Motorola RAZR D3 move application to memory SD I'm trying to move the apps that I have installed in the internal memory of the smartphone but I can't because the programs that I'm using say:

The device does not have a real primary external storage, or the primary external storage is emulated.
Moving app to SD function cannot be supported by this device

I'm using AppMgr II and App2SD and both says some similar.
How can I move the apps?
Root the device (in this case the razr d3)
Install the application (a game i.e.) in the memory SD.
Unroot the device (to have the last update of the S.O., i don't have find how to unroot an razr d3)


I don't have test this solution but maybe in a few weeks i will try it :)

Well, basicly the problem is that we will avoid the warranty of the mobile.
