AutoInput AutoInput & Samsung CameraApp

hi..
I just bought AutoInput. I test that i can send click to browser.
but when I try to use it to send click to Samsung Camera App, nothing happened.
Samsung CameraApp connects to my NX300M camera, and I try to click on shutter button.
what i need is to build intervalometer: tell the camera to take pics every 30secs or so.

I use it on my rooted samsung s4 phone. But, will it work on my non-rooted phone?
(i have non-root huawei )
thanx
