I'm using "CloudReco"
However, when I switch to the front camera, it has been confirmed in iOS the problem of feature point does not follow the video.
This problem can be reproduced when you switch to front camera in the sample app of cloud recognition.
1. launch Vuforia sample
2. Tap "Cloud Reco"
3. Tap "Start"
4. Check feature point overlay following camera image when device moves
5. Swipe left edge to open menu
6. CAMERA change to "Front"
7. Check feature point overlay doesn't following camera image when device moves
And, this problem does not occur with Android.
Is this the vuforia sdk bug?
