Is there any way to change the sound that accompanies unlocking the device? It is now a camera shutter sound. If I am in the company of other people, the unlocking sound of the device draws their attention, and some people ask if I take photos of them ... I use the lock / unlock sound to have additional confirmation that the action was successful.
I know that Apple also uses the shutter sound of the camera when unlocking it, but if I wanted to deal with Apple's stupidities, I would buy an iPhone.
