Vuforia based Unity3d Game blurry camera

Question

I had been trying a app that I developed in Unity3d on multiple android devices. For some reason in some devices the camera seems blurry.Can anyone help me out please?

Answer 1

FOCUS_MODE_CONTINUOUSAUTO works well on all of my Android devices. Read the article below for more info.

We encourage using FOCUS_MODE_CONTINUOUSAUTO in your applications whenever it is available on the device. When setting this mode, if the return value of setFocusMode() is TRUE your application will provide sharp camera images for both superior rendering, as well as for robust tracking performance.
