[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] manuelsilv:
Hi,

Just to report that using madOS 7.1.2 ROM with cache and data filesystem formatted as f2fs, the phone is faster and some instagram and snapchat video lockup are not happening anymore.

EDIT:

I'm now a f2fs fan to the point I try to make a all-f2fs(system/cache/data) madOS 7.1.2 based update.

Unfortunately will not work because the MAD recovery kernel will not mount f2fs filesystems :(

This is the mod file I made based at madOS 7.1.2:

https://mega.nz/#!crJRHTIZ!YB7HnUzDRcFXkw8NrtiVdRqPyBIB1rU-Er1mEYm8gzU

The files I modified:

- fstab.mt6752

# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
