I have my Flickr account linked to my Android phone, through the Flickr App. Makes it really simple. The only issues I had, when I started using the Flickr App. after having my Flickr account for several years was, when I'd upload mobile photos, for some reason, they defaulted to a private folder, even though my entire Flickr acct was NOT private...lol. For videos, you can do the same thing, through a Youtube App.
Oh, one thing to keep in mind, if you want to keep some sense of privacy, is to turn off Geo tagging. Otherwise, with a lot of the newer smart phones, your GPS location will be embedded into photos that you take.
