I know such solutions exist, but I expect that the phone's camera can hook deeply into Windows, so that any app can capture everything the phone's camera captures. In OneNote, for example, I want to be able to easily "Insert Picture from Camera", but instead of using SP3's internal camera, it automatically connect to the phone's camera.Since I have an Eye-Fi device (even though I'm not using it with my current setup) I've got this working with my Android (Galaxy Note 4) and my SP3. I have installed the Android Eye-Fi app on my Note 4 and Eye-Fi Center on my SP3. Whenever I take a picture with my phone (as long as my phone & SP3 are on the same WiFi network), the picture gets automatically transferred from my phone to my SP3.
I think you may need a registered Eye-Fi card to get this to work, but I may be mistaken.
Another option is to sync your phone's pictures with a cloud service that also syncs with your SP3. This solution might take a few minutes for a sync to complete and the pictures to get to your SP3.
