Problem with creating an app with Augmented reality

The problem is- when I build the app for android, and open it on my device- the camera is very blurry, and unable to recognize my AR objects.
(When I use on my PC with a lame webcam it does work).

My LG camera works totally fine by itself.

Only when I use it with the unity app I created the problem occurs.

What can cause this?


If you’re using Vuforia for AR, then set its camera focus mode to continuous_auto. This will trigger focus automatically during play time
