Taking a picture from Dynamics 365 mobile app and attaching it on the timeline at the same time is now possible.
We will just have to enable few setting from mobile app. Here are the step to follow:
Login to the mobile app using admin credential and go to Setting –> Mobile Setting
Below screen would appear after clicking on Mobile Setting. Enable Allow Access under Camera. If we want to save the picture taken from the phone into the phone gallery then, we also need to enable Save Photo to Library option. Hit the OK button.

Now. let navigate to Opportunity. I have opened a record under opportunity.
Open an opportunity record Select Timeline option
Hit the Camera icon Hit the check icon for attaching the snap on timelime
Add Title and Note for detail info. Hit Add note button. Activity got captured under timeline.
Now, we see that the note has got saved under timeline of “Adobe Opportunity” record .
