Disappearing Icons on Galaxy S2 On my Samsung Galaxy S2, sometimes all of the icons will disappear from the home screens except for the 4 built in icons (phone, messaging, web, applications). This sometimes happens at startup, and sometimes happens after the phone has been running for a while. It can only be fixed by rebooting the phone, although that is not a guaranteed fix.

More recently I've encountered an additional problem: Sometimes when the icons disappear, the Applications button stops bringing up my applications menu.

Any suggestions on how to fix this?
Just a thought based on what I experienced.
I saw icons disappearing on an Android tablet, when I move the apps to SD card or apps installed on SD card instead of internal default flash memory. Are these apps installed on an external SD card? if the SD card is not initialized when the home screen becomes active, they may not be available.
