@doniks That doesn't work either. Tried saving it to file like this, also doesn't work.

While Ubuntu Touch is a bit different than Ubuntu Desktop, I think it would be better if we have more control over hardware in mobile devices.
The main problem I usually have is with the sound system. Most of the phones uses multiple speakers, also we use headphones and external speakers for personal purposes. If I have the the control over all of the speakers simultaneously like simply in the navigation bar, I can control what apps to use which speaker and also what ports, It would be the best.

I am not just asking about improving the controls of sound system, I am also asking for other hardware like camera, bluetooth, wifi and other sensors. Wouldn't it be better if I can use my triple back and front two cameras at the same time? I meant I will have 5 different cameras at the same time running. Also have the control which camera to use which apps in the navigation bar. Same for the others.

If we have more control over hardware, It will feel like more Linux. Maybe I didn't ask the right question. I feel like its really have more complex uses in real life and It is being part of us. You may say there's some third party apps to control them, but I believe that doesn't feel like Linux. So, thank you if you take it in mind.
