((install games bigger than ur internal sd))

Samsung didnt gave the way to move apps on ext sd on sgs phones.
That is what we call a dumb move.Now you are thinking about installing games like gta sa on your star.But the storage space not allowing u to do it.Then here's the solution.
Download FOLDER MOUNT app from google play.Its a free app but u can buy full version and unlock extra features.

First of all extract ur game to external sd.

For example I m taking gta sa.
Now after extraction,u will find the main.xxx.aaaa.obb file on a folder like com.rockstargames.gtasa on ext sd.
Just hold on folders name and copy it.
Now go to ur internal sd/Android/obb folder.
If there isnt any obb folder,just create one.
Now open obb folder and create a folder inside it and it exactly like the game folder was.(I mean,create a folder by naming com.rockstargames.gtasa,what u copied a little ago)

Now open fmount.Click on plus sign from right top corner.Give a name for the game.
On 2nd box,u have to choose the source folder where data is stored.
Go to internal sd/Android/obb/com.rockstargames.gtasa and choose it from the right top corner.
Now,fmount will ask to create destination folder automatically.
Just click 'yes'.

Now make the pair by clicking 'ok' sign from top right.

Now a pair is created.
Go to ext sd where u extracted the game data and put com.rockstargames.gtasa folder in ext sd/Android/obb folder.
It will ask u to overwrite,click yes and the folder will be replaced.

Now install apk file.

Go to fmount.
U will see the pair u created a little while ago.

Just click on the pin on right side.
Its will turn green.
Wait 5 sec.
U will see
"" mounting folder"" on notification bar.
Now open the game and enjoy.

Sorry for my bad english.

Press thanks if it helped.
All credit goes to the creator of folder mount.
