Resoltuion to the datadata space constraint issue on Infuse

Android_Infuse_datadata.note

# Important - if the device shows as unauthorized in adb devices -l command. Then go into recovery mode and try adb shell. It will drop to you the shell as root.

# All the below steps needs to be performed in recovery mode.


The fix for the space limitation with yaffs /datadata partion is causing the phone to display low memory error when i enable corporate email on my Samsung Infuse.

The workaround i have is to move some of the data intensive applications to /data/data2 directory which is ext4 based - so far i have not noticed any challanges with performance.

These steps are to be performed in recovery mode. Use CWM to mount /datadata and /data partitions if you notice they are empty.

First make the /data/data2 directory
mkdir /data/data2

Then let the magic begin for each app you want to move

cd /datadata
du -d 1 -kc 2>/dev/null | grep -v directory | sort -nr  # shows the disk usage for the applications
ls -l     # at this step note the owner user and group for the folder com.android.email, lets assume u0_a40:u0_a40
cp -a com.android.email /data/data2
rm -rf com.android.email
ln -s /data/data2/com.android.email com.android.email
chown -h u0_a40:u0_a40 com.android.email
ls -l     

# at this point com.android.email should be a symlink to /data/data2/com.android.email 
# with ownersip chown -h u0_a40:u0_a40 com.android.email
# which can be verified with the last ls -l

# I usually move the following applications

com.google.android.gms
com.whatsapp
com.google.android.apps.maps
com.microsoft.office.outlook
