Android Central just outlined a very simple way of getting rid of those very pesky empty Album folders sitting in your Gallery app. All it involves is heading over to the Picasa Web Albums page and deleting those folders.
Even if those folders had been deleted from your Google+ albums they would still show up on your phone and they just didn't look good. This trick will also allow you to get rid of duplicate folders.
