I bought one of those budget phones that claimed to have 4GB of internal storage, but it looks like there is only 1.08GB. I don't know why it says that I only have 1.08GB if I already used 1.12GB for apps.

I removed all bloatware and moved all my APKs to the SD card, but I still don't have enough space for Google Docs, etc.
The main culprits are SpanishDict and Facebook, which take up 200MB of internal storage each (at /data/data/com.spanishdict.spanishdict and /data/data/com.facebook.katana)
Of course, I googled before asking and such, and I used this program called FolderMount. But it doesn't seem to work well with moving things outside of the SD card, defeating the whole purpose of it.
Does anyone know a way to actually move app data from the internal storage to the SD card?
Btw, I am using a Lanix X200.
TL;DR no space on the internal store because of app data on /data/data. Need to move it to an SD card.
