Ask HN: How do you hang up a call on Android when the front camera is blocked?
It seems that if a piece of tape or a sticker is covering the front facing camera, the phone is unable to light the screen during a phone call to hang up. Bluetooth headsets make it possible to hang up, but what about without an external interface device? Is this because of the way the phone detects being pressed up against a face so that buttons don't get pressed? If so, can it be disabled?
- praash 5y agoThere is usually a small infrared proximity sensor right next to the front camera. If you're deliberately covering your camera, you just need to locate the sensor and trim your tape around it.
- sigmaprimus 5y agoGoogle Says: In the phone app, go to menu / Call settings and uncheck "Auto screen off during calls." If this box is checked, the proximity detector senses when you put the phone to your face and blanks the screen so that you don't accidentally activate buttons with your face.
- 0des 5y agoThis option is not present in the call settings from the phone app.
- sigmaprimus 5y agoAfter looking into your problem a bit deeper it seems there are certain apps that may override these settings and force screen locks. There is also different versions of android each with different menu settings. So I would say the best option for you is to go through a process of elimination by first finding out what version of android your phone is using and doing a search for screen lock during call settings based on that version. Then if that does not solve the problem begin removing unnecessary apps and then one by one disabling the apps you need until the problem is resolved. Other than that, maybe the other comment about trimming around the camera might fix the issue. Sorry I can't be of more help, I hope you resolve the issue.
