Android 9 blackview

8.3.8 seems to work fine

Seems to be related to nsenter not existing on A9. This should be already fixed for next releases, a workaround for now is: Settings → Advanced settings → Developer settings → Advanced Users → change suCommand to su --mount-master, su or sh.

thanks. that did the trick

Changing the command will force close the app...

Same problem here with same error in Android 9, I had to roll back to v8.3.8 to make it working again.

Same problem on 8.3.12.

@tecufanujacu was it fixed with 8.3.12?

@ts-ts what's your setup again?

@ts-ts what's your setup again?

My device is Android 8.1, but I get the same backup error even after installing 8.3.12. Do I need to make the following settings?

Settings → Advanced settings → Developer settings → Advanced Users → change suCommand to su --mount-master, su or sh.

@ts-ts this shouldn't be needed on 8.3.12, but you can gladly check if any of the commands would fix it.

Thank you for your reply.
After installing 8.3.12, the suCommand input field was blank.
When I entered "su --mount-master" in the suCommand input field, I was able to back up normally.
Thanks for the app fix.
