DropBox Delayed Upload How long does it normally take for Dropbox to upload photos that I take on my camera?
I took some photos on Saturday and then my phone suddenly stopped working on Sunday. I keep checking my Dropbox online and it still hasn't uploaded. I have a Galaxy S5.
Oddly enough I just enabled it and tested, instant. Now I apologize for the 'answer', I cannot comment. 

First we need to ensure that you're uploading is not set to WiFi only, and you're trying to upload via mobile data. That would be a painful issue. 

Now if you have Auto-Sync on, it will usually run at the next set run. Possibly try clearing cache (within the app) and try again, it should spark Drop Box to recheck. If you're really enthusiastic, unlink your device, go to settings, clear data and re-login. 

Once again, apologizes, I'd prefer to comment.
