Just got a Sony Tablet S and have done the usual thing of linking gmail account, adding and updating apps, etc. While doing this if ran perfectly, however after I turn it off and turn back on it has gone into a perpetual reboot (get to main screen but before I can do anything it reboots) I did a factory reset and tried again but am getting the same result. I even tried creating a new google account but same issue. The tablet has had a firmware upgrade, etc through the normal updates (I don't know how to root it so it has not been modified). Was wondering if anyone has experienced this and can offer any suggestions to fix.....quite frustrating as its a nice little tablet.
