S5 Neo sensor to take selfie

[Abebaby1961]

Hi, new to the forum so hoping someone can help. I have seen in the guide that you can take a selfie by touching the sensor on the back of the phone. For some reason mine doesn't seem to work. I was wondering if this is definately a feature on the S5 Neo and if so is there a setting that might cause it not to work. The heart rate monitor seems to work ok. I know there are other options to take a selfie but it would be nice to know if this should work or there is a problem. Thank you in advance.

Didn't know it even had this feature. I just tried and it works
Hold the sensor just below camera and pic takes when you remove your finger.

Cool thanks
