I dont know if this will work on versions that are NOT using another ROM for a backbone. I am using chevy ss4.8 and v3.3 miui. I have done this and rebooted several times and do not get an initial FC. I would imagine it will work once Zen fixes the ADB command issue with the newer versions. In terminal type: #su #echo ro.HOME_APP_ADJ=1 > /data/local.prop #reboot After reboot it should force launcher to persist in memory and reduce redraw...as well as eliminate FC of launcher on boots.
