I’d always kind of wondered how “butt-dialing” could even happen, as it seemed extremely unlikely.
But, just now, I went to pick up my phone and fumbled it a bit, and when I turned it around the screen had switched to one of the swipe-to-the-side notification screens, and on that screen was a “Call <last person I called>” shortcut. So yeah, I could see how I you could accidentally reach that.
I put the phone in my pocket, and about a minute later, my mom called me, wondering what was going on. Turns out it had called her, without me even noticing.
Guess it’s easier than I thought!
