Just got this from DropBox

" Congrats on becoming a Dropbox Guru! We've awarded you 48 GB of bonus space for the next 24 months. You now have 50.25 GB on Dropbox. To get even more space, check out our upgrade options. Thanks again for supercharging your Samsung device with Dropbox!  

Now why didn't they offer me that a couple of months ago before I started to use Google Drive with all it's problems.. 50 Gig is not to be sneezed at though...
