Cheap Androids are not the preferred tablet, the Phantom controllers work best with Apple products, but if you're going to use an Android, get a decent one with a relatively fast processor. I went with a cheap one and am regretting it, it has video lapse and connection issues. My idea was to get a cheap/smaller one that I would use just for flying my Phantom 4. The smaller size allowed me to put it in the controller without the extender and I leave it in the case with the Phantom. I don't have any personal info on it, so I thought it would be great. I still use it, but I certainly would recommend getting a better one. I cannot tell you what is an acceptable one to get, I'm sure someone with more Android knowledge will. I'm just stating my opinion not to get a cheap one.
