So with every purchase as far as I know of a Samsung phone, you get a certain amount of Dropbox space for free for two years. Well I used it first on the s3. So now my two years is up...is there anyway to add the two years from buying the s4 and then s5 onto your account to keep the extra space for free onto your first account or do you have to make a new one each time? Sorry if this was already posted.
