I think many people here want a dark mode for iOS but what if Apple decides to make that an exclusive software feature of the iphone 7. Apple does have a history of highlighting a new feature done via software that is exclusive to new hardware. For example the iphone 6S has 'selfie flash' which can easily be done on any other iphone, but they choose to make it exclusive to 6S to make it more appealing . So " Dark mode" is another feature that can easily be done on any phone, but maybe just maybe Apple is holding this feature back to be an exclusive feature for the iphone 7. Would this upset you? Do you think it's likely? The iphone 7 can have a tweaked version of iOS 10 that which has a dark mode that can't be run on other ios 10 ready phones so it might happen.
