Android Question EROFS - until yesterday it worked, today not anymore

[amorosik]

Android 10, program that writes log files to

Dim rp As RuntimePermissions
log_dir = rp.GetSafeDirDefaultExternal ("App_123")

Until yesterday it worked correctly, since this morning it has been sending out
"An error has occurred in sub: mia_sub.logga (java line 1129) java.io.FileNotFoundException: log_file.txt open failed: EROFS (Read-only file system)"

Whats happens?

Whats happens?

You haven't followed the folder choosing flow chart: Flow chart to help choose folder

It looks like the secondary storage is locked for some reason.

Yes, you're right
But File.DirInternal is not accessible to TeamViewer or Anydesk or other similar with their file manager
Then i can't view/read file from phone to pc via above tools

But the question is, yesterday phone can write on secondary memory, now it can't' anymore?

Faulty memory card, or corrupted file system?

Faulty memory card, or corrupted file system?

There could also be a faulty file system on the sd card
After a few attempts, without any code changes, it seems to be going like other days
I will try to format the sd card
