Hi everyone, I am using galaxy note 5. I am looking to some basic understanding of how Gallery app & Camera app works. Additionally, I backup my pictures to Dropbox. This all is creating duplicate pictures and it is driving me crazy. Camera app: is showing not just the pictures I take with my phone but WhatsApp pictures and videos. Why this happens and how can I set it up to see only the pictures I take and not the WhatsApp pictures and videos. Gallery app: Now I know little better than by using this app you can see things in different folders such as Camera. Also what I have noticed is that not all WhatsApp pictures and video shows up in pictures under gallery. Dropbox backup: why the backup doesn’t synchronize when I delete the pictures and video from Dropbox back the phone and vice versa. Thanks for your help as I am tired of clean up my pictures and video on my phone and Dropbox.
