I tried using my sd card as internal storage on my Samsung Galaxy Tab S6 using this guide. But in the gui there is no option to "Migrate data", so I cannot do the last step.

It still worked in the sense that I can move apps to the SD card and they work. When I go to the Anroid system settings I get 150GB of 640GB used (i.e. total on both) and if I select the SD card I get the option to format as portable storage, so it's definitely recognized as adopted storage.

But the Samsung file manager now doesn't work anymore (keeps crashing immediately after launch, never displays) and the shared storage is still only the internal storage, i.e.

$ df -h

/data/media                            110G   94G   16G  86% /storage/emulated

And I can't access /mnt/expand/*, permission denied.

Any ideas how to fix, i.e. probably run the migrate step from terminal somehow?

    Your SD card is Adopted but data is not migrated to Adopted storage: android.stackexchange.com/a/214706/218526 Mar 4, 2020 at 12:40
  • @IrfanLatif Thanks, that seems to be it. But in the UI I don't get the "Migrate Data" option, only "Format as portable", "Rename" and "Unmount". Any idea if there is a command I can execute to have it migrate the data? I suspect Samsung just removed the option from the UI.

  • There's something wrong if the migrate data option is not appearing. Manually moving data won't work. vold won't be aware of what to mount at /storage/emulated. Personally I never used Samsung device and never came across such situation. Mar 4, 2020 at 13:09
  • @IrfanLatif Yes, well, buying Samsung was definitely a mistake I'm not repeating.

    It should be realized that forced customer loyalty no more works by locking down user's freedom. Mar 4, 2020 at 13:52
