I am running Android version 4.0.4 which has a different method of adding widgets and app icons to the home screen.
When you tap and hold a position on the screen, you get a menu that only allows you to change the wallpaper.
The new method has you select All Apps and scroll thru the apps to an area that has existing widgets, then drag them onto the screen,
There is a Tasker widget but I can't make it do anything.
Thanks for any help.
