Is there a feature where when you or the app uploads the photo to drop box it then removes it from the phone.
No. The Camera Uploads feature doesn't delete photos or videos from your device. Likewise, deleting a file in the Dropbox app won't delete it on the device, and deleting a file on the device won't delete it from the Dropbox app.
The mobile apps do not sync in that manner.
