Replicant

Hello,
I have a problem on my Galaxy S3 GT-1300, with Replicant 6.
Note that my partition is encrypted.

Trying to export my contacts in a VCF file, I failed because Contacts refuse to export more than 500 contacts.
Since I urgently need this, I installed Fossify contacts to export my contacts.
When exporting, it export in /storage/emultaed/0 but failed to write the file.

It seems I can't change the rights for this directory:

I tried a

usermod -aG sdcard_rw u0_a92

where u0_a92 is the account of the app seen in /data/data but usermod is not found.

Do you have any idea how to make /storage/emulated/0 writable for an app?
