It has been quite some time since I updated to ICS 4.0.3. Prior to the update, my stock TF101 was completely stable. Since the update, my home screen periodically goes blank. The shortcuts and widgets all disappear. Even the new app drawer shortcut goes away. I am left with only the wallpaper (live or not) and the notification bar. So far, the only way I have found to restore the system to normal is a complete reboot. This sometimes happens several times a day, sometimes several times an hour, seemingly at random. Obviously, it is really annoying. Is anyone else having this issue? Has anyone come up with a solution? Thanks in advance to anyone who responds.
