My Companion App works completely fine on my Galaxy S4 phone. But like I've seen other's post, I am having an issue where my character is completely black and void of any detail on my Galaxy Tab 3 in the Companion App. (Weapons and Armor as well). I don't believe it has ever worked on my tablet, and I have had the app since the game launched. If it was working, It was for a short amount of time right after launch.
