Another example of this: when I bought my current phone it took me well over a week to figure out how to put it on silent, because the option to do it is no longer on the control panel you sweep down from the top of the screen.

No, now I have to actually adjust the volume to make the volume indicator / slider pop up, and then the mute button is visible.

If the volume slider was accesible through the regular on-screen interface, I might have looked for a mute button alongside it. But pressing the volume up / down buttons didn't occur to me, because those buttons are for nudging the volume one step in either direction, not for making hidden UI elements appear.

Aha, you too have a OnePlus? :-)

AFAICR, it took me much longer than a week.
