    Still not true android. Much to much at@t bloatware.
    Would like to see the sm-n900a with unbranded 4.4.2

    • Flip Jumpman

      You can get rid of the bloat simply by turning off/disable all the at&t and Samsung apps you don’t use.
      What is “True Android”? Just curious to know your thoughts…
