Hello brokemehphone... love your user name
. I'm guessing all you need to do is pull the battery out. Wait a minute and then replace it. This will cause the phone to do a reboot and that normally clears out such problems as you are experiencing. If that doesn't help, I suggest you check out the discussion area we have for your phone. If you don't find an answer... feel free to ask for help. Here is a link to your phone's discussion area: LG Optimus V - Android Forums
Have fun and thanks for using these forums.
