BUG: Your device does not have a standard Android file selector.

[tiket18]

An error in the program interface.
When setting up anything, for example:

1. attempting to save to a file
2. attempting to open a file
3. most importantly, attempting to open an SSH key file when setting up an SSH connection

if using a non-standard Android firmware, such as LineageOS

the file selection window does not appear. An error message like this appears:
Your device does not have a standard Android file selector.
