I have a fairphone, and I just bought a 128GB sd card for it to expand my storage. I chose the "Use as internal storage" option. Now I want to do stuff like, download osmand maps onto it, download stuff onto it through newpipe, and, like, actually access the files on it through a file manager.
The thing is, I can't see the sdcard anywhere in the file manager. Using termux as root, I seem to be able to access it on /mnt/expand/q506de..... but nothing except root seems to be able to actually access that. Like, what am I supposed to do here? Should I have formatted it as portable storage? Do I need to, idk, create a folder on it, give it read/write permissions for the user and symbolic link it to /storage/emulated/0? Can I still put apps on it if I format as portable storage? Do I have to choose between storing files or apps on it?
