[G3 Android Development] armSeb:
Hello,

I migrated from LineageOS 14.1 to LineageOS 15.1 (clean flash). Everything is working fine excepted the external SD card marked as corrupted by Android.

I wiped system, caches and data. I flashed these files in this order :

lineage-15.1-20180321-UNOFFICIAL-d855.zip
open_gapps-arm-8.1-nano-20180327.zip
magisk-installer

I started adb and catched the system logs:

I noticed the error : 03-28 13:54:30.472 261 264 E vold : public:179_65 unsupported filesystem exfat

The same sdcard worked fine on LineageOS 14.1. So the exfat support has been removed ?

Thank you.
