The iOS Control Center contains two rows of buttons at the top and bottom of the area. The previous implementation of it made more sense to me, as the top buttons were switchers, and the bottom buttons were mostly launchers (except for the flashlight, which feels out of place).
The most recent update introducing the Night Shift feature brought a new button to the Control Center. It's now located in the middle of the bottom row and is responsible for toggling that feature on/off.
I can see how the Flashlight could have been a one-time trade-off because on the other hand, the interaction span with that particular feature is supposed to be short: you launch it, quickly use it, and get back to whatever you were doing (just like with the Camera, Calculator or Timer).
But now I don't understand the logic behind those placement decisions completely. The Night Shift button is definitely a switcher, it can stay on for a long period of time, and it does feel like it belongs to the area where most of the switchers are. I do realise that the area will become too crowded, but then again, it is possible to have two rows of icons in there, with the secondary ones grouped in a collapsible/expandable area - just like the one that let's you act on a banner notification (e.g. reply to a text message). That would also make it possible to include the switches for the Low Power Mode, Cellular Data and Auto Brightness in that quick access area, this way making it even more feature-rich.
Before you tell me this actually belongs to Apple's feedback website, let me finally ask my question: is there any logic behind this placement? It just doesn't feel right, consistent or predictable. Yet I'm sure they know what they're doing, which makes me wonder if I'm missing something.
I did a search before asking to see if this is not going to be a duplicate.
