Using over 2gb sd card space for link2sd apps
Yes, Im using 32gb card.
I have kept 4096mb as EXT4 partition and rest I have formatted as FAT32. Link2SD works fine.

You can go max 4GB.


Download mini partition tool
Format your CLASS10 SDCARD 1st partition being FAT32, and second keep (4GB) it EXT2 (EXT4 might not work)
Shutdown your phone, put back your card. Star the phone.
And then start linking your files with Link2SD. I have bought Plus version, it is very useful. Since My phone has only 16GB internal memory.
