Android 6 and above allow you to turn part of any memory cards into native storage for Android, a process known as adoption. That causes the contents of the adopted file system to be encrypted by the phone, you can't pop the card out and read it in another computer or phone. Android will get upset if you take that storage away!

It is possible to split the memory card so as to have some capacity adopted, and the rest as FAT32 for the traditional "external" legacy storage.

You connect to your phone over ADB to get a list of adoptable capable storage devices like this:

$ adb shell sm list-disks adoptable

then you decide how much you want to reserve as a percent of the capacity (note that a 64GB card will have only usable 60GB). To set aside 80% of the capacity as legacy:

$ adb shell sm partition disk:NNN,MMM mixed 80

You can then go into Settings->Storage and see the separate storage spaces.

If you decide to take the card out to back up the files in the FAT32 space, I recommend you shut down the phone beforehand, and put the card back before starting up.

If you decide to repartition the card, you'll see the "ghosts" of old adopted storage list in the Storage settings and you can remove them.

I don't seem to have any wifi functionality.

I ssh'd in over the usb ether, and I see a wifi device,

root@gemini:~# ip ad show dev wlan0
34: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 00:09:34:5a:83:db brd ff:ff:ff:ff:ff:ff

root@gemini:~# ip link set dev wlan0 up

root@gemini:~# ip ad show dev wlan0
34: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 00:09:34:5a:83:db brd ff:ff:ff:ff:ff:ff

root@gemini:~# connmanctl enable wifi
Enabled wifi

root@gemini:~# connmanctl scan wifi
Scan completed for wifi

I installed connman-ui but if I run connman-ui-gtk at the command line, nothing happens. There's nothing in the menus that looks useful.

I was ssh'd in, over USB ethernet emulation mode, and typed in "sudo init 6" to reboot, and nothing happened.... for a long time! screen was blank, didn't respond to ESCape/ON/OFF (but I didn't force it).

after what seemed like forever, probably only 30 to 40 seconds, it did reboot by itself

I seem to be stuck with the G only showing the date and time, a dialler if I swipe left, wallpaper choice if I swipe down, and camera if I swipe up.

can't seem to do anything else.
