Where do I find the setting to use the volume key as a shutter release?

[marrea]

I have just bought a Sony Xperia E5 and wish to use the volume key as a shutter release.

says:

You can choose how you want to use the volume key when taking photos.

Zoom - Use the volume key to zoom in or out

Volume - Use the volume key to adjust the volume

Shutter - Use the volume key to take photos

When I go to Apps > Camera, I can’t find the section about choosing how I want to use the volume key when taking photos.  Can anyone enlighten me as to where exactly it is?   (Sorry if I am being completely stupid here - I am quite new to smartphones.    )

It is with some embarrassment that I have to report that I have now solved this.  Initially when I went into the Camera settings all I could see under More was “Object tracking” and “Metering”.  I had tried scrolling down to see if there were any other options but could not seem to make the screen move.  I obviously was not using the correct finger technique for this but I have now persevered and discovered that there are indeed many more options available, one of which is “Use Volume key as”.  It was set to Zoom as the default so I have now changed that to Shutter.

Many apologies for my incompetence.
