Apple also added Voice Isolation for cellular calls which should offer improved ambient noise reduction. The feature was previously available on FaceTime and other third-party VoIP call apps.

There’s a total of 21 new emoji symbols with the new iOS release including hand gestures, pink heart, jellyfish and a Wi-Fi symbol. Photos get a neat feature that can remove duplicate photos and videos across iCloud Share Photo Libraries.
