In ios 7 i dont find how to close the apps which i open and they are at background? Another thing is adjusting the brightness and volume with Home button not found.does it change?if Yes then how it works now?
On the contrary, Apple is so innovative that some people need to have their minds opened to the functionality. Specifically all the gestures you can use. For many these are intuitive but they don't think of the shortcuts.
Add to that the fact that there are so many people out there that insist on a users guide because in the past they needed one to understand how Windows worked.
