Total Commander

There are many car headunits that have truncated android (chinese often try to optimize android for weak CPUs and cut many features that they believe aren't used). And for many 3rd party apps, that use built-in functions like CREATE_DOCUMENT (e.g. to select backup file location) and OPEN_DOCUMENT (to select file that will be loaded), both contained in DocumentsUI, but often deleted from firmware, there it comes to error messages or silent crashes.

@Ghisler
Would you consider to implement at least these activities for such cutted android devices, so that we can recommend to install TotalCmd for such units to be able to use other apps assuming that these activities exist?

How should this work? Total Commander also has to request access via OPEN_DOCUMENT_TREE to these restricted folders (except on the newest Android versions, where it can get access via MANAGE_EXTERNAL_STORAGE).

at least OPEN_DOCUMENT works in "FileManager Plus" and in "FileMaster". FileMaster has also support for CREATE_DOCUMENT, but it doesn't allow to select files on some phones (some UI elements are missing).
