Total Commander

Is it possible to implement cooperation with Shizuku? This works fine on my Samsung S24ultra, but I have to use the FV file explorer, which supports Shizuku.

This will probably be the next thing blocked by Google. Amazon has already blocked connections to ADB (Android debug bridge) locally on the device on their Fire TV devices, see for example this post.

The problem with the FireTV devices is probably the encapsulation of Google, which Amazon operates. Amazon will soon be switching to its own OS in order to free itself from its dependence on Google. The purpose of blocking ADB is to prevent updates to the new OS from being switched off. If it came from Google, the Shizuku app would hardly be available in the Playstore.
