Zenfone Max 4 X00ID ZC554KL
Android 8.1.0

I have tried several things to move files. The cable works the best. I have had the phone format the card.
Windows moves so many files and then if the phone is interrupted at all it starts corrupting the files or half copys the amount of files. Even with the screen lock turned off and the WIFI and LTE connection off.

Is there a windows driver for this phone?
Any Files moved on to an SD card have a problem writing. EXfat file system is not as repairable as NTFS.
I would love to use that instead.

I cannot find a Authentic Asus page with the drivers or any kind of downloadable firmware.
