The buttons seemed to be touched at random by themselves, when inside apps and the control panel. Can there be any specific reason behind this?
The usual causes for this behaviour are: dark projection surface (some brown wooden tables trigger buttons) and poorly lighted environments. As I know that you are already using a white projection surface, I am suggesting that you bring an extra light source.
Changed the lighting to 2 bulbs of 600 lumens, seems to be working soundly. Thank you
