Which Android version are you using for your tests?
The paid version of my settings extension is able to set the brightness ... there also is a test project available...

hey, could someone help? im still stuck 
does the test project work for you?
Taifun
nope, it doesnt for some reason
i cant find that screen, whenever i open modify sistem settings, mit app inventor aint there
???
the name of my test app is settings and the device settings screen will be opened during Screen Initialize...
you might want to post a screenshot of what you are getting after opening the test app...

your test app did work on my device, but when i open the modify system settings on my device to try to enable on my apk, its not there for me
ok, so the extension is working fine
well, your app without the settings extension obviously does not work...
why do you think, I spent time to create the extension if we could have the result without it?

i have been using another extention, a free one that i found here on mit, but sadly it wont work
Did you try this extension which changes the brightness of the current window only....
hmmm, just tested not working for me here...perhaps needs to be compiled?
