The update that is supposed to happen will consist of the following features:
- New full-screen notification mode along with navigation areas.
- Battery improvements.

Some other little fun features will be coming too like cloud printing, emoji, better music controls in lock screen, and Tap & Pay for paying securely through NFC.
To get the update go into Settings>General>About phone>Software Update>Update Now. The update is 686MB in size and shouldn’t take up too much of your space. The update is rolling out now. Hope you enjoy it!
