Can't Zoom

I am able to access the camera through android, however, when I try to zoom in, nothing happens. Is there a file identifying the camera as a front facing or back camera?

 

Hi there @ManicLalo,
and welcome in this forum!
To answer your question I need to know: which UDOO are you using? Which Android version?

 

I'm using the quad/dual udoo and android 6.0.1 beta 4

 

This file you're talking about identifies the camera as back camera, as you can see it yourself here: https://github.com/UDOOboard/android_device_udoo/blob/android-6.0.1/imx6/init.i.MX6Q.rc
