Why am I now always taking screenshots by accident? Two things:
The volume buttons are directly opposite the Lock button (aka “Sleep/Wake” button), and The combination for screenshot has changed. On phones with a home button, the iOS combination has always been Lock and Home buttons but is now Lock and Volume Up on iPhone X (due to lack of home button)
Trying to hold the phone with a stable grip while pushing the lock button means my thumb is resting on the lock button, and my index finger is on the volume up button.
Design is hard.
The position/function of the external iPhone buttons has evolved over time, and with each new generation, it seems there’s some design compromise that emerges.
In this case, putting buttons on opposite sides of the device mean that pressing one will require an equal and opposite press on the opposing button. And for the iPhone X, this results in a screenshot.
