iOS has been redesigned, from the app icons and colors to typography, buttons and the general outlook — everything is simple and clean.

New filters have also been added to the camera app on top of the basic editing features that is already available.Zooming out again then shows you the photos taken, sorted by year. It can roughly tell you highlights of each year like you visiting another country for holiday. You can then tap, hold and swipe your finger across the small pictures for a quick view.
7. Siri & iOS In The Car
Siri is now smarter with integrated Wikipedia and Bing support built in for your search queries. There’s also Twitter where Siri can check out what your friends are saying. Other than Siri’s new look with the soundwave, it now shows results in a cleaner way.Siri now also has a male voice, and can speak to you in French or German (more languages coming soon). Voice commands are also available for actions like "play my last voicemail", "turn on Bluetooth" or "increase brightness".
