I have Archos97 Titaniumhd and i am having the same problem , i have tried same app on other android devices and it worked fine.

Hi Nicolas,

could you provide us with a list of phones/tablets where you see this occurring:

this will help us investigate the issue for the affected devices.

I have the same problem, did anybody find a solution? It seems to appear on few android tablets. Using the Mirror Video Background doesn't fix it. Vuforia is unable to detect the targets unles I flip the marker horizontally in photoshop...

Hi, what is the model and android version of your tablet? do you see this issue with the front camera or the back camera ?

Most importantly, are you able to track image targets (e.g. testing the ImageTargets sample) and it is just a flipped rendering problem, or is Vuforia unable to detect the targets ?
