I didn't do this but learned it from http://forum.xda-developers.com/showthread.php?t=1642006 and D2dyno work. I only adapated it to work on the AN 7 G3 As usual I'm not responsible if you brick your tablet. Only know tha it worked great on mine and now have Internal Sd Storage of 32 gig with an Ext Sd of 2.12 gig. I would read D2dyno link very well before you try it and then do what I will show you to change on the AN 7 G3. Also before you do ANY changes, you should have all apks installed or moved back to the tablet or you will have to reinstall those apks left moved to the sd card. Also copy all files and folders on the internal sd card storage to your External Sd Card, this will keep things from not working correctly as you will see happen to one person on D2dyno's comments.

   OK now if you have read D2dyno's Post and think your ready heres what you ned to do for the AN 7 G3....

 Have an Explorer like Root Exployer or ES File Explorer (I used ES File Explorer) and make your you have R/W permissions set in explorer settings. Now go to the tablet root and /system/ect/ and look for this file "vold.fstab", copy this file and save somewhere safe like your micro sd card, then open the file on /system/ect/ with the explorer text editor and go down to these two lines

sdcard /mnt/sdcard auto /devices/virtual/block/nandi dev_mount 

extsd /mnt/extsd auto /devices/platform/sunxi-mmc.1/mmc_host

 

Change these two lines to look like below, all you will change is  sdcard and extsd.....THAT IS ALL, make sure to change nothing else and to also have the same space between everything

 

sdcard /mnt/extsd auto /devices/virtual/block/nandi dev_mount 

extsd /mnt/sdcard auto /devices/platform/sunxi-mmc.1/mmc_host

After changing sdcard and extsd close file editor and it should say changes saved, I still opened the file backup and made sure that the changes were saved. If Explorer File Editor says NOT SAVED then you DO NOT HAVE R/W set in Eplorer and must start over.

 If all is changed and looks good the shut down your tablet and the start tablet back up, mine took a little longer to boot the first time so don't get excited. Now look in tablet settings under Storage and you should see your mirco sd card as Internal Storage and the tablets as EXTSD.

 Save the copy of original file somewhere safe and a copy of the file that you editited. To change back all you have to do is replace that file with the copy and reboot to be back as original, then replace  with the altered file and reboot to be back at Miroc sd card st to Internal Storage.

  Hope this helps someone.

This really works well and now I have 32gb internal sd, gives plenty of room to add all the apks, movies or what ever I want too. Easy to change back also.Laugh

I think that they run a little smother or at least open faster. I was watching that as that was a concern of mine also. You still have to move the apks in settings application to internal sd from tablet. I haven't downloaded an apks to sd yet, so as to set automatic install on sd if apks allows. It should work fine tho,

Just lucky as I was close by when you posted. Just save a copy If the original vold.fstab and then a copy If the altered vold.fstab file. Reboot after altering vold and micro sd should be your internal sd. If you want to change back, Just copy original saved vold and paste on /system/ect/ overwriting altered, reboot and back to stock.Laugh

I have just measured the Arnova 7 G3 internal storage speed with Arctools and I'm getting rather fast numbers: Read ~ 19 Mb/s, Write ~ 9 Mb/s ... so there's probably some speed benefit moving the apps on the sdcard if it's a class 6 or faster.

There's probably an impact of the filesystem on the sdcard as well, not sure how FAT32 compares with ext3...

Cheers.

Here's a stock one:

## Vold 2.0 fstab for HTC Passion
#
## - San Mehat (san@android.com)
##
#######################
## Regular device mount
##
## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
## label - Label for the volume
## mount_point - Where the volume will be mounted
## part - Partition # (1 based), or 'auto' for first usable partition.
## <sysfs_path> - List of sysfs paths to source devices
######################

# Mounts the first usable partition of the specified device
#/devices/platform/awsmc.3/mmc_host for sdio
dev_mount sdcard /mnt/sdcard auto /devices/virtual/block/nandi
dev_mount extsd /mnt/extsd auto /devices/platform/sunxi-mmc.1/mmc_host /devices/platform/sunxi-mmc.0/mmc_host
dev_mount usbhost1 /mnt/usbhost1 auto /devices/platform/sw-ehci.1 /devices/platform/sw_hcd_host0 /devices/pla tform/sw-ehci.2

As I'm not sure about the formating here, I've attached the file as well Wink

I'll check these vold.fstab modifications later, when I've made progress with Google Play setup with Arctools on the Arnova 7 G3.

Cheers.

Thanks for the information on speed, I'm running a class 4 32gb micro sd and I knew that the apks seemed faster. Good to know.
Lohtse are you good now? Was out shopping, I have both vold files as I was afraid I might screw up. Saved them bow on my 2.12gb extsd ūüôāLaugh

I was going to upload a picture of my storage space in setting originally but couldn't find how to attach a file. Still can't.
