Yesterday after charging my phone this appeared on my screen and I cannot get rid of it. I have popped the battery out a few times but it does not help. Can anyone offer any help? Warning! I am not much of a tech person. Otherwise I will drive out to my local Verizon store today.
Here's a thought if you have not been to the VZ store already. Go to Menu>Settings>About phone (at bottom of the list), and then press System updates at the top of that list of items. Does it say, "Your system is currently up to date?" If so that's okay otherwise it might start a system download. If it starts a system download then you have found the problem with regard to the message you locked on your screen.
OTOH, if your phone is completely locked up you were right in the first place, do not pass GO but go directly to the Verizon store.
