I am sure my sd swap will work just fine, in the dev section.I found any method to use external sd for app data: https://play.google.com/store/apps/details?id=com.devasque.fmount
Folder mount.
This method is better for me now.
True.Сard swap has a one point that I do not like.
In "Settings - Memory" shows the wrong size and mount point of external sdcard. -> & other apps shows like this.
