"How to fix "slide to power off" screen that randomly shows up?"에 답변Guys, I had the same sort of problem but it came without water damage or dropping the phone (iPhone SE). In my case, the inside of my silicon case was very dirty. Basically so much dirt accumulated above the power button that with its thickness it was enough to push down the button to an extent that it caused this power-off screen issue. I wouldn’t be surprised if someone from here would have the same issue. My theory is if you drop it in water (assuming that the inside of the phone has dried out and there isn’t any malfunction due to water ingress) the dirt between your phone and case can “swell” pushing down the button. Anyway, hope this helped.
