I recently purchased a smart phone thunderbolt it is my first smart phone which I use as a laptop. This morning the phone was frozen and I had choices on what to do, reboot was one of the choices, I couldn't figure out how to reboot the phone until I used the volume button to highlight choice and used the power on button as an enter command. I did (do) not have a clue as to what I needed or want so I just rebooted and the system restarted. What happened? I initially thought I may have contracted a virus ( I have AVG paid version) I have been playing with the phone to find out all of its functions where do I go from here?
