I have PandaHome installed on my phone. All of a sudden, any time I go to the home screen, the word "case" appears in the middle of a transparent black background. This occurs at the bottom right corner of the screen. It eventually disappears, but if I open an app, then go "home" it reappears for approximately 45 seconds. I have not installed any new apps. This suddenly started to happen.
Any help would be appreciated.
