The new Fire TV Stick 4K MAX (Fire OS 8) is equipped with a system file picker (also known as documentsui or SAF file picker) that is nearly non-functional. The file picker UI is mostly unusable with the TV remote, except for the recent files section. Additionally, the directory tree opener UI does not function properly, except for creating a directory. Is there a solution to replace this UI so that most apps designed for Android 11 and above can successfully open files on the new Fire TV?
