Thread: Beam scale/camera setup

Hi,
I want to set up my Samsung mobile camera to zoom in on the redding powder scale beam for powder weighing. Just to make it easier to see. I've made up a simple stand.

My problem is after much stuffing around I just can't get the camera screen to stay on more than about 2 minutes. Which means I have to put in my pin and set it all up again.
I've set the mobile screen time out to the max (10 minutes) to no avail. Camera still shuts down.

Would like indefinite but 10 minutes would be good.

Can it be done?
Any suggestions?
