f similar adds too. No one company is going to come up with an ad that lists all device features. That would be just stupid. Some people may be unsure what to buy. All Samsung is trying to do is to give them one reason to go with Samsung device. It also reminds people that Samsung is constantly ahead of Apple when it come to innovations. There is a long list of features that Samsung introduced first (or among the first) and Apple followe a year or more later: phablets, LTE, wireless charging, OLED, fast charging, pen support, large RAM, large batteries, NFC, barometer, sensor HUB etc (a very long list)
