Samsung Galaxy W I8150

Swap (remap) Internal SD with External SD. To do this you need to replace (or manually edit) /etc/vold.fstab with attached one.

DISCLAIMER: Usual stuff. Do it at your own risk. I am not responsible for any damage or data loss it may cause.

You may loose applications that have been moved to SD card so it might be a good idea to move all installed apps to the phone memory.
Make sure your phone is rooted and your external SD card is FAT32 formatted.
Back up your original /etc/vold.fstab
Copy accross any data you want to be on new /mnt/sdcard from your /mnt/sdcard to /mnt/sdcard/external_sd
Unzip and put modified vold.fstab on you phone
In root explorer go to /etc
Re-mount the filesystem to R/W
Copy modified vold.fstab from wherever you have it to the /etc using root explorer
Change permissions to rw-r--r-- (644)
Re-mount filesystem as R/O
Reboot your phone

Your external big SD card should now be /mnt/sdcard (Internal SD) and your internal SD should now be /mnt/sdcard/external_sd

When you move apps to SD they will be moved to /mnt/sdcard/external_sd

The hack is adoption of the MOD provided by trip007in on XDA Developers forum - http://xdaforums.com/showthread.php?t=1088474 Many thanks.

I see no problem on call quality, I think that this depends from sginal strenght and carrier. In my case, I've noticed, that call quality is a little better when using skype for calling.

I was so interested in this phone until I saw that it has 4GB internal memory divided in 2 partitions with a 2GB internal SD partition. With android you should either have plenty of internal SD storage or none at all as many of the apps are unable to detect an external SD with the presence of internal SD.

Why the hell would samsung not just ship the phone with 2GB SD card is beyond me. I dont want to root so sadly this is no longer an option for me.

AndroidFiber · Nov 12, 2011

guys, any feedback about this phone? whats the performance compared to other samsung android phones.

qzem · Nov 12, 2011

It is hard for me to compare to other samsungs models,cause this is my first samsung,but I can sure say that performance is very satisfying and much better then my previous phone HTC Legend. I like this phone cause it is not to big, it has slick designe,runs very smooth,I can run 3D games without lags. If (when) it will get CyanogenMod it will be even better. With my regular use(some browsing,sms and other fiddling) battery last at least 50 hours or more.

Hi,

It is supposed to work this way - when you move app to SD it will go to the /mnt/sdcard/external_sd

If you want the apps moved to /mnt/sdcard you have to change vold.fstab - follwong line:

asec = enable

set asec to enable on partition where you want your apps moved and set it to disable on the second partition. I have not tested this though.

Eriks

PS. I have included modified vold.fstab as attachment. If you want that your apps are moved to /mnt/sdcard when you move them to SD use following mod (then there is little you can use your 1.7 G or of your internal memory now mounted on/mnt/sdcard/external_sd):

I have sent you an email. Original vold.fstab file attached, but keep in mind - it is from MY phone and will not necessary work on yours, especially if the modified one did not.

Hi.....

getting this phone as a present for Christmas, from my son.

Just need to ask if there is a SIM Unlock procedure for the Galaxy W i8150??

My present phone, ZTE Blade was sooooo easy to SIM Unlock, and so many ROM's, and ClockworkMod Recovery......it will be hard to get used to not having Recovery, Custom ROMs, etc.......

But, the spec is so good, I am happy to see you guys on the case already.

Thanks in Advance.

BTW: I have also put in a request for a dedicated forum for the Galaxy W i8150 here: http://xdaforums.com/showthread.php?t=1301121

I see we are second on the list now, with 76.....

Samsung Galaxy Gio GT-S5660 x 296
Samsung Galaxy W I8150 x 76
Samsung Galaxy-R i9103 x 73
LG Optimus Me p350 x 66
...........

I don't know about the sim unlock, but I think it shouldn't be a problem, since samsung has unlocked bootloader and we already gained root access, so this could be done aswell. Don't you wory about the recovery we will get it sooner or later. I've already contaced someone about this, and he is willing to help us on this topic. Also one cyanogenmod developer, already written here (arco68), has written here, that he is going to buy this phone. We need to be patient

If your biggest worry are games that install on the /mnt/sdcard/external_sd you should not have swapped the external/internal SD.

What kind of instability are you experiencing - I have not seen any yet and would like to be prepared

? Creating such vold.fstab should be easy - just allow asec to external sd and delete internal sd part altogether.

i haven't the phone but i follow an italian discussion (on the forum telefonino.net) and a man that try the mod vold (1st version) tell that the swap go successfully but the terminal often restart o the app crash and we think to try with a vold witch mount only the external....can you make this mod please??
PS sorry for my english i'm italian

eriksp · Nov 15, 2011

For those wanting to move apps to big external SD when it's mapped as /mnt/sdcard - you can try attached vold.fstab - I have not tested it in any way.
