A few months ago I got my hands on a Samsung Galaxy S4. As part of the setup procedure it asks for your login details for Dropbox, this was great, I actively use Dropbox, had the app on my previous phone and regularly access files from my cellphone. As it was set-up on my previous phone to only download files when I request/access them, I expected the same to happen with this setup.
The next day I checked my gallery, and saw hundreds and hundreds of photos that Dropbox had decided I wanted to have on my phone. Fortunately I was on Wi-Fi, otherwise that 1.5Gb could have hurt my phone bill at the end of the month. This wasn’t a major problem, as I assumed I’d missed something in my settings which told it to sync photos, so I went in search of the correct settings. And I couldn’t find them anywhere.
I compared the settings exactly to that on my previous Android phone and there was no difference. After searching for a quite a while on the internet, I eventually came across a forum post that explained my problem. The setting I was looking for wasn’t in Dropbox, it was in my phones ‘Accounts’ options, and not under the Dropbox account, but under the general ‘Cloud’ options.
If you look at the bottom you’ll see a ‘Contents sync (with Dropbox) menu, here you can disable the syncing of pictures, videos and documents. Disabling this option then removed all my photos from my gallery and prevented the further unwanted syncing of files from Dropbox to my phone.
So to get there:
Settings > Accounts tab > Cloud > Contents sync
