16) My GoogleMaps (or other application that uses OpenGL) is freezing/irresponsive. What can I do?
Open terminal or adb shell and type these commands:
Code:

$ su
# mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
# echo sysctl -w vm.min_free_kbytes=4096 >> /system/etc/install-recovery.sh
# chmod 744 /system/etc/install-recovery.sh
# mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
