I have a error message that pops up frequently that says " enter password for "" Facebook settings ". It just pops up randomly on my screen irregardless of what I'm doing. I go into settings and it allows me to type in password but nowhere to hit enter it seems like it's locked. I have taken it into local Verizon stores and no one seems to know what the issue is or how to fix it. When it pops up I have to hit cancel in order to continue what I'm doing on my phone so sometimes it's an annoyance. Any ideas as to what the issue might be??
