I can confirm this. Just tested on my Venue 10 7040. Apps moved to SD card are removed from the home screen after reboot.

This problem seems to reach beyond being a Dell issue (or anything they can do about it). Searching Google for this problem reveals lots of reports of the same problem on a variety of devices running Android.

From what I gather this is a problem with the launcher itself. No reported fix for this problem that is at least a year old.

I haven't installed Nova Launcher yet, but several reports say that third party launchers don't have this issue. I will post again when I install another launcher app.

Lastly, robertszak, looks like there's very little about the Venue 10 7040 on this forum. And you're right, the disappearing icons is very annoying.
