I have a Galaxy Tab 10.1 that I guess I have never updated the Android version. It is currently 3.2 and I NEED to update it to the current version for the primary software I use on this tablet. But when I go to "Software Update" and click on "Check for Update" there is a pop-up that says "Checking for Updates" and that's as far as it gets. Eventually it just times out and that's it. No update. No offer to update. It just stops. Any thoughts??
