I have enjoyed lurking on this forum for the past week after I received a tablet for Christmas--lots of great information available. My tablet was advertised as an Allwinner a13 with 4GB storage and 512MB ram, but under the android storage settings, only 2GB is listed--one internal and one on an sd card. I downloaded a couple of apps to check hardware and they only report 2GB storage and only 350MB ram. Could some of this storage or ram be hidden and therefore not recognized by apps? Thanks for any help.
