I have a major problem. This doesnt happen too often but when it does it creates a very bad user experience.
When I use vuforia plugin for unity usually everything works fine. Sometimes though My camera tends to hang. This is espeically noticable when i disable and enable QCARBehaviour several times in sequence. (I enable qcar, scan a tag, click on model that shows up, disable qcarBehaviour, play around on this camera, then return to qcar (enabling it again), several times) If it always happened then i know it is something with my code but it happens sporadically. SOmetimes it will happen 3 or 4 times in a row where the camera will hang and i will have to restart the whole tablet because I cannot retrieve the camera again, othertimes it will not happen for 20 or so repetitions before happening again.
I dont know if it is something with how many image targets I use or something else but it does get annoying when I have tried to fix all bad code and it still happens.
Any help or info would be much appreciated.
