Found this Command here:

https://xdaforums.com/t/how-to-prepare-smartwatch-for-advanced-functions.4511103/

In Pixel Watch Forum...

Reason for this...

I have realized permission in Manifest

<uses-permission android:name="android.permission.ACCESS_SUPERUSER"/>

Have no effect for Root access...

Did few tests...

Added this line not enable in my beloved Termeinal App

And in known Root Terminals... this not removed accesses to SuperUser...

I also realized... There are Keyboard Apps... but this not finally fix my problem...

Seems really buggy...

Nothing work perfect...

Still Chaos...

Maybe this have something to do with Background Foreground... ever in Foreground Option...

For now I will backup these Keyboard APKs from my SM-R860 for study...

Best Regards

Edit 1.

Btw... what is this?

I have nothing disabled

D:\Android\ADBnew>adb shell pm list packages -d
package:com.samsung.android.watch.cameracontroller
package:com.google.android.apps.work.clouddpc

Edit 2.

Ah cool. This simplify for me to detect installed APKs easier...
