I'm a lefty, so I've probably adapted to this over the years, but I regularly use my phone's camera with one (left) hand. At least on Android (my recent phones were the pixel 3 & pixel), the shutter button is low and in middle. Pulling my phone out of my pocket, unlocking it, opening the camera app and taking a picture all with my left hand is a pretty common task for me and not really any trouble at all.
