There is a common issue for Android users where the shortcut icons disappear from the Home screen. This has been happening for Motorola Droid users since the Froyo 2.2 update. That update is when the option to move apps to the SD card became available. The problem appears to be linked to that feature. Apps that are moved to the SD card are the ones that have shortcut icons missing from the Home screen. Since the phone boots and loads the home screen before the SD card is mounted, it misses those icons and doesn’t load them on the screen.
To solve this issue, you’ll have to move the disappearing apps back to the memory of the phone or device and off the SD card.
1. Open Settings.
2. Tap Applications.
3. Tap Manage applications.
4. Choose the app that goes missing from the Home screen.
5. Tap the Move to phone or Move to device button.
If you have a ton of apps moved to the SD card and don’t want to go through the trouble of moving all of the apps back one-by-one, there is an app in the Android Market called Advanced SD Card Manager that will bulk move the apps back to the device.
