The updated version (1.65) of the Android WMD app offers a new feature. With a finger tap you can backup your Android device Contacts to the WMD internal memory. The action to backup works well. However when I checked the WMD device memory and tapped on the backup file, the contacts were imported back to the Android device creating duplicates. I tapped twice before I realized the import was happening. My Android device has no abilty to merge duplicate contacts or mass delete contacts. I had to delete one by one the triple entries from my Contacts.
There should be a reminder message with a yes or no response confirmation when the backup file is accessed on the WMD. Otherwise this is a nice to have feature, for folks who do not trust a cloud backup of contacts.
