The problem is when I complile the apk file, camera is not on focus, and the device can't read the target image? I've try to find info around the forum and into the net in general, there is no clear conclusionс.There is a section here in Vuforia called Camera Focus Modes:https://developer.vuforia.com/library/articles/Solution/Camera-Focus-ModesHowever there is no clear information where and how I can edid the code. For example I would like to make my camera continuisly auto, the questions are, what should I do?1. Probably - creating a script - what have to be inlcuded into this script?2. Where should I attach this scrip after writing it? to AR directly or?I will appreciate any of your help.I'm using vuforia 5.0.10, Windows 10, Unity 5.2.4f1
