When I try to move a device to a different folder, some of the applications that get installed through packages (apk) are getting errors: "File IO error on device. Check Storage/Permissions. ". It is occuring randomly on some application... means I tested it more than once and the result was different each time.

When I "force package reinstallation" everything works fine... but I dont want to do that for 100+ devices.

Does anyone know something about this?
Is there a fix or workaround?
