Well, maybe it wasn’t clear from my description, but by attempting to press the power button my intention is not to “power it down”, but rather to “lock” it.
…which I do countless times a day, and apple put their “screenshot” combination buttons on opposite sides of the screen, EXACTLY where I hold it.
Because if I don’t - it butt-dials random numbers. And by random - I don’t mean digits, but something a lot worse - a russian roulette of employers, acquaintances, municipal services, businesses or anything else that happens to be in recent calls, or contacts, or numbers that dialed me, or that I dialed, or… you get the idea.
