z4mod Lagfix – An Alternative to OCLF
So, most Samsung device owners may have tried out the One-Click-Lag-Fix, and now here is another alternative. XDA forum member RyanZA has come up with the alternative z4mod Lag Fix.
The difference with this one though is that it uses native EXT/JFS instead of loopback mounts, which should be more stable. Other differences include using /etc/fstab for filesystem mounting as well as keeping the convert scripts outside of the kernel (compared to other lagfixes which are kernels compiled from GPL source for specific devices and hence lose out on bug fixes specific to later Samsung kernels).
The app should work across all Samsung devices without changes but still requires testing for different devices, hence you must check the compatibility table in the thread.
