Got the 'stalling' problem? Rooted? Try this...

Try at your own risk... if things go wrong you'll need to wipe your device. I have done this and it seems to have eradicated the 'stalling' i've seen on the device...

You need to be rooted and have ADB on your PC to run these commands. If it's confirmed this helps, i'll make the process easier with an 'installer'.

Enter the following commands in adb on your PC with your device attached (rooted, with USB debugging enabled):

adb shell
su
cp -rp /data/data /dbdata
mv /data/data /data/data.bak
ln -s /dbdata/data /data/data
reboot[/code]

I've done this on mine, and i'm yet to see a 'stall'. Let me know how you get on!

NOTE: This basically moves the application data stuff from the internal SD to the NAND, which seems to be faster. The caveat is that the size limit for dbdata is about 130MB, so if you go over that with your app data, bad things might happen. On the plus side, we're only moving data not the apps themselves, so filling up 130MB will take a while. :lol:

I get this message after the first command

# cp -rp /data/data /dbdata

cp -rp /data/data /dbdata

cp: can't stat '/data/data/LeveloKment.PatternControl/shared_prefs/LeveloKment.P

atternControl_preferences.xml.bak': No such file or directory

Should I just continue with the rest?

Oh, great! Thanks, Paul! Can't try it right now since I'm heading over to Samsung HQ tomorrow in Belgium

They read my blog and contacted me after I posted a video on Youtube because they were really surprised to see the Galaxy S being so slow. They invited me to come over and have a look at it together, possibly flash some new firmware on it. So that hopefully means Samsung is working on it or will work on it soon!

Try running it again? Do NOT continue until it completes successfully!

Well this solution is not actually usable on the phone. On my device size of /data/data is already 143 Mb, and its greater than free space in /dbdata (96 Mb)

What apps do you have installed?

I was only concerned about map caching apps and such like.

My /data/data was only 44Mb.

EDIT: just tried this - works great! Definite improvement to overall responsiveness. NICE :lol:

Why? Isn't down to the applications you have and where they choose to store stuff?

Say you downloaded a mapping application that allowed you to download/cache maps from online, would that go into this data directory (I'm not sure on the APIs or any sandboxes that are available to devs when producing an android app)

Only if it was brainless... it would ideally store to the sdcard.
