1. If you have been used Worldscope Widgets , please uninstall. You do not need this app anymore. It is integrated in Worldscope Webcams now.
2. make sure you have installed Worldscope Webcams to internal memory. If the app is installed on SD card, widgets, wallpaper and timelapse recording will not work. This is due to Android OS limitation.
3. Add the widgets to your homescreen.
