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??
Perhaps you can uninstall and reinstall the Facebook app? Maybe you have an "Enter or Return" key on your keyboard you can tap in place of an actual OK/Enter button under the login info.
