I recently inherited an LG Apex. Although no icon show up anywhere, when I go to settings/manage applications/all, there is an icon and it says "com.lge.LgHiddenMenu". What is this? All I can find via google searches is how to set up a hidden menu,nothing on how to open it and see what's in there. Is there a standard key entry that I should try to see if it opens up? Any info on what the hidden menu is or how it works would be great. There are a lot of other apps that have been installed on the phone, but aren't showing up anywhere except for under the settings/manage applications/all.

Thanks!!
