I have a brand new Fairphone 3 with the preinstalled /e/ from August 2020.
Configuring it I achieved a lot. What I couldn’t manage until now is USB access from a PC to the external SD card in my mobile. I even can’t always access the SD card from inside, I mean using apps. Some apps work (Files, Total Commander), some do not (the Camera app can’t save the images on the SD card, I have also an FTP server app which also can’t - why???).
What I saw is: the app permissions for accessing the SD card (read and write) are mostly gray, why? This is even the case for apps which have read and write access (for instance the Total Commander file manager).
I have about 30GB of files I want to be located on the SD card (mostly music). What I could do is connect the mobile using a cable to a Windows PC, access the popping up USB drive named FP3 (P2P mode only, I read this in another thread) and pump all the files onto the device memory. Then I used the file manager on the mobile to move all that stuff onto the SD card. Is this really the intended way? What if I don’t have not enough space on the device memory?
On my Linux machine I could never get any working USB connection. There’s never a usable /dev/sdb1 or /dev/sdc1 I would need to mount it somewhere. This brings up a new question: what file system is on the SD card? I formatted it new using the mobile device because in the first moment the Files app said “Not usable”. A Linux machine expects exFAT (or not?).
I used Blackberry 10 devices for a long time. On such devices I could easily plug in the cable and pump everything in both directions, on Windows and on Linux, this was never a problem at all. (But while the cable was plugged in the device himself couldn’t access the SD card.)
Now it seems indeed that I couldn’t even charge the mobile using a cable plugged in into a PC. Why is this all so complicated???
