My phone is a Samsung Galaxy Note 3, using Android 4.4.2. No mods or rooting. I first noticed the problem in image viewer F-Stop which began showing many images as two thumbnails, with different tags, but still the same image. After tracking down the problem I found that my phone now not only has a "download" folder on the internal storage card, but also has a "Download" folder as well. This can be seen in any file manager and even in F-Stop or Gallery when looking at a folder list. Inside each folder is an identical list of files, but I don't think that the files themselves are duplicated. Each time I download a new file, it shows up in both folders, and the same when I remove a file, it is removed from both folders. This hasn't been a big problem except in F-Stop which has become very slow because of having to scan both folders, and the duplicate thumbnails is screwing up my tagging of the files. I don't recall any particular events that happened around the time this problem started so I can't narrow down what program or action might have caused this. I am also afraid for deleting one of the folders in case it ends up deleting all the files with it, or doing anything with any of the image files in case it gets rid of their tags. Any ideas?
