what device are you working with? I’ve got an i65 that i can test twei_camera with. is this problem specific to one device or do you need to be able to check this for multiple models?
but I’d guess (until i verify this) that you’re looking at the right thing, that TWEI_CAMERA is your trick. if you’re pulling extinfo after every scan, then you should see an alternating camera. top then bottom then top then bottom…. and if you see top top or bottom bottom then you’ve got your issue.
but my question here – then what? and why?
I dont understand when/where this would matter. But I’d like to be able to recognize when I should worry about this.
