Hi abcxyz,

it seems we have identified the issue, i.e. a conflict between the startup screen and the GL view; the issue only appears on some devices, like your;

here is the solution (code changes in the sample, add the bold lines marked with //NEW):

                In the run method from the Runnable mSplashScreenRunnable :

                            // Start the camera:

                            updateApplicationStatus(APPSTATUS_CAMERA_RUNNING);

                            // Show the startup screen

                            showStartupScreen(); // NEW

                Also note the changes in these methods:

    /** Show the startup screen */

    private void showStartupScreen()

    {

        if (mStartupView != null)

        {

                mGlView.setVisibility(View.INVISIBLE); // NEW

            mStartupView.setVisibility(View.VISIBLE);

            mStartScreenShowing = true;

        }

    }

    /** Hide the startup screen */

    private void hideStartupScreen()

    {

        if (mStartupView != null)

        {

                mGlView.setVisibility(View.VISIBLE); //NEW

            mStartupView.setVisibility(View.INVISIBLE);

            mStartScreenShowing = false;

        }

    }

 Please confirm  if that solves the problem.

Model number: LT18i

Android version: 4.0.4

Vuforia SDK: 2.0.31

Thanks Alessandro!

Forgot one thing:

could you provide the exact model number and Android version of the device ?

and what is the Vuforia SDK version number that you are using ?

Thanks :)

OK. Let me bring this to our team for some verifications. I will get back as soon as I have feedback.

I tried the ImageTargets sample and it works fine.

Hi,

can you try the ImageTargets sample to see if you experience similar issues (e.g. "about" screen disappearing before pressing star) ?

This is to verify if the issue is only concerning the VideoPlayback sample.
