Remo Duplicate File Remover app is designed to delete duplicate files on your device. However, all of your contacts are stored in a single file and not stored as one contact per file. Duplicate entries of contacts are made on to the same single file. Remo Duplicate File Remover can only detect identical duplicate files, since all the contacts are stored to a single file there are no duplicate files created in the first place.
