This appears to be a problem with Samsung’s Touchwiz Launcher. You can easily get rid of this issue by clearing data from TouchWiz Home. However, keep in mind that it will reset your entire Home screen and launcher settings back to their defaults. – From the Home screen, press Menu and select Settings. – Select the More tab and choose Application manager. – Select All tab and scroll down and select TouchWiz home. – Tap the Clear data button. This should reset Touchwiz when you restart the launcher. Now if you tap the App Launcher, all of your installed apps should appear.
