I got an Optimus G about a week ago.  It's running the default software with whatever OTA updates I was able to install (4.0.4).  So far it's been great, but today it quit recognizing input from part of the screen.  I've attached a screenshot (I can't touch the bottom left).  I tried a factory reset, but it didn't help.  Is there anything else I can do that might get it to start working?
