DocumentsUI - No Focus for app in top left, top right or top middle menus when using a DPAD Remote

Which system do you use? Android, Ubuntu, OOWOW or others?

Android 13(Also Andorid 12)

Which version of system do you use? Please provide the version of the system here:

Latest stock firmware

Please describe your issue below:

You can’t click with a dpad remote on these menus or icons since they have no focus. Only a mouse can click on them.

Is it possible to make a patch for dpad navigation for all the menus(top left and right and middle icons where you choose a different file manager) for packages/apps/DocumentsUI app?

These menus

This is a native Android application. At present, no changes will be made, following Google’s design.

@william.lin
I understand it won’t be changed for official firmware.
Can you perhaps still help privately if I want to improve it for myself?
Lots of game emulator apps and Magisk requires it and then you can’t use a remote or game controller to select files and need to use a mouse.

@mo123 Can you refer to the following methods to see if they are effective?

packages/apps/Settings$ git log -p
