i used to use an iphone 4s well after its release, and my friends -even the ones who have brand-new phones- used my phone to take photos, selfies etc. iphone has a good technology for photographing which makes their phones better, even with lower megapixel values.
good photos btw!
thanks
Hello, I have a iPhone 6 right now, better pics, better phone but indeed the old ones are still acceptable, even with the lower mp as you mention
