I never said it did. I said that it's up to a developer if they want to support older hardware or software. The fact that they chose not to may have nothing to do with programming competence and everything to do with economics. Whatever the reason, WhatsApp choses not do support the phone you have.
And, yeah, comparing an iPhone 3G and a Samsung S6 (a phone that is not doing nearly as well as Samsung had hoped, by the way) is like comparing a '57 Chevy to a 2015 Chevy Impala. It's just a silly comparison.
