The reviewer mentions that the auto rotation must be found in the Settings Menu. I found that to be so, and that it was not enabled in Settings, but there is a button which flips up or donw on the (outside) left side of the tablet if viewing in Landscape orientation, that allows the tablet to auto rotate. It appears to be an easier access point than going into Settings.
While I am writing, for those who aren't aware of where the SD card slot is, it's under the speaker/rear camera access panel. You place each hand on the portruding tiny nodules sticking out and then gently push on the nodules in an up and out/away movement. The panel is a thin plastic so don't push too hard. You do not need any screwdrivers or implements to remove this panel, only a small bit of pressure. There is a tiny 1/4" slot at the top of the tablet that looks like you insert some kind of tool in to remove the panel but that is not where you remove it from. The 2 tiny gray nodules on either side are what you place your fingers or fingernails under to remove the panel. The SD slot is on the left.
This tablet seemed to support the fee sites for books. But by going to Settings/Security/ then see Unknown sources and saying OK in the pop up winder, I was able to download the site 10,000 eBooks which is a totally free book site-nice. After downloading my source I went back and disabled Unknown sources.
