I've installed iOS 7 GM today and been very happy and impressed so far. However I'm starting to notice extremely annoying elements of the one minded minimalist approach that Jony Ive has produced.
In fact in design terms these ideas aren't progressive at all. They are a regressive approach in fact and make no sense.
One example is the dial pad, something that's at the heart of the iPHONE (a PHONE primarily). In all previous versions of iOS, when you made a mistake dialing a number, the delete button was not only accessible in terms of positioning on the UI but also big enough to be easily pressed and noticeable.
This takes a step backwards in iOS 7 where now it's so small and out of the way that it makes it a nuisance to use.
Another example is the extreme minimization of other UI elements such as the delete button in the camera/phone app. I don't have giant hands by any means but I found that it's so close to the edge of the corner and has been smooshed as much as possible that it makes misclicks quite common.
It's very strange to me that Jony Ive comes out as this knight in shining armor in his genius design re imagining of iOS yet fails to hit the mark on the small details.
If you look up a business on Yelp, Maps or Safari you will most likely find a phone number hyperlink to call. People you call often would be in your contact book. Who manually dials numbers these days?
The delete button only shows up when you actually enter a digit. When else would you be looking for it? makes perfect sense to hide the element when it is not needed.
