I have never taken a selfie in my entire life. The feature is entirely pointless for me. Are there any smartphones that don’t have a front facing camera?

    It’s often also used to detect if you’re holding it to your ear, which allows the phone to switch off the screen when you’re in a call.

      i thought that was just the gravity sensor (holding the phone vertically vs slightly tilted)

        You’re thinking of the gyroscope, but no. Some phones have a dedicated proximity sensor for things like detecting if you’re in a call and have the phone up to your ear, but more and more phones (especially the budget ones) these days use a “virtual” proximity sensor which utilizes the front camera to perform the same function.

          that’s interesting… wouldn’t that kind of sensor consume a lot of battery? turning the camera on and off every time you use it, and to determine the distance I assume it’s autofocus?
