I noticed a problem with my widgets on my Android rig where the app widgets were not showing up.

This was my problem since I had just moved all of my apps the SD card to save space.

Fix 2

Sometimes the Home screen data may get corrupted.

You will have to reset the Home screen data and start fresh.

These steps will reset your icons on the Home screen back to defaults.

The Home screen should be restored, along with the ability to use widgets.
