Barcode or QR Scanner(SGSL) Clicking Sound

[Marcus_SwJ]

So I've dl ed barcode and qr droid scanner. I noticed that when I about the take pictures or scan the qr codes both of the apps made little ticking or clicking sounds...

Is this normal?? It felt like the sound came from the camera lens. So I wanted to ask whether the sound came from the camera lens itself? Or the speakers? Or is it the app itself tat were made to make the sounds tat came from the speaker??

Thank you...

I think it's just the autofocus of the lens so it can get a good scan. Mine does it too.
