Do you use Droidwall? I don't know why, but Droidwall in "White list"
mode allows only the first packet of each transmissions of Webkey.
This might be the reason.
On the other way, pure_menu.html is used when the user doesn't have
the right to view the phone.html (which shows the screenshot). You
should check the permissions or create a new user with all
permissions.
Best wishes,
