On the homescreen of the control panel, when I hit the brightness and volume adjustment icons, it dose not take me to the correct place. I can access those settings by going around it to the the settings and typing in my password.
Those buttons aren’t shortcuts to the settings. The sounds icon is on the home screen and the Security screen and immediately takes you to silent exit arming (as a way of never causing a beep if you need it to be quiet while leaving)
The sun icon turns off the display (as stated above)
