Hi all. I can't seem to make my Samsung Galaxy S3 turn into a mobile hotspot. The phone is rooted. When go to turn it on, it waits for a few seconds, then gives an error message. Which is: Unfortunately, settings has stopped. And that's all you get. You have to click ok, and the windows closes. Wifi hotspot is left off. My carrier is AT&T. My android version is 4.1.1 What exactly is going on here?
