Is there any tested method to mount Ext4 or NTFS partitions on Android 64 bits v5.1?

After long days trying to implement some filesystem that allows more than 4GB file size on my Jiayu S3 with a Xtreme ROM (not ROM stock, but still Jiayu official MOD) based on Android v5.1 64 bits, I have concluded that maybe, as for today (September 2015) there is no way to achieve this.

So, please, could someone successful on mounting NTFS or EXT4 (preferred) with a 64 bits Android version tell me how he did it?

I tried multiple tutorials (some from XDA) and apps, but they all fail.

NTFS

I have T700 and rooted LP 5.0.2 stock rom.
How can I get NTFS SD card mount and read/write in my Tablet ?

How do i read external hdd with NTFS file system?

Hi.

Android does not support NTFS supposedly, but you can install apps that allow android to read an NTFS file system.

I have an powered otg lead, and it can read fat32 external hdd with no problems, it`s just ntfs i am having problems with.

There are a few apps on Google Play.

Can anybody recommend an good app, I am rooted but my brother in law`s 10.5" is not, so an app that works without rooting will be great.

Thanks

John.
