Oh look. They improved the camera each generation. Must be because of some camera bug users were complaining about. Same for the screen. And processor. Etc. etc.....
They improve phones to make them better. Not because of some inherent guilt you think they have...
I am really tired of all these excuses from Apple apologists.
Until recently, iPhones shipped with no so decent cameras, but that didn't prevent the phone from being used as intended.
