I wanted to disable status and navigation bar on Android 9. so, I used the below commands do disable and enable both the bars.

Disable

pm disable com.android.systemui

Enable

pm enable com.android.systemui

But i noticed that, disabling systemui, disables the SD card. That is the SD card doesn't get detected in file manager. I even checked via adb shell just to be sure - ls /storage/. And i couldn't find SD card. Why is that? Is there a way to access/ re-enable SD card without enabling systemui?
