Flashlight on - where is button to switch it off?

The flashlight of my FP2 is on and that’s not been deliberate. I can’t seem to find the flashlight button to switch it off - where is it? how does the icon look like?

Thanks!

Just swipe down from the top of the screen twice and there it should be.

And by the way, if it was not deliberate, you may have switched it on while calling if your display stays on during calls. Check your proximity sensor:

Recalibrate your proximity sensor

Follow these steps to calibrate the sensor:

  1. Please make sure your Fairphone 2 is up-to-date;
  2. Start the Proximity Sensor Tool app from the phone Settings > Maintenance > Proximity sensor;
  3. Follow the 3 steps to calibrate the proximity sensor;
  4. Reboot your device as explained at the last step. You’re done!
