I just bought a new Samsung Galaxy S Duos and the Android version does not have a option to move the app to memory card. I also installed the app called "app2sd"and when I open the app it says, The device does not have a real primary external storage or the primary external storage is emulated. Moving app to SD function may not be supported by this device.

What should I do now to move the app to SD.

Can you use a terminal on the device or ADB shell to run echo $EXTERNAL_STORAGE and tell us what it says? ls -l /sdcard and ls /mnt may also be helpful. –  Matthew Read Jan 17 '13 at 19:33
please, inform us: 1) your phone is rooted? 2) do you really have a external storage sd card? –  kokbira Jul 3 '13 at 15:16

All you need to do is to create a partition in your SD card and root ur phone. Install an app called link2sd, and link all ur apps to ur SD card.

I have LG P768 Android 4.1.2. I can move apps to SD using Move2SD

some app2sd (that can't work) will show this error "device does not have a real primary external storage or the primary external storage is emulated"

Follow this link . All the details given in it . If it does not understand your external sd card as memory device you might have to create a new partition in the sd card . Here is a link for that
