Google has released an update to the Google Camera app for Android devices that, effectively, is the camera app that will be in Android N. It brings a wealth of new features including the ability to take stills while recording video. The update is build 3.2.042 for those keeping score at home and it has been released into the Google Play Store. If you have the app installed, the OTA update should come to you in the next few days.
The ability to capture photos while shooting a video is not something new to Android and in fact was a feature in the default Camera app for a long time. At the end of the Lollipop days it was
removed but has finally made its way back into the app. This is something that other camera apps have been able to do for a while so it is good to see Google get it back into their app.
Slow motion is now a separate pull-out menu rather than a button in video mode with this update and you will also notice that the shutter button and the front/rear camera swap icons have been updated in this release as well.
While Google did not officially indicate that this update to the Google Camera app is that of Android N, functionally it is identical to the camera that is in the technical preview. That is what is leading most to the assumption.
For those who do not have the Google Camera app and want to give it a try, you can download it here from the Google Play Store.
