I have gotten an app2sd type solution to work for this phone so here I am registering on the forum to share. I also want to thank you guys for the info about ROM development as that was how I found this thread to begin with.
Starting with the obvious the storage space on this phone is lacking, but with my solution here I have managed to install everything I want onto the phone and still have about 500MB of space left... I should probably clear some cache or factory reset and start from scratch but haven't had time.. anyways, onto the solution!
YOU NEED ROOT TO DO THIS!
The program you will want is
Link2SD (directorybind didnt work for me and caused more trouble than it was worth). Here are my tips on Link2SD.
First of all you will probably need an adapter for your micro SD so that you can put it into your computer (not while its in the phone, but directly).
You will need to format and make a second partition (don't worry you can backup for files drom the SD and move them back when you are done).
Full instructions
here (How to install and USE Link2SD / Read below for my tips for the galaxy victory 4g LTE).
TIPS:
First of all I used the ext4 file system and it works great.
Secondly, you don't need to go crazy on the size of the 2nd partition like I did. I'm only using 1.1GB of 10GB on my 2nd partition right now... I would say 2GB would be more than enough, but if you have the space you could go with more... 3GB seems like overkill though as it links files, so some data goes on internal (thus I have 500MB of free space. If I were to fill up the internal memory with linked apps I'm pretty sure I wouldn't break 2GB... but maybe go with 2.5GB to be safe. or 3.. your choice... just don't do 10GB like I did, its a waste!
MAKE SURE YOU HAVE A FAST CARD! I have a class 10 32GB SD card and it works great.
Other than being able to use ext4 about 2-3GB in size, follow the directions to the T and it will work!
A few more tips... use Either titanium backup or use
ROM Toolbox (like I do; I have pro version and not sure if you need it to back up app settings) to backup the data from TouchWiz home (in case the homescreen loads faster than the partition and you lose your homescreen layout)... its annoying but it has happened on rare occasions like if I pull the battery. It doesn't always reset the homescreen but it has happened. It just makes the icons on homescreen get reset because the partition loaded after it, the apps are still there. Read on for my tips that have prevented this from happening to me again (knock on wood).
MAking Boot faster:
First of all you can use ROM Toolbox or
Autostarts (i like this app and bought it years back; so this is the one I used) to ween down on the apps at startup, this will help boot times go faster so that the mount happens quickly). The other KEY APP to use is free called
Rescan media ROOT (this will stop media files from being scanned at startup and they will only scan as needed / usb debugging needs to be on when you first run the app to disable media scanning). Rescan media root helps a lot with startup speed.
Thats it! enjoy having space on this phone! it's great once you can stop worrying so much about running out of space!
Can't wait to try out the rom when it's finished too! Although I really am enjoying the touchwiz interface on stock. way better than my old phone. Almost dont need a custom rom, but I know the phone would be faster with a good custom!
