Help with moving apps to internal storage

[3X3CU710N3R]

Hi I am using Samsung Galaxy SII (GT-I9100) with Android 4.1.2.
I am having a problem moving my installed apps from System storage (device memory) to Internal USB storage. I do not have any external SD card, and frankly I do not want to buy one when I have so much space on my internal storage (11.5 GB total to be exact).
Here is the exact issue. I have only 387 MB free space left on my system storage out of a total of 1.97 GB. So I would like to move my heavy apps (e.g. games like Angry birds) to my internal USB storage which has 7.47 GB free space available out of a total of 11 GB. But when I go to application manager and click on any app (which is movable to internal storage) like Angry birds and then click on Move to SD Card button (which is enabled btw) I get this error "Unable to move app. Not enough storage space". I'm really frustrated with this, I don't want to buy an external SD card and reading other threads on this topic has not proved very helpful for me.
Please help me out here. Thanks in advance.

You clicked on the "Move to SD card" button when you do not have an SD card insert. Hence, the error message pops out.

But I have read in many forums that internal storage space is also treated as an SD card and pressing the "Move to SD card" button will move the app data to internal usb storage.

If that is not so, how can I move my app data from system memory to internal storage? any ideas?

Its because you're on 4.1.2. You may need to factory reset the phone to get it done properly. In 4.1.2, the internal storage and system storage becomes united into one big drive, and apps cannot be moved to SD card anymore because they must and can only reside in the internal storage.
