Access phone camera (iOS/Android)

The chat feature provided for both Android and iOS lets the user attach a picture from his/her phone gallery. However, there is no option to just take a picture and send it. That means that currently, in order to simply send us a picture, the user has to get out of our app, access the phone camera app, take a picture, and then go back to our app and select the picture from the phone storage.

Is there really no way to access the camera directly from within the chat window?
