how mount an external drive formated with ext4 on android 5+ ?

[Sérgio Basto]

Hi,
After bought an android device with Android 6.0.1 
I don't believe , android 6 does not read pendisk with ext4 fs , says that they are damage . This is a huge regression from Android 4 or less read it !

I can't find a way , without root the device and lots of work [1]

I have 80% of my external disk with ext4  so this for me is a big problem ...
