Phone dialer app: The phone app now includes the ability to look up contacts directly from the dial pad, see and tap frequent contacts, and search corporate directories easily.

Focus and exposure: The “touch to focus” option has been enhanced with a new circular on-screen control that can be dragged by a finger around the viewfinder to adjust a photo’s focus and exposure.

Gallery app: New photo editing options are now available in the Gallery app, including new filter effects, the ability to draw on your photos, advanced cropping, and adjustments for color, exposure and contrast, among others.
