how mount external drive with ext4 on android 5+ ?

[Sérgio Basto]

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

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