Hello All

I am looking for phone models with android (maybe version number) that
support sd card formated with ext2 or ext3. Preferable ext2 since it's not
journaled.

I'd like to save big files (1-2gb each file) on the sd.

Thanks

It's a kernel future, and you will have to root the device to be able and
change the mount option for the sdcard (on /system partition).

I think some of the Cyanogen mods support ext4. Also I recall reading
somewhere that this might be a feature in Android L, but I can't remember
where...

What is already enabled in the kernel? FAT/ext2/ext3 ?

It depends on the device,
But probably all will support FAT (not exFAT) as it's the default for the
external SDCARD.

I've heard that some Samsung phones are running F2FS to increase
performance/decrease NAND wear. To me it seems likely that if they're
enabling that then they wouldn't be squeamish about enabling ext2/3/4.

I think the sd card I used in my htc one v was ext4 formatted, but I
don't remember now. I can check later, depending on how chag
preperations go this evening.

Thanks Efraim. I will appreciate it. I can wait a day or two.
@Rabin, I'm not interested in fat due to the size limit.

exFAT <http://en.wikipedia.org/wiki/ExFAT> don't have the same limitation
like FAT,
And there some (custome) kernels out there which come with exFAT support.

The original poster mentioned wanting to save files larger than 2 Gb.
The limit on Fat32 is 4Gb, so I don't see the problem.
