Thx,I have already tried to use app2,but accomplished nothing.on the other hand ,whatever apps I could not install.it always say "insufficient storage available",I have already cleared the date from application manager ,but wasn't able to. I really don't know what's going on the s3.
You have to move old apps (not the new one, that you try to install now) with App2SD before you install any new apps. Then, when you free space on your /data
partition with help of App2SD - you'll be able to install new apps.--
Keep it simple, it'll become complex by itself...
