I have an Acer Liquid Z5 (Z150), Android 4.2.
I want to modify the quick settings menu so I can remove the screen brightness or powersave mode buttons, but I can't find any such option in the stock rom from Acer. I looked for a System menu in settings as I typically would find them in, but there isn't any.
All I got so far are custom apps that add another set quick settings menu - I don't want that, I want to modify the default one, or at least, be able to disable it.
How can I modify the quick settings menu in this case? Or, is there any custom ROMs for this device as a last resort?
