QualitySettings.SetQualityLevel android crash

Hi,

Does not work correctly QualitySettings.SetQualityLevel. After that, the game crashes, even the device may restart. I set quality = 3 (Good).

On my ASUS Zenfone 5 (1280x720) everything works fine, but on the Nexus (FullHD) 5 and 7 crash.

Code:

     void Awake()
         {
             float width = Screen.height > Screen.width ? Screen.height : Screen.width;
             float screenScale = width / 1920;
             int qualityLevel = 0;
             if (screenScale >= 0.5f)    qualityLevel = 3;
             else if (screenScale >= 0.25f)  qualityLevel = 2;
             else if (screenScale >= 0.125f) qualityLevel = 1;
             else    qualityLevel = 0;
             QualitySettings.SetQualityLevel(qualityLevel, true);
         }

See the log from the Nexus 5.

Give any solutions please. Thanks
