Problem not only related to Samsung.
Hi there people.
For all the folks who are saying that this problem is only related to Samsung, I can tell u are wrong.
I own a Rockchip 2918 based Ricatech tablet wich I recently updated to Android 4.0 ICS (official update downloaded from Ricatech website) With this tablet I experience the same problem as you guys with the SGS 3!
And with only 500Mb of app storage, I am in quit a pain!
For me it is also not possible to move apps to the SD card. There is just no option for doing this when i go to Settings>Apps.
Also App2SD gives the error:
The device does not have a real primary external storage, or the external storage is emulated. Moving app to sd function may not be supportedby this device
I think the problem is somewhat related to the fact how ICS sets its mountpoints for storage, since this different compared to Android 2.3 because I also had a problem with a other app wich could not find my external SD-Card wich runned fine on Android 2.3. For this app i had to change the folder the app was monitoring.
I do want to mention I also own a SGS2 wich also runs ICS, the strange thing is that I do not have the problem of moving apps to external SD-Card with this device.
