Photos from the camera roll can be synced from iOS to OneDrive and from a lot of other devices. If i work on the photos and delete some i.e. on my Computer, then the Photo gets also deleted on OneDrive. Unfortunately this is not working for the iPhone. There you have to go and manually delete the photo a second time, which is very annoying.

Perhaps you can implement something like "Autosync for OneDrive - OneSync" which does a greate job on Android
