Description of the issue:
When running a vuforia app the video feed appears upside down.
Exact Device Model number:
Medion LifeTab E7322
Installed OS version:
Android 4.4.2
Vuforia SDK version
Vuforia SDK 3.0.9
Platform (Andoid native, iOS native or Unity)
The issue can only be reproduced when using the Vuforia Unity Extension; when running the Android native samples, the video-background is rendered OK.
Samples:
The issue can be reproduced with the Image Targets Vuforia Unity sample.
Error Logs:
Nothing obvious in the logs
Device orientation:
The issue occurs in both Landscape and Portrait mode
Back/Front Camera:
The issue occurs with both Front and Back camera.
Camera Mode:
The issue occurs when using MODE_DEFAULT and MODE_OPTIMIZE_QUALITY.
Concurrent camera access:
I am not aware of any other software running on my device that may try to access the Camera while Vuforia is running. I would tend to exclude this.
Occurence vs. Internet connection:
- can the issue be reproduced on a first run after disabling Internet connection, uninstalling the App and reinstalling it again (with Internet connectivity OFF) ?
- YES
- can the issue be reproduced on a second run after re-enabling Internet connectivity and running the app again ?
- YES

It appears that on a few devices the video feed are inverted or maybe rotated upside down by 180 degrees;
this issue is not caused by Vuforia, but rather is due to the way the camera image is delivered to Vuforia by the underlying hardware;
