for app2sd on optimus, you must have root level.
before install app2sd, please check you internal memory (setting-sd card & phone storage)
and remember your free space.
1.Partition your sdcard (i use paragon manager)
make 3 partition on your sd card.
example : your sdcard is 4 GB
1st partition in FAT32 3 GB
2nd partition in ext2 700mb
3th partition swap 300 mb
2. download this file link
3.extract the download file
4.copy all file to sdcard.
result : /sdcard/app2sd/
5.connect your phone from ADB File and type this command :
-su (approve with superuser aplication in your phone)
-wait...and your phone will reboot
6.after reboot, please check your free memory in internal memory (setting-sd card & phone storage)
what happen in your memory?
