Google Hangouts is getting iOS CallKit support, a couple of bug fixes1
Hangouts 16.0.0 is already available for download via App Store. The new app brings support for Apple's CallKit, which enables VoIP services to make and receive calls using the iPhone's dialer and phone app.
The new feature can be enabled or disabled from the Settings menu by tapping the Answer option on lock screen. After the update, users will be able to make calls using Siri commands, while the stock iOS call UI will allow them to receive incoming calls.
Aside from the options to receive incoming calls and make outgoing calls using the default phone app, the update includes a couple of fixes.
For starters, the update is supposed to address the photo pinch zoom in preview issue that many users have reported about lately. Lastly, an issue that would crash video calls should be fixed as well.
