In older versions of Android the external SD would be mounted as /mnt/sdcard but now that is used for the internal memory and the external SD is now /mnt/sdcard/external_sd. This is a bit of a problem as some apps can only save to /mnt/sdcard and it quickly takes up our phone's internal memory. I have offline GPS maps and a few Gameloft games which can only save their data to /mnt/sdcard and as you can imagine free space is very limited.

What I would like is to switch this around. Basically I have a 32GB SD card that I would like to use a storage for some of my apps as it is not being fully utilized. I've searched around and it doesn't seem like there is an easy way to do this. I'm not completely sure but it seems like there are methods that might be specific to different phones which requires modifying a file in /system/etc.

Will this safely work for our phone?

Maybe the use of symbolic links could help, but I never tried it on an Android device.

I had read people Mapping the External under a directory for example the Games directory and therefore all games would in theory be on the External. I think this is what you mentioned as symbolic links.

How can you do that. I tryed a million things. Last time i installed literom with added swap internal memory to sd mod. And after i copy something in phone i loose the mobile signal. I guess the card is getting corrupted or something. How can i make it so the sd card wont be unmounted when i plug the phone in pc ?

Might want to consider this:

Root External 2 Internal SD

I've not used this specific one myself but I have used similar apps in the past.

I didn't use that yet.

But what i found untill now

1. Using Directory Bind wich makes a link between actual place of the files and where they should be. Example You put in your SD card and set the progam to tell android when is looking into sdcard/android/data/ go for files in sdcard/external_sd/
This method is good for games and files for them
2. Another thing is modifing vold.fstab and swapping the way adroid mounts those partitions. (this option is buggy somehow)
