Earlier today I was having trouble getting the hot spot to connect. I was getting a screen with a revolving pinwheel but no screen to check on the hot spot. Later it started connecting again. Then later tonight I tried to disconnect the hot spot and it would not disconnect even by turning the phone off, I had to pull the battery. Now it wont connect at all in fact when you touch hot spot I cant even get the phone to give me the hot spot activation screen all I get is a click but the screen wont change into the activation screen so now I have no hot spot at all. I tried a master reset and no luck fixing it that way either. Someone at Android Central forum is also having the same exact issue.
