Just to let you guys know, if you don't already. I work at VZW Tech Support and we currently have a nationwide outage on the 4G Mobile Hotspot app on the Samsung Charge. I noticed the issue yesterday on my Charge, where I will tap on the application and it will force-close immediately back to my home screen. The issue has been escalated and being looked into it, but unfortunately, no ETA at this time.
We have been told not to make any tickets for this issue to our NRB (network repair bureau which handles network outages) nor ITSC (handles outages such as our website) since they are already aware of it. So unfortunately if you do call in, there is very little we can do here. Its just a wait and see right now.
