AutoTools Can't change setting on this device - screen_auto_brightness_adj

Hi,

I'm trying to set "screen_auto_brightness_adj" on my OnePlus 5T (Android 7.1.1), I can successfully do so from Windows with:

Code (Text):

ADB.EXE shell settings put system screen_auto_brightness_adj 255

I have also preformed the first and now 2nd (after some reading) of these commands:

Code (Text):

adb shell pm grant com.joaomgcd.autotools android.permission.WRITE_SECURE_SETTINGS
adb shell pm grant com.joaomgcd.autotools android.permission.CHANGE_CONFIGURATION

In Tasker I get:

Code (Text):

Error: 166522839
Can't change setting on this device: you cannot change private secure settings
 

Any ideas?

 

Thats OK except that I am rooted with Magisk and "AutoTools Root add-on" has been granted root permissions.

 

yes, thats what is failing...

I have now also successfully done it without autotools by running the shell commands from tasker.
