I have tried all the online known fixes for this issue , clearing data, restarting phone, removing all other camera applications, and still cannot get my front facing camera to work on my Thunderbolt. As soon as I select the front facing camera, the application closes-without any error message-and brings me to the home screen. What is going on? I was able to use it this Spring, and then all of a sudden I can't use it anymore. Please help.
