I find often the phone is hot in the pocket. It turns out always that the camera app is active. I must have forgot to exit the app by swiping, and just shut the screen after opening the camera app from the shortcut by double clicking the power button. I find it happens again and again, especially in settings where I am taking quick snapshots, e.g when traveling or documenting events. It happens when the setting to tap or lift to wake the screen is on.
Is it possible to add a toggle to choose to also exit the camera app with the power button, and not just turn off the screen letting the app run in the background?
